1. From HP P6000 Command View, create a virtual disk on the EVA6400/8400. 2. Specify values for the following parameters: • Virtual disk name • Vraid level • Size 3. Present the virtual disk to the host you added. 4. If applicable (OpenVMS), select a LUN number if you chose a specific LUN on the Virtual Disk Properties window. Verifying virtual disk access from the host To verify that the host can access the newly presented virtual disks, restart the host or scan the bus. If you are unable to access the virtual disk: • Verify that all cabling to the switch, EVA, and host is properly connected. • Verify all firmware levels. For more information, see the Enterprise Virtual Array QuickSpecs and associated release notes. • Ensure that you are running a supported version of the host operating system. For more information, see the HP P6000 Enterprise Virtual Array Compatibility Reference. • Ensure that the correct host is selected as the operating system for the virtual disk in HP P6000 Command View. • Ensure that the host WWN number is set correctly (to the host you selected). • Verify the FCA switch settings. • Verify that the virtual disk is presented to the host. • Verify zoning. Configuring virtual disks from the host After you create the virtual disks on the EVA6400/8400 and rescan or restart the host, follow the host-specific conventions for configuring these new disk resources. For instructions, see the documentation included with your server. HP-UX Scanning the bus To scan the FCA bus and display information about the EVA6400/8400 devices: 1.

1.
From HP P6000 Command View, create a virtual disk on the EVA6400/8400.
2.
Specify values for the following parameters:
•
Virtual disk name
•
Vraid level
•
Size
3.
Present the virtual disk to the host you added.
4.
If applicable (OpenVMS), select a LUN number if you chose a specific LUN on the Virtual
Disk Properties window.
Verifying virtual disk access from the host
To verify that the host can access the newly presented virtual disks, restart the host or scan the bus.
If you are unable to access the virtual disk:
•
Verify that all cabling to the switch, EVA, and host is properly connected.
•
Verify all firmware levels. For more information, see the Enterprise Virtual Array QuickSpecs
and associated release notes.
•
Ensure that you are running a supported version of the host operating system. For more
information, see the
HP P6000 Enterprise Virtual Array Compatibility Reference
.
•
Ensure that the correct host is selected as the operating system for the virtual disk in HP P6000
Command View.
•
Ensure that the host WWN number is set correctly (to the host you selected).
•
Verify the FCA switch settings.
•
Verify that the virtual disk is presented to the host.
•
Verify zoning.
Configuring virtual disks from the host
After you create the virtual disks on the EVA6400/8400 and rescan or restart the host, follow the
host-specific conventions for configuring these new disk resources. For instructions, see the
documentation included with your server.
HP-UX
Scanning the bus
To scan the FCA bus and display information about the EVA6400/8400 devices:
1.
Enter the
# ioscan
-fnCdisk
command to start the rescan.
All new virtual disks become visible to the host.
2.
Assign device special files to the new virtual disks using the
insf
command.
# insf -e
NOTE:
Uppercase
E
reassigns device special files to all devices. Lowercase
e
assigns device
special files only to the new devices—in this case, the virtual disks.
The following is a sample output from an
ioscan
command:
# ioscan -fnCdisk
