Configuring FC switches

OpenVMS supports Fibre Channel only in a switched fabric topology. Refer to the switch documentation
to set up the switch.

Connecting the disk array

The HP service representative connects the disk array to the host by:
1. Verifying operational status of the disk array channel adapters, LDEVs, and paths.
2. Connecting the Fibre Channel cables between the disk array and the fabric switch or host.
3. Creating Fibre Channel zones connecting the host systems to the array ports. Refer to your switch
manufacturer's documentation for information on setting up zones.
4. Verifying the ready status of the disk array and peripherals.

Verifying disk array device recognition

Verify that the host recognizes the disk array devices:
1. Enter the show device dg command:
$ show device dg
2. Check the list of peripherals on the host to verify the host recognizes all disk array devices. If
any devices are missing:
If host mode option 33 is enabled, check the UUID values in the XP Remote Web Console
LUN mapping
If host mode option 33 is not enabled, check the CU:LDEV mapping
To ensure the created OpenVMS device number is correct, check the values do not conflict
with other device numbers or LUNs already created on the SAN
LUN/CU:LDEV and FCA WWN mappings on the host port
Run the $ mcr sys$etc:fibre_scan command and capture the output to scan for the
devices that OpenVMS discovers during a scan of the Fibre Channel storage devices.
3. Record the disk numbers and other device information. You will need the disk numbers when you
format, partition, and mount the disks.

Configuring disk array devices

Configure the disk array devices in the same way you would configure any new disk on the host
server. Creating scripts to configure all devices at once may save you considerable time.

Initializing and labeling the devices

Use the initialize command to format each disk array volume and write an identifying label on
it:
