Corrupt root file system

[johny123]

Dear Friends,

We have a HP 9000 H-40 system which has hpux 11.0 installed on it. The system crashed a few days back and the "/" file system is corrupt. We are booting the system from recovery CD and getting the recovery shell. We want to run "fsck" on root file system but the shell does not recognize the Logical Volume name. Please suggest remedy for this problem.

regards,

Johny

Hello Johny ,

Firstly , it looks like unrecoverable situation .
But try going to LVM mode , rather than using your recovery CDROm .

If the system goes to LVM mode ( ie hpux -lm ) then it means that it can
still detect your stand dir ( ie /dev/vg00/lvol1 or /stand ) & also
an fsck command is successful on /stand dir .

Update me the status on this first . Then we can see if we can proceed
with your recovery .

Hi Omari,

I will try - hpux -lm option. Actually the problem is at a client of our company. They were thinking of reinstalling the system if nothing worked. So, i'll suggest them this solution and will update you about if it worked or not.
Thanks again for the solution.

regards,
Johny

Hi Johny ,

Also a failure in your system may also indicate a
a.) Bad Root Volume group mirrored hard disk .
If yes , then type hpux -lq at the ISL prompt, as
shown below .

ISL > hpux -lq
and see if you can go to the hash prompt( ie # )
