0.F.en.05 CRITICAL condition—Invalid fibre channel character
This symptom can occur under the following conditions:
• The incoming data stream is corrupted.
• A cable is not completely connected.
• The signal is degraded.
This error prevents the controller from transferring data on a loop and eliminates the enclosure
dual-loop capability. This error remains active until the problem is fixed.
To correct this problem, record all six characters of the condition report, then contact your HP
authorized service representative.
CAN bus communication port conditions
The format of a CAN bus communication port report is 1.1.03.ec , where:
• 1.1. is the communication port element type
• 03. is the two-character CAN bus element number
• ec is the error code
NOTE: The only communication port for which conditions are reported is the CAN bus. Therefore,
the element number is always 03.
Resetting the EMU
In some cases, the only corrective action for an EMU error is to replace the EMU. Call your
authorized service representative if this action is required. Another option is to reset the EMU using
the following procedure:
1. Firmly grasp the EMU mounting handle and pull the EMU partially out of the enclosure.
NOTE: You do not need to remove the EMU from the enclosure or disconnect the cables.
You must avoid putting any strain on the cables or connectors.
2. Wait 30 seconds, and then push the EMU in and fully seat the element in the backplane. The
EMU should display any enclosure condition report within two minutes.
1.1.03.01 NONCRITICAL condition—Communication error
This condition report indicates that the EMU is unable to communicate over the CAN bus. Continued
operation under these conditions may result in the failure to restore loop functionality when there
is a disk drive disrupting the loop. This error initiates an automatic recovery process. This condition
report remains active until the automatic recovery process is complete or until the EMU is reset.
Complete the following procedure to correct this problem:
1. Record all six characters of the condition report.
2. Reset the EMU.
3. Observe the EMU to ensure the error does not recur within the first minute.
4. If the error does recur, contact your HP authorized service representative. The EMU is
inoperative and must be replaced as soon as possible.
1.1.03.02 INFORMATION condition—Recovery completed
This condition report notes completion of the automatic recovery initiated by the occurrence of the
1.1.03.01 condition. This condition report remains active until one of the following occurs:
• 90 seconds elapses
• The CURRENT ALARM QUEUE is read via SES
• The RECENT ALARM LOG is read via SES
No action is required.
