Recovery from a Failed VxVM Boot Mirror Disk
If a failed primary boot disk is under VxVM control and is mirrored, follow these steps to
replace it:
Step 1. Replace the failed boot disk. Depending on the system hardware, this may require you to
shut down and power off the system.
Step 2. Boot the system from a mirror of the root disk, and use the following command to
initialize the replacement disk:
# /etc/vx/bin/vxdisksetup -iB rootdisk_access_name privlen=1024
Where rootdisk_access_name is the disk access name of the root disk (for example,
c0t0d0).
Step 3. Run the vxdiskadm command, and use option 4 (Replace a failed or removed disk)
to define the newly initialized disk as the replacement for the root disk (usually
rootdisk01).
Step 4. Run the vxrecover command, and allow the plexes on the replacement root disk to be
completely resynchronized.
