HSG80 ACS Solution Software V8.6 for Compaq OpenVMS Installation and Configuration Guide

Chapter 6
Verifying Storage Configuration from the Host
This chapter briefly describes how to verify that multiple paths exist to virtual disk units.
After configuring units (virtual disks) through either the CLI or SWCC reboot the host to
enable access to the new storage and enter the following command to rescan the bus:
$ MC SYSMAN 10 AUTO
. After the host restarts, verify that the disk is correctly presented to the host. The
command to use consists of the following syntax:
$ SHOW DEVICE/FULL <NAME OF VIRTUAL DISK>
For example, disk $1$DGA1 was configured with two paths, one path through host bus
adapter PGA0 and one through host bus adapter PGB0.
Use the following command to verify the configuration:
$ SHOW DEVICE/FULL $1$DGA1
The disk information returned is shown in the following table:
Disk $1$DGA1: (NOCORD), device type DEC HSG80, is online, file-oriented
device, shareable, device has multiple I/O paths, served to cluster via
MSCP Server, error logging is enabled.
