About hot-relocation

Hot-relocation automatically restores redundancy and access to mirrored and RAID-5 volumes when a disk fails. This is done by relocating the affected subdisks to disks designated as spares and/or free space in the same disk group.

The hot-relocation feature is enabled by default. The associated daemon, vxrelocd, is automatically started during system startup.

Follow these recommendations:

• Leave the VxVM hot-relocation feature enabled to detect disk failures automatically. It will notify you of the nature of the failure, attempt to relocate any affected subdisks that are redundant, and initiate recovery procedures.
• Configure at least one hot-relocation spare disk in each disk group. This will allow sufficient space for relocation in the event of a failure.

If you decide to disable hot-relocation, prevent vxrelocd from running after you load the VxVM software. See the section "Modifying the behavior of Hot-Relocation" in Chapter 9 of the VERITAS Volume Manager Administrator's Guide for details.
