Chapter 4
SCSI Drive Addressing
The drives in the Hot Swap Cage are automatically assigned SCSI
addresses by the HP NetServer.
The Hot Swap drive's address is dependent on its position within the
drive cage and the combination of half-height and low-profile SCSI
drives installed. Refer to Figures 4-2 through 4-5 for the automatic
SCSI ID assignments.
The Hot Swap Cage also supports the installation of a Duplex board,
which divides the cage in two equal halves. The only drive addresses
available in this case are 0 through 2. Refer to Figures 4-4 and 4-5 for
duplexed cage drive examples.
The non-hot swap SCSI devices use SCSI IDs from 0 through 15, with
the following restrictions:
a. Narrow SCSI devices must be addressed 0 through 6.
b. Wide SCSI devices may be addressed 0 through 15, except for ID 7,
which is held by the SCSI controller.
The non-hot swap SCSI devices are all connected to the same cable,
which is terminated and connected to one SCSI controller. Each SCSI
device connected to the non-hot swap device connector must have a
unique address.
SCSI Device Installation Order
The Hot Swap Cage's supported hard drive configurations for both HP
NetServer models are shown in Figures 4-2 through 4-5. The arrows
indicate the order of hard drive installation.
Start from the bottom of the Hot Swap drive cage when adding hard
drives in the HP NetServer LC 2000.
If you are using one or more filler panels, insert them at the top of the
cage. These configurations may use filler panels and drive spacers to
close up the front of the Hot Swap mass storage cage. If there are gaps
in the cage, the drives may not receive the proper ventilation and could
suffer thermal damage.
Start from the left of the Hot Swap drive cage when adding hard drives
in the HP NetServer LC 2000r.
If you are using one or more filler panels, insert the panels on the right
side of the drive cage. These configurations may use filler panels and
drive spacers to close up the front of the Hot Swap mass storage cage.
