Procedure

  1. The I/O enclosure device adapter card is reporting a problem with one or more FC-AL cables. The problem cable may have a visual problem; unplugged, partially plugged or physically damaged or other problem such as an internal failure. The device adapter card is listed in the serviceable event FRU list. See Figure 1 and Figure 2.

    Inspect the FC-AL cables. Did you find a visible problem?

    • Yes, go to the next step.
    • No, if the failing FC-AL cables are listed in the FRU list, go to the next step to replace that cable. If no cable is listed, contact your next level of support.
