Installing and Removing Hot-Plug SCSI Hard Drives
NOTE:
SCSI hot-plug functionality is available only when SCSI RAID is used. See the SCSI RAID
controller's documentation to verify that its configuration supports hot-plug SCSI hard drives.
The drive bays in a system with an optional SCSI backplane board provide space for up to six
1-inch hard drives. The hard drives plug into the SCSI backplane board, which is connected to a
controller on the system board or to a RAID controller card. See Figure 7-11 and Figure 7-12.
