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.
