BAD SUPER BLOCK: MAGIC NUMBER WRONG
I found the Hp-ux recovery cd and I try to use it to try to recover our system from 9245xb Pdt
VFS_MOUNTROOT failed.
But when recovery program reach the fsck utility, I get this message BAD SUPER BLOCK: MAGIC NUMBER WRONG /dev/rdsk/c0t8d0s1lvm and the utility stop saying to try the -b option.
The same message trying the -b option.
Also because of my low skill on hp-ux 10.20, now I don't what to try.
Any help ? Thanks a lot.
Hp-ux 10.20 running on an Hp 9000 d270, two 4.3 gb differential scsi drive.

Re: BAD SUPER BLOCK: MAGIC NUMBER WRONG
A list of alternate super blocks is stored in /etc/sbtab.
If somehow you have the contents of this file, u can use -b option to specify alternate super-block and then should be able to complete fsck.
