Booting from Secondary BE if primary BE disk fails

Hello,
I have used separate disks to configure primary and secondary BEs.
I want to simulate a scenario where the primary BE and active disk fails.
What are the possible ways to activate and boot from Secondary BE disk?
Thanks and Regards

An easy way is to drop to ok prompt and issue a boot command referencing your secondary (mirror?) boot disk. You may want to consider setting up an alias for it whilst you are there, if one has not already been made.
A 'bad' way to do it is to 'pull the plug' on your primary disk ... ;)

  • Replication from secondary site to primary site

    When we want to replicate from secondary site to primary site then we can't use database replication. Why?

    Not sure what you mean... The replication between primary sites and secondary sites is using both database replication and file replication. See for more information:

  • Can't boot from OSX 10.6.3 retail disk

    Hi.
    I have a macbook pro and want to boot from a retail osx 10.6.3 disk that I purchased. When I try to boot from the disk I hold C or option on startup I get the apple logo with no spinning gear. It hands here for hours. Nothing happens. I hear the disk begin to work and then it shuts down.
    I want to boot from the disk and install an instance of OSX on my external hard drive. I do not have administrator access to the main OS, so booting is my only option for install. Do I HAVE to have the repair disk that came with the computer or can I use the retail copy I purchased?
    Thanks.

    In a production environment we don't run around with the original media.
    It would be nice to get a new retail release soon so I can throw it a few USB thumb drives and be able to do an install on the i5s, i7s and older core 2s. Anyone know when a newer retail DVD will be on sale?

  • IMac not booting from HD, cannot repair disc in Disk Utility

    First the problem:
    I've had the imac G5 for nearly two years and its been running without a problem, now it suddenly wouldn't start up. Firstly I get two or three grey screens in succession looking as if being drawn from top to bottom very quickly, then the apple logo and timer, after a minute or so the fans start up to full power and it stays that way.
    What I've tried:
    Reading around discussions I tried rebooting from DVD installer and using disk utility. Result: error message: The underlying task reported failure on exit. 1 volume could not be repaired because of an error.
    Because I want to sell the imac I had backed up all of my important data so I zero-wrote the hard drive in preferrence to buying a third party repair package. Reinstalled from DVD. Shut down and restarted. Everything worked except those banding grey screens appeared that were never there before. Something looks wrong. Then when i tried to reinstall microsoft office (as a test) the OS seemed to freeze and I had to shut it down again. Now it won't boot up as before. This looks like a very serious problem.
    I hesitate to buy tech tool pro in case that doesn't solve it either.
    Can't think if I did something to cause this. All I've been doing is transferring some data via ethernet to a newer mac. There was also a Lacie firewire drive linked to both computers as i was backing up stuff. One night I shut the iMac down and the next day it started with this problem.
    Well... any educated suggestions would be most welcome,
    thanks.
    By the way, the memory in the mac was purchsed from a third party and installed ages ago by myself. Never been a problem with it and have been running Final Cut Studio no trouble.
    iMac G5 2GHz   Mac OS X (10.4.7)   RAM 2GB

    Long story short, I had the same problem last week, just after installing the latest software updates. I went through all the resets and disk utility verification (multiple times with phone support -- Apple Care), then took it to the local Apple store b/c nothing worked. They couldn't figure it out either and recommended that I try to backup my data on my bootable external drive before they started messing with my hard drive, since Apple stopped providing this service. I brought it home, could not boot from my external drive, so booted from the disk again, just for kicks I ran the same verification process (this was the 3rd or 4th time). This time something happened but it still failed. So I ran it three more times (each time something new happened and then it failed, until the third time when everything worked. The only problem now is that I seem to have lost all sound???? I did immediately make a duplicate of the Imac hard drive. Any thoughts on how to get my sound back? hope this helps....

  • Help please: how to boot from clone/external hard drive because "disk cannot be partitioned because some files cannot be moved"?

