2. Double-click the FC HBA.
The SCSI devices should be listed. If no devices are listed, verify the FC interface controller
configuration, FC HBA configuration, and cabling. If devices are listed, verify the FC HBA mapping
mode or the AL_PA addresses.
Verifying the interface controller configuration
Verify the following:
• The FC interface controller speed is set correctly
• The connection type is set correctly
• The host is added to Secure Manager and given permission to communicate with the library.
Verifying devices
HP recommends using Command View TL to verify that the devices are functional.
Verifying the host configuration
In some cases, the FC 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 in a direct attach configuration, configure the FC 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.
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.
