seeing strange LVM message in "dmesg"

[Marc Ahrendt]

not sure how to resolve the following on an old HP-UX 10.20 system:

...
Logical volume 64, 0x3 configured as ROOT
lv_readvgdats: Could not read VGDA 2 header & trailer from disk H/W path 2/0/1.6.0 (error = 5)
Logical volume 64, 0x2 configured as SWAP
...

the disk itself seems OK, just wondering if there was a LVM command to refresh this part of the disk ...or something

Are there any other messages in syslog ?

thx tal ...i had already reviewed that post (should have mentioned that since it was the only one i had found in the forums). the difference with that post and my system is that the disk appears to be OK and there are no messages of concern in the syslog.log.

it still may possibly be a disk issue, but wondering if the was a way to repopulate that VGDA area ("lvlnboot -R"?) and test by rebooting again. basically the system is OK except for me noticing that "lv_readvgdats" entry in the early boot process

A vgcfgrestore should restore the LVM metadata. You should then do a mkboot, a mkboot -a, and an lvlnboot -R.

This procedure is not without risk but a vgcfgrestore should rewrite the VGRA.
