4. If applicable (AIX, NetWare, 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 all cabling to the switch, EVA, and host.
• 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 StorageWorks Enterprise Virtual Array compatibility reference.
• Ensure that the correct host is selected as the operating system for the virtual disk in HP Command
View EVA.
• 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 EVA4400 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 EVA4400 devices:
1. Enter # ioscan -fnCdisk to start the rescan.
All new virtual disks become visible to the host.
2. Assign device special files to the new virtual disks with insf.
# 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
# ioscan -fnCdisk
