Drive Bay Shelves; Boot Priority - HP NetServer LC 2000r Installation Manual

Chapter 4

Drive Bay Shelves

The non-hot swap drives include the IDE CD-ROM and the 3.5 inch flexible disk
drives which are standard for all HP NetServer models (LC 2000/2000r) and ship
with each unit. The two empty drive shelves beneath the CD ROM drive support
other non-hot swap SCSI devices, such as hard drives (3.5-inch or 5.25-inch), tape
back-up devices, or other HP-tested (LVD or SE) SCSI accessories.
The system chassis ships with a Hot Swap Mass Storage cage supporting up to six
low-profile Hot Swap hard drives or three half-height Hot Swap hard drives.

Boot Priority

This section details the HP NetServer's boot order by highest to lowest priority.
The on-board SCSI controller has two channels, A and B. Channel A is typically
used to control the Hot Swap SCSI drives. Channel B is typically used to control
the internal non-hot swap SCSI drives. On each SCSI channel, the NetServer
scans for a boot device starting at device ID 0 and proceeds up from there.
The HP NetServer's boot order (BIOS search order for a boot device) should be
considered, when connecting cables from the on board SCSI channels. A SCSI
drive's boot priority is set by the drive's location in the boot order. See Figure 4-1.
