5 Configuring MegaRAID Express 500

Configuring SCSI Physical Drives

SCSI Channel Physical SCSI drives must be organized into logical drives. The arrays and logical drives that you construct must be able to support the RAID level that you select.

Your MegaRAID Express 500 adapter has one SCSI channel.

Basic Configuration Rules You should observe the following guidelines when connecting and configuring SCSI devices in a RAID array:

attach non-disk SCSI devices to a single SCSI channel that does not have any disk drives,

you can place up to eight physical disk drives in an array,

include all drives that have the same capacity to the same array,

make sure any hot spare has a capacity that is at least as large as the largest drive that may be replaced by the hot spare, and

when replacing a failed drive, make sure that the replacement drive has a capacity that is at least as large as the drive being replaced.
