Hi:
I restored "/ "from legato backup tape to disk c9t2d0,and added bootable blocks with the command:
/usr/sbin/installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk /dev/rdsk/c9t2d0s0
But it is not bootable, the error message is: can't open kernel/unix.what does it mean?
Thanks
Sally
Hello Sally,
this usually means that the Solaris version/release that you have restored doesn't met the minimum required version - if doesn't contain a suitable kernel to support your hardware.
Eg. your are using a Sun Fire[tm] V240 Server and restored Solaris 8 2/02, but minimum required is Solaris 8 - 12/02.

Hello Sally,
<i>Does it mean if my server crashs, I can't recover the OS from backup tape?</i>
If you are restoring to a different system type eg. backup from Ultra 2 and you restore to an V210, yes !
Later systems require support which was added in the minimum required version.
<i>Is there any way I can recover the OS?</i>
The data e.g. configuration files can be restored.
Unfortunately you didn't mention the type of system you had used for the backup/restore.

My case is: one root disk seems having problem, so SUN support advices to broken the mirror, and uses the second root disk (used as mirror disk before the broken) to restore the "/" from backup tapes. The model of my system is E5500, OS is 5.5.1. I backed up "/" on the system to Legato Networker tape, and restored to same server.
The second root disk has the partitions and bootable blocks,I think the bootable blocks has been overwritten by the restore, that's why I want to add bootable blocks again. I think the Legato Networker tape didn't backup the bootable blocks because we don't use the Disaster recovery Function fo Legato.

Hello,
this is a completely different issue, disregard what I have said about minimum required versions.
You can re-install the bootblock from the Solaris 2.51 CD (that SunOS 5.51) or your first disk (as you mentioned in your first post).
Maybe you can re-post in the <a href="http://supportforum.sun.com/hardware/index.php?t= thread&frm_id=6&rid=23&SQ=5d80ab1bdd9bb006f625ac872b3306 70" target="_blank"><b>Storage</b></a> Forum (while this is a software issue, there are attendees) with a link to this thread.
After closer looking at the error message, the bootblk is and was already present, but the system can't locate the kernel files. Appears to me that the restore didn't went properly.

I checked the Legato backup, I see the following were excluded from "/":
<a href="mailto:root@sun5500" target="_blank">root@sun5500</a>#more .nsr
skip: bin
skip: cdrom
skip: dev
skip: devices
skip: kernel
skip: lost+found
skip: mnt
skip: net
skip: platform
skip: proc
skip: tmp
skip: sbin
It looks the "kernel" was not backed up at all.
