Compaq Infortrend manual Assign Spare Drives, Logical Drive Assignments, Disk Reserved Space

Assign Spare Drives:

You can add a spare drive from the list of the unused drives. The spare chosen here is a Local spare and will automatically replace any failed drive in the event of drive failure. The controller will then rebuild data onto the replacement drive.

Alogical drive composed in a none-redundancy RAID level (NRAID or RAID 0) does not support spare drive rebuild.

Disk Reserved Space

The reserved space is a small section of disk space formatted for storing array configuration and RAIDWatch program. Do not change the size of reserved space unless you want your array to be accessed by controllers using older firmware.

Logical Drive Assignments:

If you use two controllers for a dual-active configuration, a logical drive can be assigned to either of the controllers to balance workload. The default is primary controller, press [ESC] if change is not preferred. Logical drive assignment can be changed any time later.

Write Policy

This sub-menu allows you to set the caching mode for this specific logical drive. “Default” is a neutral value that is coordinated with the controller’s current caching mode setting, that you can see bracketed in the write policy status.
