Chapter 6 Installing Mass Storage Devices Table 6-1. Supported SCSI Devices Location Hot-Swap Mass Storage Shelves Non-Hot-Swap Mass Storage Shelves Drive Types 4.2, 9.1, or 18.2 GB Ultra2 7200 rpm or 10K rpm drives (up to 35W power consumption) 4.2 or 9.1 GB Ultra Wide or Single-Ended SCSI Drives, 7200 rpm DAT backup systems or Tape Drives (DLT, DDS, autoloader) SCSI Addressing NOTE Do not set up any devices with SCSI address 7. This address is reserved for the SCSI controller. Hot Swap Drive Cage Addresses The HP NetServer comes with a single hot-swap mass storage cage installed. In the HP NetServer LH 4, the cage is on the lower right front. In the HP NetServer LH 4r, the cage is at the lower left front. The SCSI addressing scheme associated with the hot-swap mass storage cage begins with SCSI address 0, and continues with addresses 1, 2, 3, 8, and 9. You can install a second hot-swap mass storage cage. Addresses in the second cage are independent of the drive addresses in the primary cage. Do not install a narrow SCSI drive in any hot-swap mass storage shelves with an address higher than 6. Narrow SCSI is limited to SCSI addresses 0 - 7, and the NetServer will not be able to communicate with it. Other SCSI Device Addresses SCSI devices installed in the two non-hot-swap shelves next to the flexible drive and CD-ROM drive are attached to the SE SCSI connection, and must use a SCSI address that does not conflict with the SCSI addresses used by drives in hot-swap mass storage shelves. Do not install a narrow SCSI drive in any location with an address higher than 6. Narrow SCSI is limited to SCSI addresses 0 - 7, and the NetServer will not be able to communicate with it. 32
