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 . 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 --- Logical volumes --- LV Name /dev/vg00/lvol1 VG Name /dev/vg00 LV Permission read/write LV Status available/syncd Mirror copies 1 Consistency Recovery MWC Schedule parallel LV Size (Mbytes) 256 Current LE 64 Allocated PE 128 Stripes 0 Stripe Size (Kbytes) 0 Bad block off Allocation strict/contiguous IO Timeout (Seconds) default --- Distribution of logical volume ---PV Name LE on PV PE on PV /dev/dsk/c1t6d0 64 64 /dev/dsk/c2t6d0 64 64 --- Logical extents ---LE PV1 PE1 Status 1 PV2 PE2 Status 2 00000 0 00000 current 1 00000 current 00001 0 00001 current 1 00001 current 00002 0 00002 current 1 00002 current 00003 0 00003 current 1 00003 current 00004 0 00004 current 1 00004 current 00005 0 00005 current 1 00005 current 00006 0 00006 current 1 00006 current 00007 0 00007 current 1 00007 current 00008 0 00008 current 1 00008 current (etc.) # lvdisplay -v /dev/vg00/lvol1--- Logical volumes ---LV Name /dev/vg00/lvol1VG Name /dev/vg00LV Permission 238 Chapter

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
