Selecting Alternate Boot Volume on Startup

I want to select an alternate boot volume on startup.
When I hold down the Options key while booting, I get the following text message on the screen:
"ALL -MEM request too big!
Apple PowerMac3,3 4.2.8f1 BootROM built on 10/11/01 at 14:12:47"
--- copyright and welcome to Open Firmware ---
"To continue booting, type "mac-boot" and press return.
To shut down, type "shut-down" and press return."
I never get an oppertunity to select the boot volume. If I enter "mac-boot" it starts up normally in the default startup volume.
This seems to be an error message, but I have no idea what caused it. Does anybody know?
1.5 GHz G4 tower Mac   Mac OS X (10.4.8)  

I have just sent an email to tech support at FastMac to see if they have ever heard of this problem before, but of course, I have not yet received an answer.
Unfortunately, after keeping the original CPU around for about a year, I recently decided that there was no way I would ever want to go back to it, so I tossed it out in an effort to get some extra storage space. Therefore, going back to the original is no longer possible. And, the change to the current Apple firmware was a requirement for using the CPU upgrade.
I do have an external FireWire drive for backup --- the one that I had hoped to boot to by using Option key, so I could probably set up the test that you suggested.
If I really did have a default startup disk failure, I could probably boot from a CD, and then use the System Preferences Startup Disk dialog to select the backup disk, and then restart to run from it. I'll conduct a test to be sure that this will work. If so, I can probably live with the problem.
Thanks much for your help in understanding it.

  • Always get boot menu at startup

    Hi
    I'm trying to dual-boot os9.2.2 and osx 10.4 but its' a hassle having to hold the option key at startup to choose the OS. Is there a way (possibly with the boot-args nvram setting) to get the boot selection menu at every startup?
    Thanks!
    I appreciate you taking your time to help me!

    Hi, PowerBookDude12 -
    Not that I'm aware of. You should only need to do that when you want to switch the boot OS; by default, if you hold down no keys at startup the machine should boot to the last OS set in PRAM, which is set by Startup Disk (in OS 9, Apple Menu > Control Panels > Startup Disk; in OSX, Apple Menu > System Preferences > Startup Disk) or Startup Manager (which is what you get by holding down Option at startup).
    You can also use the Startup Disk to set the OS choice for the next startup (applicable to a cold start or a restart).
    There is a way you can remove some of the need to hold down Option at startup. Set OS 9 as the boot volume in Startup Disk in both OS 9 and OSX. Then, whenever you boot or restart, if you do nothing the machine will boot into OS 9, but if you hold down the X key from the time the startup chimes sound the machine will boot into OSX instead. Holding down the X key is a one-event instruction; it does not alter the OS choice set in PRAM.
    On the other hand, if it is your custom to alternate OS's at every boot, then you can automate it somewhat by setting OS 9 as the boot volume in OSX's Startup Disk, and OSX as the boot volume in OS 9's Startup Disk. This choice of settings will cause the machine to boot into the other OS whenever you restart or boot, unless you intercede during startup.

  • My MBP runs hot in the boot volume selection menu

    I noticed that when I start my MBP holding shift to get to the boot volume selection menu and leave it there for 15 minutes or so (might be shorter, I was gone both times that it's happened so far) the MBP gets unusually hot (almost too hot to touch between keyboard and screen) and I can hear the fans going much faster and louder than they should be (I think). After choosing one of the boot volumes and checking the temperatures in iStat Pro I see that the CPU is at just under 70°C. A few minutes later the temperatures go down by about 10°C and the fans quiet down running at the usual 2000rpm.
    Why does it get so hot? How can a simple boot menu be consuming more resources than a full desktop environment plus open Dashboard (which FYI contains 20+ widgets).

    Answer: yes, it does.

