Duplicate fiber root disk using just ufsdump/ufsrestore/installboot ...

I have to setup 5 x 890 servers and 4 x 490 servers. Without using jumpstart, is there a quick way to do a duplicate a root disk using just ufsdump/ufsrestore/installboot commands? If these boxes had SCSI drives, this would not be problem. Because of the fiber drives, I am struggling to figure out how to do it - because the WWNs are embedded into device tree.
Anybody got any ideas how to do it using plain old ufsdump/ufsrestore commands?
Thanks.

Hi Michael,
Thanks for the qucik reply.
The problem persists. I deleted the contents of /disk2/dev/dsk and /disk2/dev/rdsk. Then I rebuilt the device tree using:
/usr/sbin/devfsadm -c disk -r /disk2 -p /disk2/etc/path_to_instThen I set the boot parameter:
luxadm set_boot_dev /dev/dsk/c2t2d0s0When rebooting, the new WWN now correctly shows up under boot-device. However, the file system appears to be mounted as read-only again. The same errors show up on the screen, all related to starting services, cron, etc. All instances are followed by an error message of "Read-only file system".
I also fsck'ed the root partition, but this didn't help fix the problem.
After this test, I ran fsck again, and noticed that c2t2d0s0 was last mounted on /disk2, so the root slice was in fact never mounted during boot.
Is there anything else I can check with regards to the read-only mounting problem?
Thanks.

I am using a macbook pro with system 10.6.8. I just discovered that no recent files have been backed up to the external disk using Time Capsule. There is a long list of backups including most recent but no recent files, for some weeks, have been backed up. I did a full reset of Time Machine. I disconnected the external drive and reconnected it. It is not a matter of file types, no files and no folders have gotten backed up. Everything looks normal though unless one goes hunting for recent files on the back up.

Many thanks.
With those symptoms, I'd try the following document:
Apple software on Windows: May see performance issues and blank iTunes Store
(If there's a SpeedBit LSP showing up in Autoruns, it's usually best to just uninstall your SpeedBit Video Accelerator.)

It shows startup disk is full but i use just only 350gb of my hd disk from 500gb.

my macbook shows its startup disk is full but i use just 350gb of my 500gb hd.

That pretty clearly shows the drive is full. So first a question: Why do you believe there's an error? How do you know there's only 350 GB in use? Second is to do the following:
Repair the Hard Drive and Permissions - Lion
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. 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 then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu.
Again, check your drive usage for any changes.

Backup issues (ufsdump/ufsrestore) under solaris 10

Hello all,
We are in the process of migrating to Solaris 10 from Solaris 8.
On our Solaris 8 systems with 2 HDDs we have a script that does a full backup of one disk (slice by slice) on to another using ufsdump/ufsrestore + boot record. The idea is that if one disk becomes corrupt logically/physically we can boot off the backup disk and continue using the system.
This worked fine under Solaris 8. We tried to do the same under Solaris 10 and noticed some unexpected behaviour when we tried to boot off the backup disk. Solaris 10 started "reconfiguring services" just like it does it when you install the OS fresh with the message:
Loading smf(5) service descriptions: xx/117
Somehow Solaris 10 "knew" that it was booted from a different device than last time.
My question would be: how does Solaris 10 know this and could we "fool" it into thinking that it was always installed on a backup disk, so it doesn't reconfigure itself every time new backup is made (and used).

"... The real question is "how can I be sure that except smf there is nothing else in the OS affected by HDD change" and that is what I meant..."
The fact that you use ufsdump on mounted (I am guessing that you are doing so :-) file systems is risky!. Alternatively, you can create snapshots (fssnap(1M)) for the file systems that you are going to ufsdump on.
If your main aim is to replicate and reduce down time in case of root disk failure, a better solution is make use of mirriong via Solaris Volume Manager (aka SDS or md(7D)). Mirror does not guard against human errors though, such as accidentally deletion of crucial files :-) (which a backup strategy can guard against).
Hope this helps.
Regards,
S.T.Chang

Root disk craches how to retrive the data from ZFS file systems.

