Verifying Storage Configuration from Host
This section briefly describes how to verify that multiple paths exist to virtual disk
units under OpenVMS.
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 ID 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 display:
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.
