fsck! How to run Full File System Check

Dear all

I am new for HP-UX.
I have HP rp2470 running HP-UX 10.x
When i run fsck in a root, the output is as below:

Code:
#:root> fsck
fsck: /dev/vg00/rlvol1: mounted file system

continue (y/n)? y
** /dev/vg00/rlvol1
** Last Mounted on /stand
** Phase 1 - Check Blocks and Sizes
** Phase 2 - Check Pathnames
** Phase 3 - Check Connectivity
** Phase 4 - Check Reference Counts
** Phase 5 - Check Cyl groups
45 files, 0 icont, 38040 used, 45693 free (77 frags, 5702 blocks)
vxfs fsck: /dev/vg00/lvol3 is currently mounted
vxfs fsck: /dev/vg00/lvol4 is currently mounted
vxfs fsck: /dev/vg00/lvol6 is currently mounted
vxfs fsck: /dev/vg00/lvol7 is currently mounted
vxfs fsck: file system had I/O error(s) on meta-data.
log replay in progress
full file system check required, exiting ...
vxfs fsck: /dev/vg00/lvol5 is currently mounted


Then if i run fsck -y, the output as below:

Code:
#:root> fsck -y
fsck: /dev/vg00/rlvol1: mounted file system
vxfs fsck: /dev/vg00/lvol3 is currently mounted
vxfs fsck: /dev/vg00/lvol4 is currently mounted
vxfs fsck: /dev/vg00/lvol6 is currently mounted
vxfs fsck: /dev/vg00/lvol7 is currently mounted
vxfs fsck: file system had I/O error(s) on meta-data.
log replay in progress
pass0 - checking structural files
pass1 - checking inode sanity and blocks
vxfs fsck: fsck read failure bno = 1566, off = 0, len = 8192
file system check failure, aborting ...
vxfs fsck: /dev/vg00/lvol5 is currently mounted

Plz help me explain these output and tell me How to run a full file system check to correct this I/O error(s) on meta-data as above.

Thanks for your support

Running fsck on mounted filesystems is not recommended. If you do need a full fsck, umount the filesystem first. If it is one of the system required filesystems (such as /var), shutdown the system, boot to single user mode, then run fsck on all the filesystems and then reboot to full multi-user mode.

When running the full fsck, the command to run is "fsck -o full -y /dev/..."

fsck -o full! Error message

Thanks blowtorch!

I have tried to run fsck -o full and there is a error message like the following:

Code:
#:root> fsck -o full /dev/vg00/lvol8
vxfs fsck: file system had I/O error(s) on meta-data.
log replay in progress
pass0 - checking structural files
pass1 - checking inode sanity and blocks
vxfs fsck: fsck read failure bno = 1566, off = 0, len = 8192
file system check failure, aborting ...

Could you plz tell me what is the meaning of the above out put? And How to fix it?

Thanks a lot