Hi Friends,
The solaris 10 OS (root disk) is crached.i have configered execpt root disk to all disks for ZFS file systems.We using to application.Now any possble to retrive the data.
Server model - V880
Pls help me.
Advance thanks.

If the OS wasn't on ZFS, then just rebuild the server, hook up the drives and run 'zpool import'. It should find the pool on the disks and offer it up to be imported.

All music gone, transferred to 'other', can't enable disk use on iTunes

it seems like there are a lot of people with similar problems but nothing exact..here goes:
-doing research on my macbook and i get a popup from itunes saying that my ipod was disconnected improperly (i didn't touch it and i wasn't even messing around on itunes)
-ipod restarts and reconnects with itunes and i get another pop up saying that "itunes cannot read the contents of the ipod. go to ipod summery and preferences and restore.
-i would just restore it and reload all the music butttttt like an idiot..i dont keep my music in my itunes cause it takes up way too much space and i never used any external hard drive or anything to back my music up (again..idiot..i know)
-so i read though a ton of forums and posts and see that im not the only one that this has happened to and everyone is saying to put it in disc mode, go to removable disk, copy all the music back to my macbook, restore my ipod, and put all the music back on. i also read something about clicking on my ipod icon on my desktop and going under ipod controls and changing some names (i dont konw if that was jsut for windows or what) but i also dont have an option of ipod controls
-the problem with that is that i can put my ipod into disk mode but that does me no good because i can't enable disk use on itunes because literally..my only option when i plug in my ipod is to restore it. under devices on the left hand menu, it just says ipod..not ipod with a bunch of sub categories like music and playlists and stuff..just ipod.
-normally..i would just give up and restore it but when i go to the about section on my actual ipod, it says that i have 50GB of "other" so that means that stuff is definitely still on it.
-so finally..my main question is:
is there ANY way to enable disk use on my iTunes without doing it through my iPod?..like i explained..when i plug my iPod in..that is not an option. and also..would i benefit from just bringing my laptop and ipod into an apple store and asking for help there or will that just be a waste of time?

The library on the iPod will have been damaged - hence the reason it appears empty, but the media files are still there taking up space and reported as "Other". Check out this post from Zevoneer for some iPod recovery options.
http://discussions.apple.com/thread.jspa?messageID=6273675&#6273675
Some of the tools mentioned will require a working library, but I know from experience that you can use the manual recovey method when the library is missing or damaged. If you're struggling for space you probably need to go & buy an external drive before you start. Stick the iPod in disk mode. Hold Menu+Select > 6 seconds (resets iPod) followed immediately by hold Previous & Select > 6 seconds. You can now drag the contents of iPod_Control\Music to your new hard drive. You may need to reveal hidden files & folders. Once they are on your hard drive you can create a new empty library on the drive, then import the files you have reovered and consolidate the imported library so that the files are in a standard artist\album\## track structure rather that the iPod's obscured names.

How do I enable an iPod Touch 5 for disk use?

Bit of background as to why I wish to do this: I've made a voice memo and I want to get the WAV file from my iPod Touch 5 to my drive. As this apparently necessitates the use of iTunes (Ver. 12.0.1.26) I knew I was in for an interesting time and so it has proved....
The following steps to try and bring this about are all referenced from here -> Using your iPod as a storage drive - Apple Support.
The fun begins at step 5 when it transpires that to get the voice memo file off an iPod Touch 5 I have to get my Mac Mini to recognise the iPod as a drive.
As opposed to selecting "Enable disk use", which apparently is not an option for my iPod Touch 5, I selected "Manually manage music and videos." Then, according to step 6, "The iPod disk icon appears on the desktop and in Finder windows....". Lo and behold I selected "Manually manage music and videos." .....
....and yet my iPod is still not visible as a device.
Any advice re how I get my Mac Mini to recognise the iPod as a drive or how to get the files off my iPod by alternate means would be appreciated. Just one caveat - I would prefer a solution that doesn't require syncing iTunes up to my Mac Mini at any point.
Cheers.

