mirror disk failure

[iaguy]

hpux 10.20. hp 9000 - 715/100. external 9.1GB jamacia box, mirror disk. disks are 12.0 and 13.0.

the boot sector for disk 12.0 (primary) has been corrupted. ISL will not run for disk 12.0. Disk 13.0 seems to be ok except the AUTO file lists disk 12.0 as the boot device. I can execute ISL commands - except boot which starts and fails when it finds "inconsistancies."

Is there a way to correct the errors in the boot sector? How can I boot from disk 13.0?? Can I boot from another disk and mount disk 13.0 to harvest its data?

Hi,you can try the follow command:
#hpux -isl -mx
"-mx " the kernel always uses the accessible disk,regardless of the possibility of corruption;

Sorry!
"#hpux -isl -mx " must be changed to the "ISL>" prompt:
ISL>hpux -isl -mx
OR
ISL>hpux -is -lp;