    MBP Retina 15" MID 2014 2.5Ghz
    OS X Yosemite 10.10
    I have a external HDD and want to erase and restore my laptop so I can install windows via Bootcamp Assistant but I don't know how to boot from a clone to fix the issue and am not sure if when I erase and restore I will still have Yosemite 10.10? I have no way to reinstall the OS if I lose it. An average user friendly guide would be greatly appreciated please

    I do not think you have to erase your MacBook's disk in order to install Windows. First of all you can try a few things before formatting the disk.
    The first thing you should do is to check that your MacBook Pro's drive is OK with Disk Utility (in /Applications/Utilities). After opening it, choose "Macintosh HD" in the sidebar and press "Verify Disk". If it gives you any error, you will have to boot your Mac in OS X Recovery (press Command and R keys while your Mac is starting up) to repair Macintosh HD (the steps are the same but pressing "Repair Disk" instead of "Verify Disk").
    After you have repaired the drive, boot up in OS X and try partitioning the drive again with Boot Camp Assistant. If it does not work, you will have to format the drive and reinstall OS X, but I will give you these steps only if this does not work.

  • Qosmio G10 - Problem booting from ISO CD for Acronis Rescue disk

    Hi, I use Acronis TrueImage to make backups of my G10's hard drive. I need to be able to boot from the Acronis Rescue Media ISO CD that I have created. I intercept the boot by pressing F12 and change the boot priority to CD. It then says something like "Trying to establish Link", then "Media failure, Check cable" and then continues to boot up into XP. The burn of the ISO CD seems to have gone ok. My G10 still has the original BIOS v1.0. Is this the problem or should I upgrade the BIOS. Any ideas would very much appreciated. Thanks for reading this post.

    Hi,
    thanks for the replies so far. You were right it was a problem with the rescue CD. Although the software writing the CD said it finished successfully it hadnt.
    I cleaned the CD laser lens and removed a hair that was floating around inside the CD drive and then re-burnt a CD using the Acronis software. This time when I view the CD from My Computer/CD/Properties I could actually see files that were on the CD. Before it just said D: inaccessible. So then I tried to boot from the CD and this time it went into Acronis Linux system as expected but when I clicked Acronis full system option it now gets an error as it does not recognize my external drive where the backup is.
    The external drive is a Transend Storejet 2.5 80 gb partitioned with NTFS. I'm going to try to write the log to a USB flash card and seen it to acronis to see if they know what the problem is. Possibly the Linux drivers for this drive need updating g or are not even present. I'll keep you posted just incase anyone else gets this problem. Anyway, thanks to all that have replied so far as your comments definitely helped.
    Any other ideas or advice is gratefully accepted. Cheers guys.

  • How to set system time from Terminal while booted from 10.6.3 server install disk?

    I'm installing from a 10.6.3 server install disc onto a Mac Mini.  However, the battery on this Mac Mini is pretty much dead, forcing the system time back to 1/1/2001.  Through some research, this has created a problem in that I cannot move beyond the Welcome screen during setup of OS X server.  It looks like the binary has issues with the system time being older. 
    But I'm stuck in that I don't know how to adjust the system time from the Terminal Utility on the boot CD.  Can anyone help? 

    Hey, i just run in to something similar, tonight while trying to fix a computer.
    The user set the time and date on his computer to 1998 and computer locked everything including time and date in system preferences, and his user account basicly making him from administrator to guest. he could not almost any program properly that required administrator privilages.
    to fix this we used this comand in terminal " sudo date 201703162014 "    todays time and date
    20:17 03/16 2014
    we tryed everything and this fixed in 2 seconds
    ps: when you type sudo in terminal it whil give you a warning the improper use of this command is bad.... click continue.otherwhise you will not be able to execute the command.
    thanks again for this post and have a great day