  • Mac Pro will not find boot volume

    Hello,
    My Mac Pro will not find it's boot volume. Each time the computer is started, the blinking folder with the question mark is the result. A working install of 10.7 does exist on the machine's primary hard drive. If  I were to press the option key on boot, I can select the primary hard drive (after entering the password) and everything boots as normal. I have run TechToolPro on the volume with no detected errors, even after a volume rebuild. A Recovery HD partition is not on the boot volume. Should that matter?
    I really really do not want to reinstall Mac OS X. I have hundreds of gigabytes of data in question. Any reinstall/reconfig would take days to complete.
    Thanks

    So you are saying that setting the default in Startup Disk doesn't work?
    And you have not got or been using Carbon Copy Cloner or another to provide working bootable backup?
    You should have Lion Recovery on one of your drives, do a clean install.,
    I assume TTPro media scan turns up no errors.
    MOVE all your data OFF the boot drive. Keep the system OS and apps on its own drive.
    Clone the system. Use TimeMachine and cloning for backup.
    And how is the pram battery?
    Any time you zap pram you lose the default and it will look for it like you see starting with SATA0 (bay 1)

  • I reinstalled osx 10.8.2 from recovery disk, now verify disk says my hard drive is there but wont boot into it regardless which partition i select to boot into , everytime it boots me into the recovery, i need help!

    Mb pro running like garbage with 10.8.2 tried a reinstall of osx from recovery utility now the utility says my hard drive is ok but wont boot into it keeps booting me back into recovery tried restart option to select disk tried using the select startup disk from recovery, gives a message asking if i really want to boot to it and in that message is the only rime it shows a question mark on the drive dont know what to do cant find similar issue

    Your rushing and not making much sense.
    Your machine was running like garbage, so you tried to reinstall 10.8---did you do this or not?
    Disk Utility says your drive is ok, that's good.
    But when you boot it keeps booting Recovery HD, so perhaps the firmware has made a mistake, it can forget.
    You held the option key down to boot into Startup Manager, why didn't you select OS X for the boot volume?
    When you get into OS X you change the Startup Disk in System Preferences, that should take care of the Flashing Question mark issue.
    attemtping to ireinstall osx from recovery partition bar is full on install screen, but im now at -6hours remaining
    So now your reinstalling OS X like you set out to do before, it does take some time as it has to download from Apple's servers.
    If your Internet connection is slow and/or Wifi is slow then it will take awhile.
    So you should have the Flashing Question Mark and Reinstall Only OS X covered.
    You should be able to boot the machine, but your performance issues may be something else and still remain.
    Why is my computer slow?

  • Cannot repair disk errors for OSX boot volume using Disk Utility while booted from different disk

    I have tried three times to repair my boot volume (OSX 10.6.8 Snow Leopard) permissions using Disk Utility while booted up on a different volume (running Snow Leopard 10.6.4).  After hours of Disk Utility reporting that it HAD fixed the problems, an immediate click of "Verify permissions" immediately results in the apparently same continuous stream of permission errors.

    Then better luck next time around. Here are some ideas for then:
    How to Install Lion Successfully - You must have Snow Leopard 10.6.7 or 10.6.8 Installed
    A. Repair the Hard Drive and Permissions:
    Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. Then select Disk Utility from the Utilities. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally. 
    If DU reports errors it cannot fix, then you will need Disk Warrior (4.3.) if DW cannot fix the drive, then you will need to reformat the drive and reinstall Snow Leopard.
    B. Make a Bootable Backup Using Restore Option of Disk Utility:
    Open Disk Utility from the Utilities folder.
    Select the destination volume from the left side list.
    Click on the Restore tab in the DU main window.
    Check the box labeled Erase destination.
    Select the destination volume from the left side list and drag it to the Destination entry field.
    Select the source volume from the left side list and drag it to the Source entry field.
    Double-check you got it right, then click on the Restore button.
    Destination means the backup volume. Source means the internal startup volume.
    C. Important: Please read before installing:
    If you have a FireWire hard drive connected, disconnect it before installing the update unless you will boot from this drive and install the update on it. Reconnect it and turn it back on after installation is complete and you've restarted.
    You may experience unexpected results if you have installed third-party system software modifications, or if you have modified the operating system through other means. (This does not apply to normal application software installation.)
    The installation process should not be interrupted. If a power outage or other interruption occurs during installation, use the standalone installer (see below) from Apple Downloads to update.  While the installation is in progress do not use the computer.
    D. To upgrade to Lion:
    Purchase the Lion Installer from the Mac App Store. The download will start quickly. Lion is nearly 4 GBs so a fast internet connection is essential. Download time could run upwards of 4 hours depending upon network conditions and server demands at the time.
    Boot From The Lion Installer which is located in your Applications folder.
    Follow instructions for installation.

