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 15 physical disk drives in an array, depending on the RAID level
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
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
