Hello Noble Sebastian.

please check your /var/adm/syslog.log file to see if there are any hardware errors

[Fabian Briseño]

you caould also use vgdisplay -v vg03 to see more information

Hi

You can see by using vgdisplay -v

also, find the detail from /etc/lvmpvg

Good Luch !

Hi Noble,

You can use vgdisplay -v , and check for the "PV status" of each disks in that vg. "pv status " should show "available" staus.

Also you can use "ioscan -fnC disk" to find out the status of each disk.

Regards !

hi noble,

First check your syslog for any errors,
type the command strings /etc/lvmtab this will show the pvs corresponding vg. then check the pv which are belogs to vg03 are claimed. and also check for the pv available status in vgdisplay -v vg03

Hi;

Please check /var/adm/syslog/syslog.log output
and /var/adm/messages output
or
#dmesg

To check PV belongs to vg03

#vgdisplay -v vg03

or

#strings /etc/lvmtab |more

To check the status of PV

dd if=/dev/null of=/dev/rdsk/cxtxdx bs=1024

if it is a ECM storage, there are many other command to check the status of PV

Check syslog for failed disks.

Check vgdisplay -v vg03 for any unavailable physical volumes, they will have status unavailable.

If you have mirrored the logical volumes living up on the unavailable physical volume (you will see logical volume status as available/stale there instead of available/syncd), then reduce the mirror and replace the disk.

If you don't have mirrored logical volumes, then you will need your backups to restore data to new replaced disks on all logical volumes, where that unavailable physical volume belongs to.