Try using an app like the free iFunBox. iOS devices like the iPod touch do not support Disk Mode

How do I clone an external disk using CCC?

I have a MacBook Air and because it has only 256 GB and I need about three times that space for storing movies, document files etc., I use an external hard disk to keep these files on.
I formatted this disk using Mac Extended Journal but I did not put the Snow Leopard Operating System on it. I just move files from the computer's hard drive to the disk as required.
I had a scare once where the data on another external hard disk was wiped out because of a faulty USB cord. All the movies were lost and I could not recover the data. The disk also failed to mount. This problem kept happening several times. When I got rid of the faulty USB cord, the external disk mounted and I never lost data again. I am certain all the problems were due to the faulty USB cord. I have been using the same external disk ever since and it has been working fine with the non-faulty USB cord so I am sure it didn't have anything to do with the disk and it was the USB cord that was the problem. I used the same faulty USB cord with other external disks and the same problems arose - failure to mount etc.
This is the background for why I want to make a copy of this external drive. I don't want to lose the movies and other data on this disk if something goes wrong again and want everything on another disk just in case.
I usually use Carbon Copy Cloner to make backups. But that is with a external disk that has OS 10.6.8 on it.
I really don't want to put OS 10.6.8 on the external drive where I store movies and other over-spill data on it.
How do I go about making a copy of this external disk using CCC (or using another program if CCC won't work for this)?
I have two USB ports on my MBA. I prefer to use CCC over SuperDuper because I had a problem with SuperDuper in the past.

So as I understand it, CCC will clone any disk to any disk so long as it's formatted to Mac (extended Journal) and I don't have to put the Mac operating system on the disks that I am copying from and copying to?
Thanks for answering.

IPod 5G: Disk use on both Macs and PCs.

Greetings,
I have an iMac and iPod. I have selected option "Enable Disk Use" in iTunes.
When using iPod as a external disk on my iMac,all works ok.
Problem is when I plug my iPod into a PC. The PC shows an error message: "The disk in drive F is not formated. Do you want to format it now?". Is this how is supposed to be? How can I use iPod as an external disk when PC doesn't recognize it? Can someone explain this? I know that there are different formating for Macs and PCs, but since I am connecting via USB, it should not be a problem. I am connecting my memory card reader/writer (via USB) to both PCs and Mac and it works. The same is with my digital camera, works on both platforms. And what is even more strange, when I restore iPod on PC and sync in iTunes on PC, with enabling disk use, I can use it on both platforms.
Thank you in advance for replies,
JK

It is because your iPod is formatted in Mac format which Window machines can not read (regardless if you are using USB or not; it does matter).
If you reformatted the iPod for Windows, then you can use it on both systems since Macs can read Windows formatted iPod just fine.

Unable to save PDF's from Internet Explorer. Error "The document could not be saved. The disk you were saving to or the disk used for temporary files is full. Free some space on this disk and try again, or save to a different disk."

We are currently in a published desktop environment in Citrix XenApp 6.5. Server is running on Windows 2008 R2. Users are not able to save PDF's into the redirected folders (ie Desktop or My Documents). Exactly same issue described in "The disk you were saving to or the disk used for temporary file is full...." Anyone has any suggestion??

Same problem here. Any ideas?

IPod appears on Desktop - enable disk use checked, greyed-out

Each of my daughters has a video iPod--
The "white" one - about 11 months old, now appears on the desktop when connected. iTunes opens, but the choice "enable disk use" is greyed-out, i.e. I cannot un-check this, and each time the iPod icon appears on the desktop.
The "black" iPod-- just a few days old, but essentially the same video iPod-- it does NOT appear on the desktop, and the "enable disk use" writing is NOT greyed-out, i.e. we could "check" this if we wanted.
How to get the "white" iPod to no longer appear on the desktop? I have tried resetting it, but that doesn't seem to change anything.
Also-- is there a reason why this appears on the desktop, and is that a limiting factor for any reason-- or a problem? Really just trying to understand this!
Thanks for any comments.

