Recovery by Booting from a VxVM Root Disk Mirror

If a failed primary boot disk is under VxVM control and is mirrored, follow these steps to replace it:

1. Replace the failed boot disk. Depending on the system hardware, this may require you to shut down and power off the system.
2. Boot the system from a mirror of the root disk, and use the vxrootmir command to initialize and mirror the volumes on the new root disk:
   # /etc/vx/bin/vxrootmir -v -b new_root_disk_access_name

   The -b option sets the newly mirrored disk as the alternate boot disk in the NVRAM. The -v option gives progress indications as each volume is being mirrored.
