Recovering a system by booting from a VxVM root disk mirror

If a failed primary boot disk is under VxVM control and is mirrored, it must be replaced.

 To recover a system by booting from a VxVM root disk mirror

1. Replace the failed 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.