  • Intel Xserve will NOT boot from hard disk drive

    I have two Intel Xserves 2.0 QC machines
    I have tried to re-install version 10.4.11 OS (don't ask) onto a Hard disk drive that is in a Disk drive caddy and inserted in the machine.
    When booting from The installation DVD media
    The disk is seen by the "Disk Utility" (the disk is partitioned as GUID boot) and the installation proceeds to the disk.
    Once the first pass of the installation is complete and the system reboots, the system shows the folder and ? mark.
    If I boot and hold "ALT" key to view all avaialble boot options the Hard Disk Drive does NOT appear as valid boot disk.
    It does show, the still inserted Installation DVD.
    I CAN boot from an external firewire drive and the Hard disk drive is visible to the OS once logged in.
    I have tried different caddy postions (left, middle and right)
    I have tried bona fide Apple supplied Disk drives
    I have tried various different caddies
    I have tried installing Operating System 10.5.*  and  10.6.8 server
    I have run SMC reset and system reset
    But still I cannot boot off from any Hard Disk Drive inserted in a caddy at the front of the system.
    Has anyone seen this behaviour?
    Is it fixable?
    Do I have replace something like the Hard Disk Drive back plane circuit board? Or even the main logic board?
    I have now run out of ideas and cannot find any help in discussions or just googling.
    ANY help would be very appreciated
    Regards
    Tony

    Antonio Hi !
    QC = Quad core  or  QX as it is written on the "pull out" serial number tab at rear of system
    I have 3 late 2006 Intel xserves
    On my intial posting I declared 2 were 2.0 machines - when I was trying to be concise
    2 of the macines are 2.66 systems and 1 is 2.0 system - all are QX machines
    the 2.0 and 1 of the 2.66 will NOT boot from the ADM and disk inside the system - whereas the other 2.66 system will.
    I have many different Caddies and these have different product/model number labels
    603-9965
    603-9545
    603-9796
    these are marked "intel SATA"
    The 80Gb was only one of the drives tested - I have used Seagate 400Gb 750Gb and 1Tb  -  all of which have been used in systems at one time or another
    and as I said the drives ARE visible once the operating system (either installation DVD or external firewire are booted from) - they are just NOT visible when the system is searching for boot media.
    Thanks for the guide - I will look through that and continue to try and find an answer

  • G5 wont boot from installation disk?

    Any suggestions for a G5 that wont boot from the installation CD? Regular starts fail at the grey screen with the apple logo. I've re-set PRAM and SMU, and replaced the battery. G5 passed the Disk Utility tests and the hardware test run over firewire from a PowerBook. I've tried booting from the CD while holding down the various keys. Runs fine in terminal mode so I've saved all my files. Not sure where to go from here. Any help would be appreciated.

    Hi choriocapillaris, and a warm welcome to the forums!
    Can we assume it booted from this Install Disc before, or could this be an Install Disc from another Mac?
    If it is the right Disc, put it in the PB, boot the PB into Target mode...
    http://docs.info.apple.com/article.html?artnum=58583
    Boot the G5 with the Option key held down & see if the Install Disc in the PB eventually shows up as a boot choice for the G5.

  • OS X Recover Disk Assistant won't boot from USB

    I just replaced my hard drive in my iMac (2008). I'm trying to get the OS installed and I don't have both of my original install disks (I believe they were Leopard disks). When I purchased Lion I did create an install disk, however. I ignorantly tried to install Lion straight up from my disk onto the new hard drive. Now, it says there's a problem with the installation and to try and install again. The problem is the install disk just goes straight to that message and I can't use it to install. I tried to Erase the drive with Disk Utility and start over, but the install disk still goes straight to the "problem" message.
    I read about the OS X Recover Disk Assistant tool and loaded that onto a USB memory stick, but it won't boot from it. I can use Disk Utility when I boot from my Lion install disk and the new hard drive shows up, the USB stick shows up, the install CD shows up, and then there's a grey line and under that with a globe icon that says disk3 and under that it says Max OS X Base System.
    Under Restore, I tried to use this Base System as a source and my new hard drive as the destination thinking that's what this Recover Disk Assistant thing was but that didn't work.
    I don't know what else to do... am I going to have to take it into a shop or can someone help me?

