The Question is: Is there a way in vms to remove or hide the non exsistant dqa1:, dqb0:, and dqb1: ide devices? I understand that they exist for hot plug purposes, but we will not hot plug these devices. The Answer is :
The effort of disabling the IDE device controller configuration
process is likely more work than it is worth -- by the time OpenVMS
learns the IDE device is not available, backing out and removing the
references is difficult. Accordingly, you would have to disable the
entire autoconfiguration process, and then manually autoconfigure
excluding the specified devices. (This may or may not work.)
Hot-swapping of IDE is not available on any OpenVMS system that the
OpenVMS Wizard is presently (as of August 2001) aware of.
Alternatively, assuming that this is a device naming collision in an
OpenVMS Cluster, you can enable and use port allocation classes with
the IDE devices and avoid this device name collision.
* In SYSGEN, make sure DEVICE_NAMING is set to 1, and
ALLOCLASS is set to a non-zero value.
* Create a file named SYS$SYSTEM:SYS$DEVICES.DAT, that
specifies a Port Allocation Class of 0 for the two DQ
controllers (DQA and DQB).
You can either edit this file to add the information manually, or update
this file automatically by using the following commands at bootstrap time:
SYSBOOT> SET /CLASS DQA 0
SYSBOOT> SET /CLASS DQB 0
Following is a sample SYS$SYSTEM:SYS$DEVICES.DAT file (for node ACORN::):
[Port ACORN$DQA]
Allocation Class = 0
[Port ACORN$DQB]
Allocation Class = 0
This procedure causes all DQ devices to be named in the following format,
thus allowing for unique device names across the cluster:
nodename$DQxn:
where:
nodename is the system name
x is either A or B
n is either 0 or 1
