vgdisplay errors

[mjos]

Hi,

I am seeing the below errors when I do a vgdisplay on a particular vg.
However the vg is online & the filesystem is mounted & accessible.
can a vgscan -a after moving the lvmtab file get rid of these errors. Do I need to activate the VG after doing a vgscan (vgchange -a y )? Can the vgscan be done online without affecting the application or the db?
Please help.

All device files point to LUN3 (?); check if the LUN still exists and is accessible.

Please send output of following;
1)strings /etc/lvmtab
2)ioscan -fnC disk

You can activate the VG
#vgchange -a y vg_name
It will not have any impact on running system. It will attach all PV if anything is missing.