  • White Screen at Boot When Attempting to Access Recovery or Select a Boot Disk

    Introduction
    I want to share a solution for a problem I encountered that Apple technical support was unaware of (they said they would create a new kdoc when I called them to share my problem and its solution) and for which I could find no documentation online.
    First, this is really a tip rather than a question, but I did leave it marked as a question in case anyone wants to earn some points by responding with a different solution to the problem I am about to describe. Additionally, I do not have a enough points to post a "Tip" so I am just starting a discussion instead.
    Next, when I encountered the problem I am about to describe, I had not yet enabled a firmware password.
    Finally, a massive "Thank you!" to the Great Pondini (James Pond - http://pondini.org) for helping me learn so much more interesting stuff about various OS X features and functionality (all for no charge) over the years.
    Now on to why I have started this discussion...
    The Problem
    I recently purchased a new MacBook Pro (Core i7, SSD, etc.). After working with Setup Assistant to transfer everything from the most recent Time Machine backup of the older MBP I was replacing, applying all OS updates, and then enabling FileVault 2 and letting the requisite disk encryption process complete, I decided to I would go ahead and just proactively repair any permissions and ACLs for my user directory just in case any repair was necessary.
    However, after shutting down my MBP, waiting, and then starting it up with Cmd-R being pressed while turning the MBP on, nothing would happen - I would just have a white screen with no Apple logo, no EFI login, no Recovery Console, nothing (and I waited for a very long time for something to show up). My only option was to do what I really do not like doing and that was to just power my new MBP down.
    So, I tried again, this time holding down Opt while turning my computer on so as to select a disk at boot. The same problem returned.
    Just to check, I once again started up while holding down the Shift key to attempt a Safe Boot. No dice.
    Prior to trying all of this I made sure that I did have the Apple Recovery Partition in addition to my user partion and the EFI partition, so I did not understand why this would be happening. Why could I not boot into Recovery? Why could I not select a boot disk? And, why could I not go into Safe Boot?
    To be safe, I started up and logged into my MBP as I normally would, then set my startup disk to be my Recovery USB for OS X 10.8, restarted, and verified all three partitions (and, since I had my Time Machine disk connected all three times I forced the computer to power off, I verified it as well). I then set my startup disk back to my SSD, and logged in and got online to see if anyone else had experienced this issue. After making sure I was not being crazy and using key combinations that were somehow made irrelevant, I shut my MBP down and walked away for a few minutes.
    The Solution
    So what solved my problem? A good 'ol reset of the NVRAM (aka/fka PRAM). If you are not familiar with how to reset the NVRAM:
    Power off your Mac and go do something else for 30 seconds to a minute.
    Press and hold down the Opt, Cmd, P and R buttons, and then press the power button. I have big hands and this is a one person operation for me. If you are not so "lucky", find someone to press the power button as you hold those four buttons down.
    Continue holding those four buttons down through the first startup chime and then release all four of them only after the second startup chime is sounded.
    So, for some reason, I had to reset the NVRAM on a brand new MBP that had been started up only once and restarted only once when I enabled FV2. Maybe something cached needed to be cleared out following the FV2 process, or maybe something funky was carried over after it was setup in the factory and shipped direct to me from China.
    The moral of the story is: If you have strage issues during the startup of your Mac, just reset the NVRAM and try again. This has worked for a number of strange issues on various Macs for me in the past and proved to be useful once again on a brand new MBP that I never would have thought needed its NVRAM reset so soon into its lifecycle.
    Special Note
    There are two processes I always complete and recommend to others following a major software update (e.g. upgrading to a new version of OS X) and when I restore or otherwise transfer the most recent Time Machine backup to my current Mac or to a new one.
    First, following a major or massive software update, go into Disk Utility, select your system and data drive(s), and then just click on "Repair Permissions" (Choosing "Verify Pemissions" will result in having to then click "Repair Permissions" if any permissions need to be repaired, so remove one click from the process).
    Second, after transferring from a Time Machine backup, I like to make sure that my user directory permissions are good to go before any time is allowed for problems with those permissions to set in. If you are not familiar with the user directory permissions and ACL repair process (this process is not the same as the "Repair Permission" functionality in Disk Utility), here is how to do it:
    Shutdown your Mac and wait about 30 seconds.
    Press and hold down Cmd-R and then power on your Mac. Once the Apple logo with the spinning wheel shows up, release those two keys.
    From within the Recovery Console, open a new Terminal session via the "Utilities" menu.
    Invoke the following command (all one word, lowercase): resetpassword
    In the "Reset Password" application that opens, select the disk that your user home directory is on, and then click the "Reset" button at the bottom underneath the "Reset Home Folder Permissions and ACLs" heading and wait for the process to finish. Any messages displayed can typically be safely ignored. If you want to be sure, search for information regarding any messages that you do not like.
    Restart your MBP and enjoy using it.
    (Note that if you have FV2 enabled, you will need your FV2 Recovery Key to actually reset your password. This is one of many reasons that I enable FV2 - anyone can startup a Mac and go into the Recovery Partition if it exists and reset a password, but having to also enter the FV2 Recovery Key adds a nice extra layer of protection. In addition to that, setting a Firmware Password makes it nearly impossible to start up from any disk other that that which is currrenlty installed in your Mac without knowing the Firmware Password - another security bonus. If someone gets ahold of your Mac, and you have FV2 enabled and an appropriately complex Firmware Password set, then them using your Mac as their own becomes a decently difficult process. It's by no means perfect computer security, but it makes it more challenging for someone to steal and use your Mac.)
    If anyone has any other tips to share or additional solutions to problem I described, please discuss and share.

