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.
See “Administering hot-relocation” on page 369 for information on managing the pool of
spare disks.
Hardware failures
Checking for disk and controller failures (vxse_dc_failures)
Rule vxse_dc_failures can be used to discover if the system has any failed disks or
disabled controllers.
Rootability
Checking the validity of root mirrors (vxse_rootmir)
Rule vxse_rootmir can be used to confirm that the root mirrors are set up correctly.
System name
Checking the system name (vxse_host)
Rule vxse_host can be used to confirm that the system name in the file
/etc/vx/volboot is the same as the name that was assigned to the system when it
was booted.
