Verifying the interface controller confi guration
Verify the following:
• The FC interfac
e controller spee d is set correctly
• Theconnectiontypeissetcorrectly
• The host is add ed 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 configu ration of
these elemen
ts.
It may be useful to check the release notes for the device driver to see if there are any specificissuesor
arequiredconfiguration. 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.
Verif ying HBA device driver information
Review the HBA device driver Readme.txt file for configuration specifics. An HBA may require a different
configuration. H BAs typically come with utilit y programs to view or change their configurations.
