APAR status

  • Closed as program error.

Error description

  • The SAN discovery function queries device information by using a
    function of the HBA_SendScsiInquiry application programming
    interface (API). The API function does not work when a dual-port
    Fibre Channel adapter is perceived by the server as being a
    single adapter with two ports. In this case, the server can fail
    to get tape device information from the dual-port Fibre Channel
    adapter.
    The output of query SAN may have:
    ANR2034E QUERY SAN: No match found using this criteria.
    ANS8001I Return code 11.
    

Local fix

  • To resolve the issue, take one of the following actions:
    Connect the tape devices to the first port of the dual-port
    Fibre Channel adapter.
    Connect the tape devices to the second port of the dual-port
    Fibre Channel adapter and ensure that the first port is unused.
    Affected Platforms: Linux and Solaris
    Affected Release: 6.3.x, 7.1.x and 8.1.x
