Applies to
- ONTAP 9
- FCP
- Brocade Switches
Issue
- Check Active IQ if this impacts your systems
- One or more hosts are unable to access one or more FCP LIFs on the storage system and are unable to login to the target LIFs.
- The problem occurs following a controller reboot or upgrades, power outage or may occur after some change in the fabric.
- Lun not getting mapped and initiators not logged into the storage post power outage.
- The storage system may log Fiber Channel fabric management server request failures with a reason
code 0x5
Example:
Wed Jun 06 17:26:09 CEST [xx4-xx-c: fct_tpd_work_thread_0: scsitarget.hwpfct.mserr:debug]: The Fibre Channel fabric management server request (RFT_ID) sent from adapter 1b failed with reason code 0x5 (Server busy/cannot perform operation), explanation code 0x0 (No additional data), and response code 0x8001.
- The switch shows that the LIF is logged into the fabric, but does not show FC4 enabled on the LIF.

- In the example above, the LIF and port have logged into the fabric, but FC4 is not enabled. The entry for the LIF should show
FC4s:FCP
.
