HSD10 Operation
VAX 4000 Model 108 User Information 4-9
1. Select an unused SCSI ID for the HSD10 DSSI-to-SCSI bus adapter.
2. Refer to Figure 4-1 and Table 4-4 to locate the SCSI ID switches on the node
configuration switchpack and determine how they are to be set.
3. Using a small blade screwdriver or similar tool, set the switches to the SCSI ID
number selected in Step 1.
Applying Power to the HSD10
__________________________ Note _____________________________
HSD10 controllers ordered in preconfigured systems are shipped with SCSI and
DSSI ports Enabled. Non-preconfigured HSD10 controllers require enabling of ports
through the adapter's serial communications port.
____________________________________________________________
Apply power to the HSD10 DSSI-to-SCSI bus adapter as follows:
1. Place the power switch on the VAX 4000 Model 108 system in the on position.
2. At the system console prompt, enter the console command SHOW DEVICE on the
OpenVMS VAX system to verify that the HSD10 DSSI node address is on-line to the
host system.
Setting Parameters for the HSD10 DSSI-to-SCSI Bus Adapter
The OpenVMS Diagnostic and Utility Protocol (DUP) utility provides a gateway to
modifying HSD10 DSSI-to-SCSI Adapter configuration. The DUP utility can be run from
either the system console or from the OpenVMS system prompt. Through this on-board
firmware command utility, you can set device parameters including node name, system ID,
disk and tape allocation classes, and performance optimization parameters. It also can be
used for device formatting and qualification and to access device information.
Once a DUP connection to the HSD10 DSSI-to-SCSI bus adapter is established, the
onboard PARAMS configuration utility is used to set and show HSD10 and device
parameters. The section on HSD10 Command Utility Maintenance Operations contains
procedures for using the HSD10 onboard device and diagnostic utility during normal
operation of the subsystem.
