Recovering from boot disk
failure
VxVM and boot disk failure
Veritas Volume Manager (VxVM) protects systems from disk and other
hardware failures and helps you to recover from such events. Recovery
procedures help to prevent loss of data or system access due to the failure of the
boot (root) disk.
The procedures for recovering volumes and their data on boot disks differ from
the procedures that are used for non-boot disks.
See “Recovery from hardware failure” on page 7.
