Step 2
• Reduce any logical volumes that have mirror copies on the faulty disk
so that they no longer mirror onto that disk (note the -A n option):
lvreduce -m 0 -A n LV name /dev/dsk/< hard drive >
(for 1-way mirroring)
For our example:
lvreduce -m 0 -A n /dev/vg00/stand /dev/dsk/c2t5d0
lvreduce -m 0 -A n /dev/vg00/swap /dev/dsk/c2t5d0
lvreduce -m 0 -A n /dev/vg00/ /dev/dsk/c2t5d0
The number of logical volumes that this step needs is variable. For
instance, on a mirror of a root disk you should have at least three
logical volumes: /stand (is lvol1), /swap (is lvol2), and / (is lvol3).
Note that if your root mirror disk dies, you need to do the following:
— Follow the procedure in the section "Initial System Loader (ISL)
Environment" in the chapter "Boot Console Handler" in the
Technical Reference. At the Main Menu prompt boot from the
good disk.
— Type y at the Interact with SPL prompt and press
— Type this command at the ISL prompt and press
The -lq option stands for loss of quorum. Once this procedure has
been completed the system will boot.
Step 3
• Replace the faulty 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.
For our example:
ioscan /dev/dsk/c2t5d0
