You are demonstrating some knowledge here but it's difficult for us to judge whether you know the steps to take. Therefore, at a risk of telling you stuff you already know (for which I apologise) I'm going to start from ground zero on a disaster recovery of Solaris 8 using new hard drives.

Firstly though, if you boot into single user as you did, you should be able to verify the .dmp files as proper ufs dumps by using just the ufsrestore command with the t option. This should output a list of files in the archive(s).

Now, if you're working with brand new hard drives, if now already labelled, you will need to write Sun label. You will probably need to invoke the format command in expert mode to do that:

Code:

# format -e

The next step will be to write a vtoc (otherwise known as a partition table) to the disk. You do that using either 'format' (no expert mode required) to set it manually (long-hand) or 'fmthard' if you had a prior .vtoc file that made sense. Remember that slice 2 shows the capacity of the whole drive which you do NOT changed. Slices must NOT overlap.

Next, now you have a slice that you want to restore a ufsdump to you need to make a filesystem on that slice using:

Code:

# newfs <node name> (eg, /dev/dsk/c0t0d0s0)

Next, you now mount that slice on a mount point using the 'mount' command. Changing into that directory you should find only a 'lost+found' directory; nothing else.

Remaining in that directory you then just ufsrestore using the x (extract) option the whole .dmp file into the filesystem you've just mounted.

That's it.

If you are restoring a boot disk then you will also need to write out the 'bootblk'. Search this forum or Google for how to do that (and post back here if you need help).

I hope that helps but, as I say, it's difficult to judge your knowledge level. Just post back here and post your further questions. There's plenty of help available here.

This thread might be useful to add more information (as they say "Here's one I made earlier")

Restoring a system from a backup

Also, when booted in single user mode from a DVD, you have two mount points available on the DVD; /a and /mnt

I normally mount the device with the .dmp file (maybe a NFS mount from a remote machine containing the dump) on /mnt
I normally mount the newly created filesystem (slice) on /a

Change directory to /a and ufsrestore the dump.

Hope that helps.
