Configuring SCSI Physical Drives

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.

Observe the following guidelines when connecting and configuring SCSI devices in a RAID array:

•You can place up to 32 physical disk drives in an array.

•Include all drives that have the same capacity in the same array. If the drives are not the same size, the array uses the size of the smallest drive and the same amount of space on the other drives to construct the arrays.

•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.

•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.

Current Configuration

Your PERC 3 card has one (SC), two (DC, DCL), or four channels (QC), depending on which card you have. Use Table 7-1 to list the devices that you assign to each SCSI ID for SCSI Channel 0.
