In the following example, SCSI IDs 0 and 5 are being used: >>>SHOW CONFIG DEVNBR DEVNAM INFO _____________________________________________ 10 SCSI OK 0--RZ24 5--TZK10 Make a note of the SCSI IDs of your devices. Refer to Figure 1 to choose a SCSI setting for your drive. Digital recommends SCSI settings 0, 1, 2, and 3 for fixed disk drives. Each device must have a unique SCSI ID. Never set two or more devices to the same SCSI ID; the system will not be able to communicate with the devices. ------------------------------------------------------------ SCSI ID 6 Reserved ------------------------------------------------------------ Do not use SCSI ID 6 for your drive. It is reserved for the controller. ------------------------------------------------------------ 2 The RZ26B Fixed Disk Drive Figure 1 SCSI Settings on the RZ26B Fixed Disk Drive Installing the Drive Follow the instructions in the VAXstation 4000 Options Installation Guide to install this drive. 3 The RZ26B Fixed Disk Drive Verifying the Installation Enter the SHOW CONFIG command to verify that your installation was successful. >>>SHOW CONFIG DEVNBR DEVNAM INFO _____________________________________________ 10 SCSI OK 0--RZ24 2--RZ26B 5--TZK10 In this example the RZ26B drive was set to SCSI ID number 2. ------------------------------------------------------------ RZ26B Fixed Disk Drive Specifications Capacity Table 1 provides the capacity specifications for the RZ26B fixed disk drive.
