HotPlug Disk Drive Removal (HPUX Systems Only)
VOLUME "/DEV/DSK/cXtXdX"
THE PATH OF THE PHYSICAL VOLUME REFERS TO A DEVICE THAT DOES NOT
EXIST, OR IS NOT CONFIGURED INTO THE KERNAL.
If you are unsure of the status of the vgchange, you may check if this occurred by typing the
vgdisplay command: vgdisplay <VG name>. For example:
# vgdisplay /dev/vg00
If you see these messages, the disk was defective at the time the volume group was activated.
Remove the bad disk as described in the HotPlug Hardware Procedure section, then follow the
instructions in Disk Drive Replacement for replacing the disk and perform the Hot Swap Procedure
for Unattached Physical Volumes described there. Otherwise, your disk drive became defective
after the vgchange and you must continue with step 2 of this section.
Step 2. Display the names of all the logical volumes on this volume group using the vgdisplay command.
For example:
#vgdisplay /dev/vg00
Step 3. Determine which logical volumes have mirrors by using the lvdisplay command. For example:
#lvdisplay /dev/vg00/lvol# | grep -ie "LV Name" -e
"Mirror"
Step 4. Determine the pvkey for the mirrored logical volume, again using the lvdisplay command with the
-k option. Compare the output to the lvdisplay command with the -v option to determine the device
file to pvkey mapping. For example,
# lvdisplay -v -k /dev/vg00/lvol1
