Disk sparing and relocation management

The hot-relocation feature of VxVM uses spare disks in a disk group to recreate volume redundancy after disk failure.

Checking the number of spare disks in a disk group (vxse_spares)

This "best practice" rule assumes that between 10% and 20% of disks in a disk group should be allocated as spare disks. By default, vxse_spares checks that a disk group falls within these limits.
