Hello,
I am trying to recover froma crashed disk backed up on a Netra X1 to
a SunFire V100.
I have a complete system backup that is done with Legato Networker. I have
setup a network boot using Solaris 8 2/02 software (the same version
installed on the X1).
I have run the format utility and successfully recreated the exsiting
partitions. I have fsck'ed the partitions and created the bootblk on the
/dev/rdsk/c0t2d0s0 slice.
After mounting /dev/dsk/c0t2d0s0 to /a, I have then mounted the other
relevant partitions e.g.
/dev/dsk/c0t2d0s3 /a/var
/dev/dsk/c0t2d0s5 /a/opt
/dev/dsk/c0t2d0s6 /a/usr
I have then restored the data to the relevant slices.
Before rebooting, I have updated the vfstab and the mnttab in /a/etc to
reflect the new target address of 2 (was 0).
When I reboot, I get an error message telling me that /usr is not available
and is corrupt or offline. It can't run fsck and then dumps me to the 'ok'
prompt.
When I do a 'boot cdrom -s', and then manually mount the partitions under
/a, I can do this no problem and all of the data exists (and /a/usr mounts
successfully).
I understand that the directory structures don't match, so I have also
copied /tmp/dev and /tmp/devices and /tmp/root/etc/path_to_inst to /a/dev,
/a/devices, and /a/etc respectively and then done a boot -rv.
Unfortunately, I still get the error message that /dev/dsk/c0t2d0s6 canot be
mounted and the boot fails, dropping me to the 'ok' prompt and suggesting a
'boot -b' to fix the problem. Which, incidentally, also doesn't work!
Can anyone shed anymore light on this problem.
Regards.
