About Cabling the Secondary Cage

The HP NetServer is normally shipped with the primary mass storage cage
connected to the SCSI A connector on the I/O baseboard. The secondary mass
storage cage can be connected to the SCSI B connector on the I/O baseboard if
that connector is unused. The hot-swap mass storage cages cannot be daisy-
chained; that is, they cannot be connected to each other or to other mass storage
devices.
NOTE Do not use a terminated SCSI cable on either hot-swap mass
storage cage.
The SCSI A and SCSI B channels on the I/O baseboard can both be set to
integrated HP NetRAID (RAID) or LVD SCSI (non-RAID) operation, but both
channels must operate in the same mode, RAID or non-RAID. For more
information on RAID, see Chapter 3.
l
To operate both mass storage cages as RAID, connect the secondary
mass storage cage to the SCSI B connector on the I/O baseboard. Refer to
"Cabling to I/O Baseboard SCSI B" below for instructions.
l
To operate both mass storage cages as non-RAID, connect the
secondary mass storage cage to the SCSI B connector on the I/O
baseboard. Refer to "Cabling to I/O Baseboard SCSI B" below for
instructions.
l
To operate one mass storage cage as RAID and the other as non-
RAID, only connect one cage to the I/O baseboard. Install an accessory
SCSI host bus adapter or an HP NetRAID series adapter to control the
mass storage cage not connected to the I/O baseboard.
NOTE If a duplex board is installed in the primary or secondary mass
storage cage, refer to the HP NetServer Duplex Kit Installation
Guide for cabling information.
