Planning for hot spare device parity protected disk units

 

Successfully plan how to create hot spare disk units.

In order to use hot spare for your parity protected disk units, the following requirements must be met:

• The disk units must be parity protected.

• The hot spare disk unit must be under the same IOA as the disk units that you want protected.

• The hot spare disk unit must be the same capacity as the failed parity protected disk unit (for SCSI IOAs) or must be the same or larger capacity as the failed parity protected disk unit (for SAS IOAs)."

• When an IOA controls the load source disk unit, the hot spare disk unit must be in a valid load source location. This may require additional planning when using a SCSI IOA since the valid load source locations are typically a subset of the possible disk unit locations within the enclosure. The system will not allow the Start device parity protection with Hot Spare to occur if this requirement is not met.

• The hot spare disk unit must be a non-configured and unprotected disk unit.
