Figure 80. Rebuild Settings in Information View.

Right-click on the Controller icon and look into Information View. Check the respective boxes to enable these features:

Enable Hot Spare Disk – Enables a spare drive not assigned to the array to automatically replace a failed drive in the array. You must also enable Auto Rebuild for this feature to be effective.

Enable Auto Rebuild – Enables automatic rebuilding of a fault-tolerant (RAID 1, 0+1 and 5) array when it goes Critical.

Enable Hot Swap Disk – Allows you to replace a faulty disk drive without shutting down the system. This feature works with an externally replaceable disk drive enclosure such as the Promise SuperSwap.

Rebuild Setting – Allocates system resources between rebuilding the array and responding to read/write commands from the computer system.

A High setting assigns most of the system resources to rebuilding. Rebuilding goes faster, restoring redundancy sooner but read/write requests are handled slower.

A Low setting assigns most of the system resources to handling read/write requests. Read/write requests are handled at nearly normal speed while the rebuild takes longer.