    Troubleshooting advice can depend on that information.

  • HP Pavillion DV9700 - Vista 64bit - "Unmountable Boot Volume"

    Hi there,
    The problem I have with my DV9700 is it will no longer boot.  It was working great, but the other night, I had to do a hard re-boot, and then it failed to start with a blue screen with "Unmountable Boot Volume".  This is with the original Vista 64 bit Home Premium version.  I chose the option "Self Recovery" but it just finishes up sitting there continually scanning for something? 
    The hard drive is the original factory installed setup.  My question is, how do I get my machine back up and running please?  I have a Windows Vista Backup that would run each week to an external 2TB USB drive, but I am guessing that this will not recreate an exact image of my computers state?  I would also need to have Vista running to use the backup?  Some years ago (2010), I created a complete backup to about 20 DVD's, but I am not sure how to use them as they are for recovery I think? 
    It looks like I need to buy a new hard drive but how do I go about using the backups I have to install to a new drive?  Also, what is the largest hard drive I can use?  Should I buy a SSD drive?  I wanted at least a 1TB primary drive.  Fry's Electronics has a Hybrid drive where the disk cache is solid state making it more affordable.  I was thiking of getting one of these?
    I would like to use my old original drive as a secondary drive if it is even possible to access its files.  I have ordered a SATA caddy so I can mount it into the unused drive bay of the DV9700. 
    Anyway, I would truly appreciate any help please?
    Thanks a million!!!

    Hi mtrappett,

  • IdeaPad U430 unmountable Boot Volume

    My Laptop is not working.
    When I turn it on, after Lenovo logo  I see a msg "Your PC ran in to a problem and need to restart...... search online for this error Unmountable Boot Volume."
    Then automatically PC go to Auto Repair but after few seconds that msg dissapears.
    I selected recovery option but after LEnovo logo nothing come on the screen.
    I boot up with usb recovery media then also I can not see anything on the screen after logo.
    What I can do
    Thanks

    Hi Nalinpr,
    Welcome to Lenovo Community!
     As per the query we understood that you are facing issue with unmountable boot volume in your Lenovo U430 laptop.
    If your BIOS settings are configured to force the faster UDMA modes, this error may occur. In this situation, restart your computer and enter the BIOS and load the "fail-safe" default settings and reboot.
    If neither of these issues are the cause for the Unmountable Boot Volume, then the issue most likely is caused by a damaged BOOT.INI file in the root directory of the boot drive or file system corruption.
    Follow the steps below to correct these file system issues:
    1) Start your computer with your windows 7 or any operating system which you have installed in the system CD-ROM, 
    2) When the Welcome to Setup screen appears, press R to Repair the installation using the Recovery Console
    3) If you have a dual-boot or multiple-boot computer, select the Windows installation you want to access
    4) Type the administrator password when you are prompted, if no administrator password is set then just press Enter
    5) At the command prompt, type CHKDSK /R and then press Enter
    6) Once CHKDSK has finished checking and repairing the hard drive, type EXIT and press Enter to restart your computer
    If this procedure does not work, repeat it and use the fixboot command in step 5 instead of the chkdsk /r command. FIXBOOT writes a new partition boot sector to the system partition. The fixboot command is only available when you are using the Recovery Console.
    As you also mentioned that the system hangs at Lenovo logo please try to remove the hard drive if possible and try to boot to BIOs and check, also try to run the LSC diagnostics.
    Hope this helps. Do post back if issue persists!
    Best regards,

