HP ESL E-series Tape Libraries - Manual (Page 84)

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.
Table 15 Terminal configuration settings
Baud rate Autobaud, 9600, 19200, 38400, 57600, 115200
Data Bits 8
Stop Bit 1
Parity None
Flow Control None or XON/XOFF
If problems persist, verify the cabling.
If a valid Ethernet IP address is configured, serial configuration settings can also be set via Telnet.