If the iPod is set to sync manually, the enable disk use checkbox will always be on, as iTunes doesn't know when you will be done transferring content to the iPod and ready to unplug it. The iPod will appear on a Mac's desktop while iTunes is syncing it or waiting for you to transfer content to it, or when disk use is explicitly enabled and the iPod is plugged in to the computer.

"Enable Disk Use" checkbox is grayed out, can't untick.

Hi,
I just got my new iPod 30 GB video today! I've been reading these discussions, but haven't found an answer for this tiny problem of mine.
"Do Not Disconnect" constantly shows on the iPod screen when it's connected on the computer. Many have suggested ticking off "Enable Disk Use", but here's the problem: it's grayed out, and I can't change it, no matter what. I've gone through iTunes prefs, by right-clicking on the iPod in iTunes and selecting "iPod Options". My system seems to show iPod as a movable disk, but iTunes recognises it and I can easily put music into it, so I guess that isn't a problem (or is it?).
But how could I get my hands on the "Enable Disk Use" checkbox? It just isn't "tickable" now.
Thanks!
Windows XP

If you have your iPod set to manual update, the "Enable Disk Use" box will be greyed out and ticked by default, in that case use Safely remove Hardware icon or check this link: "Disconnecting iPod from your computer
" http://docs.info.apple.com/article.html?artnum=61135
For Info:
The iPod offers three ways to transfer music from your computer. You can select one of the following update modes from the iPod Preferences menu in iTunes (Edit=>Preferences=>'iPod' tab):
1) Automatically update all songs and playlists. This is the default mode, in which your entire music library, including playlists, is automatically synced to your iPod. If the music library on your computer exceeds the iPod storage capacity, you are prompted to select a different update method.
2) Automatically update selected playlists only. With this option, iTunes automatically copies the playlists you have selected to the iPod when you connect it to the computer.
3) Manually manage songs and playlists. You can also choose to transfer music to the iPod manually. This allows you to drag and drop individual songs and playlists from iTunes to the iPod.

ITunes 10 Enable disk use

So I've poked around a bit and tried searching for this, but it appears that I'm the only one having this issue as I can't find any topics on it... am I blind or has the "Enable Disk Use" been removed from iTunes 10? I went to enable this on my iPhone 4 the other day and couldn't find it anywhere. Looked under preferences, under the iPhone settings pages and even tried searching for it via the help menu which usually highlights the option somewhere.
Am I just missing this or did they remove this option in the latest revision? If they did, is there any decent way to enable this by other means?

the iPod touch has never had the option to Enable disk use.
However you thought you were doing it, it was not an option in iTunes unless you used some other application to hack iTunes.

How to enable disk use on an iPod in "recovery mode"?

I am trying to enable disk use on my iPod classic 80GB to recover lost files. One day out of the blue, 12 days worth of music vanished from my iPod, and as my laptop that stored all of my music was stolen a few months earlier, I need to manually recover the files by first enabling disk use (at least according to the various tutorials I have read online). There should be a box you can check or uncheck in the summary of the iPod when it's plugged in, but on my iTunes, all it shows in the summary is "iPod recovery mode" and underneath a "Restore iPod button". Is the "enable disk use" option not available because it is in recovery mode or am I just missing something?

Why can't I enable disk use on my Ipod touch?

I wish to use my ipod touch as an external hard-drive. I have watched videos on how to go about it and they show that there is a greyed out check box that must be checked. This check box does not exist for me. Why not? and is it possible to enable disk use?
MY ipod is an ipod touch 4th generation, 8gb, ios 6.1.6
Itunes version - 11.1.5

You just be looking at instructions for the older iPods. None of the iOS devices such as the iPod touch have ever supported disk use. There are third-party utilities that purport to provide workarounds to allow such use, but I have no experience with any of them so I can't make any recommendations.
