mode management feature. Warning messages are sent out periodically
while the RAID array is degraded.

Enable Global Spares: Allow RAID arrays defined in the system to share
spare drives. If this option is disabled, a RAID array can only use a spare that
has been added to that particular array. If this option is enabled, spare
drives added to one RAID array may be reallocated by the NSS to another
RAID array.
For example, if RAID A is a two-drive RAID1 that is not degraded and RAID B
is a degraded two-drive RAID1, if you add a spare drive to RAID A, the NSS
automatically +gives the spare drive to RAID B to enable RAID B to resync.
This option is only relevant when you use network disks (through storage
virtualization). A system limited to local disks lets you only build up to two,
two-disk RAID arrays, but have no spares.
If you make changes to any of the storage options, click Update.
