Removing and Replacing Components Individual Component Remove/Replace Instructions WARNING: VGDISPLAY: WARNING: COULDN'T QUERY PHYSICAL VOLUME "/DEV/DSK/cXtXdX" 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 you see these messages, the disk was defective at the time the volume group was activated. Remove the bad disk as described in step 9 of this procedure, then follow the instructions in for replacing the disk and perform the HotSwap Procedure for Unattached Physical Volumes described there. Otherwise, the disk drive became defective after vgchange was run. Proceed to Step 2. Step 2. Display the names of all the logical volumes on this volume group with the vgdisplay command. For example: #vgdisplay /dev/vg00 Step 3. Determine which logical volumes have mirrors with the lvdisplay command. For example: #lvdisplay /dev/vg00/lvol# | grep -ie "LV Name" -e "Mirror" Step 4. Determine the pvkey command status 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 00000 0 00000 current 1 00001 0 00001 current 1 00002 0 00002 current 1 PE2 Status 2 00000 current 00001 current 00002 current Chapter 7 145

WARNING:
VGDISPLAY: WARNING: COULDN’T QUERY PHYSICAL VOLUME “/DEV/DSK/cXtXdX”
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 you see these messages, the disk was defective at the time the volume group was activated.
Remove the bad disk as described in step 9 of this procedure, then follow the instructions in
for
replacing the disk and perform the
HotSwap Procedure for Unattached Physical Volumes
described
there.
Otherwise, the disk drive became defective after
vgchange
was run. Proceed to Step 2.
Step 2.
Display the names of all the logical volumes on this volume group with the
vgdisplay
command. For
example:
#vgdisplay /dev/vg00
Step 3.
Determine which logical volumes have mirrors with the
lvdisplay
command. For example:
#lvdisplay /dev/vg00/lvol# | grep -ie “LV Name” -e “Mirror”
Step 4.
Determine the
pvkey
command status 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
