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.
