Scanning the bus
Enter the following command to scan the bus for the OpenVMS virtual disk:
$ MC SYSMAN IO AUTO/LOG
A listing of LUNs detected by the scan process is displayed. Verify that the new LUNs appear on
the list.
NOTE:
The EVA6400/8400 console LUN can be seen without any virtual disks presented. The
LUN appears as $1$GGAx (where x represents the console LUN ID on the controller).
After the system scans the fabric for devices, you can verify the devices with the SHOW DEVICE
command:
$ SHOW DEVICE NAME-OF-VIRTUAL-DISK/FULL
For example, to display device information on a virtual disk named $1$DGA50, enter $ SHOW
DEVICE $1$DGA50:/FULL
.
The following output is displayed:
Disk $1$DGA50: (BRCK18), device type HSV210, is online, file-oriented device,
shareable, device has multiple I/O paths, served to cluster via MSCP Server,
error logging is enabled.

You can also use the SHOW DEVICE DG command to display a list of all Fibre Channel disks
presented to the OpenVMS host.
NOTE:
Restarting the host system shows any newly presented virtual disks because a hardware
scan is performed as part of the startup.
If you are unable to access the virtual disk, do the following:
•
Check the switch zoning database.
•
Use HP P6000 Command View to verify the host presentations.
•
Check the SRM console firmware on AlphaServers.
•
Ensure that the correct host is selected for this virtual disk and that a unique OS Unit ID is used
in HP P6000 Command View.
