HSD10 Operation
4-18 VAX 4000 Model 108 User Information
Setting HSD10 Device Parameters
Use the following procedure to set new device parameters:
1. At the nodename prompt, enter the parameters you wish to change, as shown in the
following example:
211072> SET CONTROLLER/NODENAME = HSD10
211072> SET CONTROLLER/DISK_ALCS = 10
In this example, the NODENAME has been changed to HSD10 and the DISK_ALCS
parameter set to 10.
2. Enter the SHOW ALL command to display your changed parameters.
3. Reboot the HSD10 adapter to use the new parameters:
211072> RESTART
4. If any SET CONTROLLER parameters were modified (as in this example), reboot the
host systems.
Mapping Devices to OpenVMS Systems
SCSI devices attached to the HSD10 are not automatically made visible to the host, but
must be "mapped" to OpenVMS by the user. This mapping allows translation of physical
device names known by the HSD10, to MSCP/TMSCP device names that are visible at the
host level.
Physical device names follow the format of Dpil orTpil, where D identifies a disk and T a
tape. The other identifiers in the format are p = port, i = SCSI ID, and l = LUN (logical
unit number). In normal HSD10 usage, p is always 1 (specifying the SCSI port), and l is
usually 0.
AUTOCONFIG to Scan SCSI Bus
The first step in device mapping is to scan the HSD10's SCSI bus for attached devices.
This is done by issuing the AUTOCONFIG command as shown. Devices found will be
listed with their physical names:
HSD102> AUTOCONFIG/LOG
