Installing A Scsi Hard Disk Drive - IBM LS20 - BladeCenter - 8850 Installation And User Manual

Installing a SCSI hard disk drive

The blade server has two connectors on the system board for installing optional
Ultra320 SCSI hard disk drives.
All Ultra320 SCSI connectors are on the same bus. Depending on the blade server
model, at least one SCSI hard disk drive might already be installed. If the blade
server is equipped with one SCSI hard disk drive, you can install an additional SCSI
hard disk drive. These two SCSI hard disk drives can be used to implement and
manage a redundant array of independent disks (RAID) level-1 array. See
"Configuring a SCSI RAID array" on page 39 for information about SCSI RAID
configuration.
The following illustration shows how to install a SCSI hard disk drive.
