Verifying FCA installation
After configuring the ports on the disk array, verify that the FCAs are installed properly.
Use the ioscan –f command, and verify that the rows shown in the example are displayed. If
these rows are not displayed, check the host adapter installation (hardware and driver installation)
or the host configuration.
Example
# ioscan –f

Verifying device recognition
Verify that the HP-UX system recognizes the new devices on the disk array.
If the SCSI paths were defined after the system is powered on, you must halt and restart the system
to allow the system to recognize the new devices.
To verify device recognition:
1. Log in to the system as root.
2. Display the device data to verify that the system recognizes the newly installed devices on the
disk array. Use the ioscan –fn command to display the device data.
On a system with a large LUN configuration, HP-UX cannot build device files on all LUNs.
Enter insf –e to build all missing device files.

In the example:
• HP OPEN-9 device: SCSI bus number = 14/12, bus instance = 6, SCSI target ID = 0,
LUN = 0.
• HP OPEN-9*2 device: SCSI bus number = 14/12, bus instance = 6, SCSI target ID =
0, LUN = 1.
• If UNKNOWN is displayed for a disk, the HP 9000 system or HP Integrity system might
be configured properly. See the HP documentation or contact HP customer support for
assistance with the HP 9000 system, HP Integrity system, or the HP-UX operating system.
3. Enter the device data for each disk array device in a table. See “Path worksheet” (page 111).
4. Construct the device file name for each device, using the device information, and enter the
file names in your table. Use the following formula to construct the device file name:
