(for 1 way mirroring)
OR
# lvreduce -m 1 -A n -k <LV name> /dev/dsk/cXtXcX <pvkey#>&
(for 2way mirroring)
For example, enter:
# lvreduce -m 0 -A n -k /dev/vg00/lvol4 /dev/dsk/c2t4d0 1&
The following message will appear:
Logical volume /dev/vg00/lvol4 has been successfully reduced.
lvlnboot: Logical Volume has no extents.
NOTE It is important to include the ampersand (&) at the end of the command line.
Otherwise, the
lvreduce process will hang, and you will need terminal control to
negate the command. Once the ‘successfully reduced’ message has been generated,
manually end the process using the
kill -9 command.
Step 1. Use the ps command to find the PID for the lvreduce process.
# ps -ef | grep lvreduce
Step 2. Manually end the process with the Kill -9 command (It may take several minutes for the process to
end.).
# kill -9 <PID>
Step 3. Repeat steps 4 and 5 for all logical volumes.
Step 4. With all logical volumes reduced, now reduce the volume group using the vgreduce command. For
example:
# vgreduce /dev/vg00 /dev/dsk/c2t6d0
CAUTION The vgreduce procedure may take a long time to complete. Do NOT terminate this
process.
Step 5. Update the disk BDRA using the
lvlnboot
command.
# lvlnboot -R
Step 6. Proceed to the HotPlug Hardware Procedure to remove the bad disk drive from the server.
HotPlug Hardware Procedure
CAUTION Disk Drives can be removed or installed with the server still powered on. This is referred to as
a “manual HotPlug”.
To remove a disk drive from the server, perform the following step:
