Solaris root disk recovery with Legato

[mrberry]

I have a Solaris 8 host that has corrupted root disk files and I want to be able to recover the entire root disk from backup to how it was prior to the corruption.

Legato support are telling me that I have to re-install the OS to the same patch level and then resore omiting certain system files. This seems crazy to me: what if I don't know all the patches that are installed?

I have recovered a root disk before using ufsdump/ufsrestore by booting from CD, mounting the root disk partitions, restoring each indiviual file system. Once the restore is complete then you can just boot off this recovered disk.

Because the Legato client and network config is required instead of booting from a CDROM I was thinking of building a basic OS on a seperate disk, booting from this and installing the Leagto client and then restoring each filesystem.

Is there any reason that I can not do this with Legato?

hi,

your second option is the best option to do. you have to restore the networker backup savesets/filesystems on a separately mounted filesystem.

afaik, networker does not support bare metal recovery.

e.g. you have a box that runs solaris with networker client. simply create a filesystem such as /restore and mount your / filesystem from the target disk for restoration and recover the / filesystem. afterwich mount the other filessytems that you need from the target restore disk such as /restore/usr /restore/opt, etc. afterwhich just do the installboot command for the target disk to make it bootable.

its quite tedious, but i think that the way to recover completely the os from networker.

InBn0507 thank you for your reply.

I successfuly restored my rootdisk by booting off corrupted disk, labeling a second disk the same as the original disk, mounting the partitions to alternate locations and restoring to them, and then running the installboot. Which is basically the same procedure I have used in the past with ufsdump and ufsrestore.

Legato support knew nothing about this and told me that I could do it but it was not supported. Well it worked for me. Now I just have to sort out Veritas on this machine...

Hi - You might want to consider taking periodic flash archives of your Solaris boxes. Done properly, it will allow you to boot off the Solaris CD (or a boot server) and restore the O/S from disk or tape.

Good Luck!
