Completing this procedure causes HSJ or HSD30 controller-attached disk drives

to be recognized as supported device types.

For the OpenVMS VAX Version 6.0 operating system, the AUTOGEN.COM DCL

procedure does not support device types above 137 although HSX00 and HSX01

are properly deﬁned in the speed list. To circumvent this problem, perform the

following steps:

1. Make a copy of the AUTOGEN.COM DCL ﬁle in case restoration of the

original state is required.

2. Edit the AUTOGEN.COM ﬁle. Change the value 137 in the following

statement to 142.

$ IF (temp .LE. 137) .AND. (temp .GE. 1) -

3. Run the AUTOGEN program.

This change allows AUTOGEN to run successfully against HSJ or HSD30

controller-attached disk drives to be used as system disks.

Note

OpenVMS VAX Version 6.1 or later software does not require

modiﬁcations to the AUTOGEN.COM ﬁle.

Note

The HSOF supports a controller-based preferred path feature for dual-

redundant array controller conﬁgurations. Refer to Section 5.2.5.
