Property Definition
Patrol Read Rate Displays the percentage of system resources dedicated for running the Patrol Read
operation. Patrol Read Rate changes the amount of system resources assigned for the
patrol read task. The Patrol Read Rate can be configured between 0% and 100%, where:
• 0% — indicates the lowest priority for controllers and has the least impact on the system
performance.
• 100% — indicates the highest priority for controllers and has a greater impact on the
system performance.
Patrol Read Iterations Displays the number of Patrol Read Iterations. For more information about patrol read, see
Setting The Patrol Read Mode.
Cluster Mode Indicates whether the controller is part of a cluster configuration.
Persistent Hot Spare Displays if the hot spare is persistent. The possible values are:
• Enabled — The slot corresponding to the hot spare drive is persistent. Any drive in the
slot functions as a hot spare if the drive is qualified to be a hot spare. If the drive contains
foreign data, it is overwritten.
• Disabled — The slot corresponding to the hot spare drive is not persistent. If the drive is
removed from the slot and any drive is inserted, the slot stops functioning as a hot spare.
You need to manually assign the drive as a hot spare again.
