Use Hot Spare devices
If a member of a virtual device becomes degraded
or faulted, you lose some redundancy in your
VTL until a new member is rebuilt into the VTL.
However, Hot Spare devices may be designated
as replacements for faulted devices without
intervention by you or a host.
Note
JBOD and RAID Level 0 groups do not provide
redundancy, making Hot Spare devices
unnecessary.
The ATTO FastStream VT 5300 replaces
degraded or faulted virtual devices in VTL
without intervention by you or a host if you set up
a pool of Hot Spare devices of different sizes
appropriate for your VTL.
Note
Block devices in the Hot Spare
pool should be of appropriate size
to the RAID Group so that smaller
block devices are not replaced by
much larger Hot Spare devices.
When the ATTO FastStream VT 5300
detects a faulted device, the Controller
searches the Hot Spare pool for the
smallest block device of sufficient
size to substitute for the faulted drive.
The FastStream VT 5300 replaces the
faulted device with the device from
the Hot Spare pool.
The FastStream VT 5300 begins an
automatic rebuild of the VTL.
Note
Hot Spares may be set up by the FastStream
VT 5300 automatically depending on your
choices during initial setup.
