    hi,
    Could you type this command

    lsattr -El fscsi0
    Possible Result

    attach switch How this adapter is CONNECTED False
    dyntrk no Dynamic Tracking of FC Devices True
    fc_err_recov delayed_fail FC Fabric Event Error RECOVERY Policy True
    scsi_id 0x1c0d00 Adapter SCSI ID False
    sw_fc_class 3 FC Class for Fabric True

    if the parameter dyntrk = yes, you can tested with dyntrk to no (yes with SAN disk , no with Tape SAN)

    you must delete your configuration with rmtxx before this command

    chdev –l fscsi0 –a dyntrk=no –a fc_err_recov=fast_fail –P

    -P = Permanent

    Best regard
