Compaq StorageWorks HSG60 ACS Solution Software V8.6 for Compaq Tru64 UNIX Installation and Configuration Guide

Preparing the Host System 3–5
DECsafe Available Server Environment
(ASE)
HSG60 disk devices can be used with the DECsafe Available Server Environment (ASE)
for Tru64 UNIX provided a valid Host configuration (including Host adapters) is used to
support them. Refer to the Tru64 UNIX ASE Installation and User’s Guide, Software
Product Description, SPD: 44.17.xx, for further information. Refer to the Release Notes
for supported host adapters and Tru64 UNIX version levels for ASE.
Using genvmunix
NOTE: This section on genvmunix does not apply to Tru64 UNIX V5.1x, since the configuration
file has a different format for devices
If you use genvmunix to initialize the system and doconfig to build a new configuration
file, the new configuration file will only list the HSG60 LUN 0 units; nonzero LUNs will
not appear in the new configuration file.
Before rebuilding a configuration file using genvmunix, save any existing customized
configuration file that has entries for HSG60 units. After rebuilding the configuration file,
add the entries from the saved configuration file to the new configuration file.
HSG60 Units and Tru64 UNIX Utilities
This section contains notes on the interactions of some Tru64 UNIX utilities with storage
units in your MA6000 storage system.

the correct disk label.
The following example uses the HSG60 unit D101 on SCSI Bus-2. Run the file command
and specify the character mode device special file using one of the syntaxes shown below:
