Mass Storage Guidelines

Read this section prior to installing mass storage drives for a successful
installation.

Selecting SCSI Devices

Hot-Swap
Hot-swap mass storage consists of either low profile (1.0-inch) or half-height
(1.6-inch) drives. For the hot-swap shelves use only HP LVD SCSI 3.5-inch hard
disk drives. HP hot-swap drives come set for LVD SCSI operation and without
device ID or termination. Do not change these settings.
Non-Hot-Swap
For the non-hot swap shelves, use 3.5-inch or 5.25-inch single-ended (SE) SCSI
devices. This bay supports either two half-height or three low profile devices. You
can order HP mounting kits for removable media devices or trays for 3.5-inch
hard disk drives (both low profile and half-height). You may use narrow/wide
SCSI adapters on these devices.

SCSI Termination

The internal SCSI cable for the non-hot-swap bays is terminated. The cable(s) for
the hot-swap storage cage(s) is(are) not terminated. Do not interchange cables.

Hot-Swap Cage Configuration

A low profile drive fits within one slot. HP recommends you start configuring at
slot 1 (the slot nearest the bottom of the cage) to get optimum loading of the bus.
A half-height drive requires most of the space provided by two slots. Use a drive
spacer to close up the remaining space.
Figure 4-2 shows primary cage (SCSI A) and Figure 4-3 shows optional
secondary cage (SCSI B) configurations for the LH 6000r orientation. In
installations where the cage is not fully populated, add drives from the lowest
SCSI address (left most drive position) to the highest.
Figure 4-4 shows the configurations for duplex bus operation in the LH 6000r
orientation. Duplex bus operation requires the addition of the duplexing accessory.
