The logical drive configuration screen appears. Span=Yes displays on this screen if you select two or more arrays to span.

The window at the top of the screen shows the logical drive that is currently being configured as well as any existing logical drives. The column headings are:

–LD: The logical drive number

–RAID: The RAID level

–Size: The logical drive size

–#Stripes: The number of stripes (physical drives) in the associated physical array

–StrpSz: The stripe size

–Drive-State:The state of the logical drive

8Highlight RAID and press <Enter>.

A list of the available RAID levels for the current logical drive appears.

9Select a RAID level for the logical drive and press <Enter> to confirm.

See Chapter 3 for an explanation of the RAID levels.

10Set the spanning mode for the current logical drive.

11Highlight Span and press <Enter>. The choices are:

–CanSpan: Array spanning is enabled for the current logical drive. The logical drive can occupy space in more than one array.

–NoSpan: Array spanning is disabled for the current logical drive. The logical drive can occupy space in only one array.

PERC 3 supports spanning of RAID 1 and 5 arrays only. You can span two or more contiguous RAID 1 logical drives into a RAID 10 array, and two or more contiguous RAID 5 logical drives into a RAID 50 array.

For two arrays to be spanned, they must have the same stripe width (they must contain the same number of physical drives) and must be consecutively numbered. For example, assuming Array 2 contains four disk drives, it can be spanned only with Array 1 and/or Array 3, and only if Arrays 1 and 3 also contain four physical drives. If the two criteria for spanning are met, PERC 3 automatically allows spanning. If