  • Satellite P100-347: Blue screen appears on start up - unable to boot volume

    Recently I left my 2 younger brothers playing NFS Carbon on my satellite P100-347, preinstalled with media centre 2005 edition, and now it fails to startup.
    During the startup process eventually a blue screen is displayed for about a second and then it shutsdown (I manged to make out the words "unable to boot volume" from the blue screen).
    I tried booting with an XP media centre DVD but it only gives me an option of reinstalling the OS with a price of losing all my very important data. Normally I would have recovered the system but I don't want to lose my data.
    Is there anything i can do other than taking it to a technician?

    Hi
    Well, mostly the BSOD appears due to a hardware problem or serious software issue.
    In your case the software problem is possible
    Unfortunately, I think the new OS installation is the best way to get the notebook running correctly.
    Now you want to know how to save the data and files well, I think you should remove the HDD from notebook and should try to connect the 2.5 HDD via external USB controller to another computer. Then you could save the files on the other HDD
    I think, now you know that the regular backups are important and necessary!!!!

  •  Ps installation on two different boot volumes of same machine?   Ps 11.0.2 Mac PPC  and then...

    Hello, I'm new to this forum.
    My goal here is to have two different Photoshop 11.0.2 installations on two different boot volumes of one and the same Power Mac (PPC) G5 Quad, one being a Tiger 10.4.11 system and the other one a Leopard 10.5.8 system, for the purpose of installing two different modalities of the same Epson Photo Stylus 2200 printer, one with the printer set to use the photo black ink cartridge for luster and glossy papers, and the other one using the matte blank ink.
    This is because I prefer to simply change the startup disk when switching inks rather than having to delete and re-add the necessary printers.  (This particular printer does not support ink cartridge switching under any version of Mac OS X.)
    Photoshop is currently only used on this one machine.  Obviously this intended scheme fits well within the EULA conditions.
    My three questions are:
    (a) whether there is any technical issue I have failed to consider,
    (b) whether each copy of Photoshop on the same machine will have to be activated separately (in other words, is the activation tied to the CPU or to the boot volume drive?), and
    (c) if the answer to the latter question is yes, whether this will count as one or two activations for purposes of later installing a single instance of the Photoshop 13.x ("CS6") upgrade on an Intel- MacBook, since obviously C6 will not run on my PPC Mac.  Again in sum, will I be able to continue to run Photoshop 11.0.2 on two different volumes of the same PPC machine and the Photoshop 13.x upgrade on the laptop?
    As further explanation, I would use Photoshop 13.x on the Mac-Intel laptop only in order to run ACR 7.x, but would keep my PPC G5 Quad as my photo editing and printing machine running Photoshop 11.0.2, since an upgrade of my desktop machine to a comparably powerful Mac Pro is simply not an option for both financial and technical reasons (the Classic environment is essential).
    Any and all input and guidance will be appreciated.

  • System Profiler shows no boot volume

    I have a G4 imac and I'm trying to upgrade to Tiger. It meets all the reqs and the disc is the retail full version installer. The installer freezes at the select destination screen. It shows the harddrive but it is faded out and I get the spinny thing. In the System Profiler the boot volume under Software Overview is blank.
    First question is: That shouldn't be blank correct?
    Second question is: Why is it blank?
    Third question is: What do I do about that?

  • Cannot Mount Boot Volume

    My iBook G4 stopped booting properly this morning. I was installing the Adobe After Effects CS3 trial when the screensaver came on after a while, but when I moved the mouse to deactivate it, the authentication dialog did not appear as usual, so I force shut down the iBook. However, it subsequently failed to boot properly (i.e. does not boot past the grey/blue screen with the spinner). At the time of malfunction, I had an external hard disk and a disk image mounted.
    I booted from the Mac OS X Install CD, but Disk Utility was unable to mount my boot volume (though it could show the volume information and verify the disk) to fix permissions. I also tried booting in single user mode; upon typing the command "mount -uw /", I got the following error messages:
    jnl: replay_journal: from: 301568 to: 7035904 (joffset 0x41e000)
    disk0s9: I/O error.
    jnl: updatefsblock: failed to update block 6026 (ret 5)
    jnl: journal_open: Error replaying the journal!
    Aug 27 17:54:11 launchd: chown ("/var/launchd/0"): Read-only file system
    Aug 27 17:54:11 launchd: chown ("/var/launchd/0"): Read-only file system
    mount_hfs: Invalid argument
    Hence, I suspect the problem may have something to do with disk journaling, which is enabled on my boot volume. I am quite sure that the volume itself is working fine, since I was able to access my data when it mounted as read-only in single user mode.
    Does anyone here know of a possible solution to my problem? I would prefer to avoid a clean install of OS X. I do, however, have a recent back-up (created by Carbon Copy Cloner) on hand. Thanks in advance!
    Regards,
    Liza

