My Ultra 5 (Solaris 10) is now unbootable, with the OBP failing with error "trap 3e" When it tries to boot from disk.
Disk is a Maxtor 80GB IDE, and was working previously.
I've booted to cdrom and run "Format" from Single user, but when I try to read the disk, it just core dumps.
I have no reason to believe this disk is bad.
Can anyone offer any guidance on troubleshooting this?
Thank you in advance,
Akbar.
This error is caused by a bad super block on the boot disk.
Boot CD-ROM in single user mode.
# fsck /dev/rdsk/<device>
This may report a super-block error.
# newfs -N /dev/rdsk/<device>

Your output will not be the same, but the list of numbers is the important bit.
fsck -o b=<altblock> /dev/rdsk/<device>
Where <altblock> is one of the numbers in the list ( you may need to do this several times with different superblocks, if so choose one from the start one from the middle and one from the end )
/usr/sbin/installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk /dev/rdsk/<device>
And reboot.
Reborg, thank you for your response. Unfortunately, I was not able to resolve my issue using the information provided. At a certain point it became easier to reinstall the OS.
Thank you for your assitance though
