Solaris 9 HDD Mounting 1

[parrysands]

History...I am not a Solaris guy. I know very little about any of it. My boss deleted files from a HDD on a Solaris 8 drive. After reboot, system will not boot.

I have the files to put back on the HDD, but cannot access it to do so.

What I have done. On a Netra 1125, I installed Solaris 9, and have a functional system, with Webmin and SSH access. I need to add the old drive, somehow mount it, and copy the files back to it. I have tried many things I have found on the internet, but so far nothing has worked. I could really use some help here.

Thanks,
Parry


Here is a paste of what I have tried:

screen not found.
Can't open input device.
Keyboard not present. Using ttya for input and output.

Netra t 1120/1125 (UltraSPARC-II 440MHz), No Keyboard
OpenBoot 3.23, 512 MB memory installed, Serial #13155783.
Ethernet address 8:0:20:c8:bd:c7, Host ID: 80c8bdc7.

I believe t6 might be your cdrom drive.

Solaris does not rebuild the device tree on device insertion.

Run "devfsadm -C disk"

Then run "echo | format" to see if the drive is seen.

If you see the new drive, then remember the value X to be used next.

If it was a root drive, most likely root was /dev/c0tXd0s0.

dump the partition table using prtvtoc:

prtvtoc /dev/rdsk/c0tXd0s2

If it was a root drive, I would fsck the root partition only, mount it, and inspect the old vfstab:

fsck /dev/rdsk/c0tXd0s0
mount /dev/dsk/c0tXd0s0 /mnt
cat /mnt/etc/vfstab

Remember here that the special file (/dev/dsk/c*) is from the old system, it DOES NOT correspond to your running system. You just want to figure out the partitioning.

Check to see if there is a separate /, or /usr (prtvtoc previously will also tell you)

If it was root stuff that was blown away, then you can restore it now. Most likely a boot problem would
only be a corrupted root or /usr (if one exists)

If there is a separate /usr (indicated by /mnt/etc/vfstab)
then you need to fsck that also and mount it (provided the files to be restored are on it.

Once down, unmount everything you mounted.
Once everything is unmounted, rerun devfsadm -C disk.
