If devices are listed, verify FC HBA mapping mode or AL_PA addresses on the interface card.

Verify configuration

A number of configuration changes may result in an invalid configuration. If you are in doubt about the configuration, restore the interface card to the factory default configuration and proceed to configure the unit a step at a time, verifying the functionality of the configuration as changes are made.

Verify mapping

Verify that all desired devices have been discovered and mapped. If using Indexed or SCC mapping, try swapping to Auto-assigned to see if this solves the problem.

NOTE: HP recommends that you DO NOT use Auto-Assigned long-term as it exposes the library and drives to the entire SAN. Instead, a custom map should be created with only the hosts that need to communicate with the library and the drives assigned to it.

Verify devices

It may be useful to connect the SCSI target devices you are attempting to use to the native SCSI interface to verify that the devices are functional. SCSI target devices can be connected to a host SCSI bus to verify they are functional.

Verify host configuration

In some cases, it may be that the FC host bus adapter or host device driver may not be working properly. Check the configuration of these elements. It may be useful to check the release notes for the driver provided to see if there are any specific issues or required configuration. It may also be useful to ensure that you are using a current version of the host bus adapter driver and firmware.

PRLI data

The interface card supports the discovery mechanism. The interface card returns the PRLI response data as specified in Table 8.
