i have hp-ux 10.20 , i have a problem on  file systems when we try to mount them

# mount -a
mount: /dev/vg00/lvuse is already mounted on /users
vxfs mount: /dev/vg00/lvdat is corrupted. needs checking
mount: /dev/vg00/lvlog is already mounted on /inglog
vxfs mount: /dev/vg00/lvol7 is corrupted. needs checking
mount: /dev/vg00/lvol6 is already mounted on /usr
vxfs mount: /dev/vg00/lving is corrupted. needs checking
mount: /dev/vg00/lvol5 is already mounted on /tmp
mount: /dev/vg00/lvol4 is already mounted on /opt
mount: /dev/vg00/lvol1 is already mounted on /stand

i did fsck to the failed mount file systems and i get the following error

# fsck /dev/vg00/lvdat
\log replay in progress
vxfs fsck: fsck read failure bno = 772, off = 0, len = 32768

>what should I do to remount these file systems

Looks like you have I/O errors on them.  Time to get out your backups.

You might be able to mount them read only to get some files off.

i need to try to make them work without retraining to backup , i have old backup is there is a way to do this , also how to mount them in read only mode and copy the data from them

# fsck -o full,nolog
