Scanning The Bus - HP 6100 User Manual

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 EVA4x00/6x00/8x00 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 Command View EVA 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 Command View EVA.
