fsck error: Unable to invoke hfs-specific module ......

[mooi-kuan]

I have the following error message when I tried to fsck a HPUX 10.2 box after a power failure.

Error:
Unable to invoke hfs-specific module for the command fsck at /sbin/fs/hfs/fsck
File or directory not found.

Is the corruption was due to a patch problem ?
Here is the output of what /sbin/fs/hfs/fsck on a similar machine.

Please help me on how to recover this. Thank you.

Hi !

If You have an older version use recovery CD-ROM, or a newer one use Core-OS CD.
Run recovery shell and do fsck.

Hello,

The Response Center has written several documents about recovering a system where boot-up issues are causing trouble. The articles are located in the customer-accessible database in itrc.hp.com.

Sandor mentioned the use of the Support/Recovery or Install CD. The articles listed below tell which you will need to use depending on your version of operating system.

Once booted on the support/recovery CD, doing "chroot_lvmdisk" will automatically fsck both / and /stand. It will also mount both and "change root" down to the disks' / directory, where you can inspect your file systems.

Though the support media has a limited number of commands to work with, it has access to frecover, should you need to restore files from an fbackup tape. The articles have a few examples on techniques.

A word to the wise - the recovery/discovery process may take much more time than the time to reinstall and configure the O.S. Set a deadline for your support/recovery CD efforts, and if you are not making "reasonable" headway, reinstall & reconfigure, or if you did a make_recovery tape - use it.

Depending on the version of O.S. - refer to one of these two documents:
How do I boot my system from Support Media on 10.X ? (OZBEKBRC00000581)
How do I boot my system from Support Media on 11.00 ? (OZBEKBRC00000582)
