Try running "fsck -y /dev/vgxp01/rlvxp001".

These errors indicate the file system is bad. You need to attempt to recover it with

fsck -F vxfs -o full, nolog /dev/vg05/rlvol or whatever the logical volume is.

Thank's for all,
Hello Mark and Pete
I run both command but what I recovered is in other directory structure.
No metter,my problem is strange because I have the same problem in other machine, V Class, with the same HP 11.0 OS.
I have configured other file system on XP512 Storage and after some days of properly work I receive the same error.
I check to see if I have patch for XP512 and I have.
Until now I not discover from where I have this problem.

I look forward for your oppinion

Thank's in advance

Is it possible that someone is creating logical volumes using physical volumes on one machine and the same physical volumes on another machine are also being used in a different volume group. THe same physical volumes can have different device names when seen from another host. This is just a possibility.

Remember, if you have to use "pvcreate -f" you probably haven't been as careful as you could!

Questions:
- What FC-HBA are you using? Are you up to patches on your FC subsystem?
- Do you have the latest patches for VxFS, LVM, etc?
- Are you multi-pathing your XP512 LUNs such that the're "visible/accessible" from any FC path/host?
.
Do a clean sweep of critical patches.. use ITRC Custom Patch Manager services to see if you're missing a very critical patch.
