Interface controller problems
Most problems with the interface controller occur during the initial installation. Before proceeding
with advanced troubleshooting techniques, make sure that all connections are correct and review the
configuration and firmware. If a new interface controller was installed, the library may need to be
rebooted for the controller configuration to be set.
LED indicators
The LED indicators on the interface controllers (see
“ HP StorageWorks e2400-FC 2Gb interface controller ” on page 57 and
“ HP StorageWorks e2400-FC 4Gb interface controller ” on page 58) are useful for diagnosing
various problems:
• FC port LEDs—Indicate FC activity (ACT) and link (LNK) status. If the link LED is not lit, it can
indicate a problem with an FC link. Make sure that the FC port configuration and cabling
is correct.
• Ethernet LEDs—Indicate activity and link status. If one of these indicators is not lit or stays
continuously lit, it can indicate a problem with the network connection or cabling. Make sure
that the network connection is correct. The port must be connected to a 10/100Base-T Ethernet
network to function properly.
Basic troubleshooting
Simplify the installation by reducing it to the most basic configuration. Then, add elements one at a time,
making sure that the library operates correctly after each step.
Basic troubleshooting includes making sure that the setup and connections are correct:
• The FC port connection
• The interface controller configuration
• Devices
• Host configuration
• HBA device driver information
• Serial port configuration