    If your machine shipped with Lion, most likely you cannot install SL, since it won't run on it. Details in Don't install a version of Mac OS X earlier than what came with your Mac

    Any ideas otherwise a pretty dear machine for two monthe use.
    Was just out of guarantee before fault appeared
    Thanks chris

    Hi buddy,
    > But still think bios is corrupted
    If you think so, then contact your authorized service provider. The technicians can check your notebook and try to reflash the BIOS. The technicians are really experts and so this shouldnt be a problem for them.
    Here you can search for one:

  • Tiger won't boot from external firewire

    Installed 10.4.3 DVD on clean external firewire (Extended/Journaled). Before I installed Tiger, I ran updates, and repaired permissions. Everything looked good to me.
    I'm keeping Panther on main system drive for now - so from System Preferences>Startup Disk>the external tiger drive appears and I select it. Then I select restart and the promt confirms that the computer will restart with 10.4.3. Looks good so far.
    After restart, I'm looking at the desktop, guess what? It's 10.3.9, not 10.4.3. How could that be?
    Also, when I restart and hold down the Option key for Startup Manager options - the firewire drive does not appear as an option.
    So Tiger appears in System Preferences>Startup Disc as an option, but the option doesn't actually work, and that drive does not appear at all in (Option key) startup manager.
    I'm Indexing the firewire drive now (OMG is that slow or what!), but I'm not expecting this to make any difference. I'm stumped. What am I overlooking? Please advise.
    Muchas Gracias

    R MacCool,
    "What if I manually drag and drop the 4 folders (from the Tiger DVD) onto a second internal SATA drive without partitioning the drive first? Will I be able to boot off an internal SATA drive like that? When I installed Tiger on the external firewire I see that 4 folders are there - I could drag them from that drive onto the second internal drive. Does that work?"
    No, this does not work. MacOS X consists of more then 20,000 invisible files, most of them somehow connected and referencing each other.
    MacOS X DOES boot from external firewire drives, both hard disks and DVD drives.
    Why don't you just upgrade your current 10.3.9 to Tiger using this procedure: 10.4 Tiger Upgrade: Decision tree+Checklist?
    "Why does Tiger seem to install correctly, then System Pref>Startup Disc recognizes it, but then after selecting 10.4.3 it restarts into 10.3.9?"
    I am not a technician, but it could be that the firmware is the primary source for connectivity. After MacOS X has booted the internal firewire drivers might take over and "overrule" the firmware (this is why you can see it in the startup disk preference pane) but at boot-time it exclusively depends on the firmware. This theory might be completely wrong though.

  • Did a little too much maintenence - now I can't boot from my system drive

    I figured I'd watch the Bears game this afternoon and do a little maintenence on my G4/733, currently runnint 10.4.9.
    I booted from an older (10.3.9) system disk I have in the computer, Verified the disk (all was well, no repairs needed), then booted from my Disk Warrior (Tiger) disk and rebuilt the directory. Booted from the newly verified and rebuilt disk and it started up fine. Then ran Onyx and emptied several caches, including the system cache and kernel cache. Ooops, no longer boots...instead, I get the grey Apple screen, and then it just sits. When this happened the first time, I reset the PRAM by pressing the restart button six times...still no boot action.
    The drive mounts fine, and so I'm in the process of copying the entire volume over to an external drive before performing any more maintenence. I can't do an archive and install from my supplied OS disc, as it's a lower OS version than I'm currently running. I'm loathe to do an erase and install, as then I get to perform the always-painful "make the computer work like it used to" process. And, the maintenence steps I've taken on this drive are nothing I haven't done recently on my other two Macs (both now running 10.4.10), both of which are running fine. So I'm still classifying this glitch as "minor".
    Any suggestions out there? I'm gonna try to repair the disk again, and then run the OS 10.4.10 upgrade, unless I hear different from anyone here. Idears?

    I had a similar problem. A mac started doing wierd things like not starting. All the tests showed no problem except one..I ran TechTool and did a full surface scan. It showed some bad blocks. The only way to repair was to clone to a back-up----erase and zero out the whole drive---then restore from the back-up.
    That cured it....even a disk utility did not see the error.
    Bad blocks can happen anytime, it may be no big deal but if this is your problem check it every so often and if more start showing up....start shopping..
    Cheers,
    Glynn
