C-14 Appendix C

HotSwap Disk Bay (D Class Only)

# lvreduce -m 1 -A n BB LV name EB /dev/dsk/cXtXdX for 2 way mirroring

For our example:

# lvreduce -m 0 -A n /dev/vg00/lvol4 /dev/dsk/c2t4d0

# lvreduce -m 0 -A n /dev/vg00/lvol5 /dev/dsk/c2t4d0

Step 3

• Replace the faulty disk. Please refer to the appropriate administration guide for

instructions on how to replace the disk.

•Do an ioscan on the replaced disk to insure that it is accessible and also as a double

check that it is a proper replacement (see Note 3 above).

For our example:

# ioscan /dev/dsk/c2t4d0

Step 4

• Restore the LVM configuration/headers onto the replaced disk from your backup of

the LVM configuration:

# vgcfgrestore -n BB volume group name EB /dev/rdsk/cXtXdX

• where X is the Logical unit number of the disk that has been replaced.

For our example:

# vgcfgrestore -n /dev/vg00 /dev/rdsk/c2t4d0

Step 5

• Attach the new disk to the active volume group with the vgchange command.

# vgchange -a y BB volume group name EB

For our example:

# vgchange -a y /dev/vg00

Step 6

• If this disk is not a mirror of a root disk, then skip this step.

•The mkboot command must be run.

For our example:

# mkboot /dev/rdsk/c2t4d0

• After running the mkboot command, do an lvlnboot -R to relink the replaced disk into

the Boot Data Reserved Area of all the Physical Volumes in the Volume Group.
