DF Disk Module - Is the Volume Group or Physical Volume Group Active? (HP 9000 Series
800 with Strict Mirroring)
Use this procedure to determine if the volume group and physical volume group is active:
1. At the host console type:
# vgdisplay <VG name>
If you followed the example under “Example of a Disk Module Failure”, the host will display:
# vgdisplay /dev/vg00
If the volume group is not active, the host will display:
# vgdisplay: volume group not active
# vgdisplay: cannot display volume group <VG name>
2. If the disk was defective when vgchange was executed, the following messages will be displayed:
VGDISPLAY:WARNING: COULDN'T QUERY PHYSICAL VOLUME “/DEV/DSK/c2t4d0”
THE SPECIFIED PATH DOES NOT CORRESPOND TO PHYSICAL VOLUME
ATTACHED TO THE VOLUME GROUP
VGDISPLAY: WARNING: COULDN'T QUERY ALL OF THE PHYSICAL VOLUMES
• If the message above displays, the physical volume is not active. Refer to “DF Disk Module
Replacement/Recovery Procedure for Unattached Physical Volumes (HP 9000 Series 800 with
Strict Mirroring)”.
• If the message above does not display, the physical volume is active. Refer to “DF Disk Module -:
Is the Physical Volume Attached? (HP 9000 Series 800 with Strict Mirroring)”.