    Does anyone know of a possible solution? This tip looked promising, but my iBook G4 only starts up in Mac OS X (i.e. cannot boot OS 9). Neither can an OS 9 computer read the iBook's hard disk, since I did not select the option to install Mac OS 9 Disk Drivers when formatting it. I have also tried DiskWarrior, but to no avail.
    Since I have a back-up of the disk on hand, I want to reformat the disk, but I cannot accomplish this using Disk Utility when I boot from the Mac OS X Install CD. Do I need any special software?
    Thanks.

  • Windows 7 RC "select CD boot type" message

    Hello
    I have tried installing Windows 7 RC on my MacBook Pro 3,1 with no luck.
    When i boot from the DVD it asks me to select CD Boot Type, but the keybord is frosen, or the mac is frosen, cant tell.
    anybody that knows howe to get past this???

    If you don't have Windows installed already, I don't know of any method to modify the DVD.
    If you have Windows, you can upgrade from Vista SP1.
    You can use Imgburn in Windows - including Fusion, Parallels or VirtualBox, to rebuild the ISO.
    Start IMGBURN in Build Mode
    Advanced tab -> Bootable Disc
    Extract Boot Image
    First thing you will want to do is extract the boot image off of the DVD created from the .iso downloaded from the beta site, you can access this while in "Build" mode.
    You should get a dialogue asking if you want to have Imgburn automatically setup the Bootable Disc – Make Image Bootable options to be filled in for you.
    While that DVD you burned is still in the drive, and after you've extracted the boot image somewhere to your hard drive, click the button to browse for a folder to add the files from the DVD to the image. Just add the root of the drive, you should then have something that looks like this.
    Now go and select folder source as your DVD drive with the ISO you downloaded and burned to the DVD.
    We are about to write to disk a new ISO after filling in the Restrictions and Options we want
    (see Jowie again if needed) When you save to disk drive with new ISO filename, it will give you a summary of sectors, size and then start writing image file.
    I was successful with prior builds of Windows 7, and Vista SP1 64-bit, but not RC - yet.
    Quoted from earlier thread:
    Using latest Imgburn and following tips on what options to select, I was able to take and modify the ISO to allow booting and not getting the EFI boot menu.

    Just entered the parameters from Jowie and it did the rest.
    Took DVD I had burned with 7077, wrote to disk, modifies it, and when burned back to new (bootable) DVD. Also worked with the system recovery CD that Windows 7 now offers to create, just have to redo the CD, but boots fine and lets me see and repair both Vista and Windows 7 operating system volumes.
    Maybe something changed in 7100 RC build.

  • Creating Standby server ---- Flash archive/Alternate Boot Environment.

    Dear All,
    I want to patch upgrade the Centralized login server which holds more than 200 users. To avoid this production outage during the downtime of upgradation, we are planning to create all the logins and application in the alternate server manually. But i feel (lazy) hesitate to create logins and copy the applications in the statndby server. Since "chpasswd" is not in solaris, i can't copy the /etc/passwd & shadow file to standby server.
    So i have the plan to achieve this by
    i) creating flash archive of existing login server
    ii) Creating Alternate boot environment in the standby server and flash restore the archive in it.
    Whether the above mentioned plan is achievable, how to create the entire flash archive of solaris os?? and how to deploy it in the alternate boot environment.?
    Regards,
    Siva

    Done, I've given the same path in Standby Database [datafiles, controlfiles] as it has been given in the Primary Database.
    MoreOver, I m manually switching logfiles at primary database [alter system switch logfile] they are copied and applied sucessfully at standby database. But the archived files that I have copied with cold backup are not applied yet. Infact they are not retrieved executing the below query.
    select name, applied from v$archived_log;
    How can I apply those archived logs? [archives that copied with cold backup]
    Regards.
