and configure the unit one step at a time, verifying the functionality of the 

configuration after each change is made.

Restoring factory defaults overwrites user configurations. 

In the Serial/Telnet interface, use the save configuration 

option before resetting factory defaults to allow recovery 

of user configuration.

If the Interface Controller is working in Fibre Channel-to-SCSI Initiator 

mode and is using Indexed or SCC mapping, try changing to Auto-

assigned mapping.

Connecting the SCSI target devices directly to a SCSI interface (for 

example, a host SCSI bus) to verify that the devices are functional is 

recommended.

In some cases, the Fibre Channel HBA 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 device driver to see if 

there are any specific issues or a required configuration. It may also be 

useful to ensure that the current version of the HBA driver is being used.
Older applications can have expectations about what constitutes a valid 

SCSI ID, and thus may not correctly handle certain mappings. This is not 

an issue for the operating system or most applications. However, some 
applications may exhibit difficulties addressing target IDs greater than 15 

(16 and higher.) To resolve this situation, configure the Interface 

Controller to use hard addressing and set the AL_PA to a value that the 

HBA will be able to map with an ID less than 16.

Review the HBA device driver Readme.txt file for configuration specifics. 

An HBA may require a different configuration. HBAs typically come 

with utility programs to view or change their configurations.
