Verifying the Host Configuration

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.

There are cases where 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 router 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.

Verifying HBA Device Driver Information

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.

Verifying Serial Port Configuration

If you are having problems connecting via the serial interface, verify the
configuration of the terminal or terminal emulation program.

If problems persist, verify the cabling.

If a valid Ethernet IP address is configured, serial configuration settings can also
be set via Telnet.
