Cisco UCS FI ports fail to show in devicelogin --show output
Applies to
- Brocade Switches
- FOS 8.2.1
- MAPS
- Cisco UCS FI
Issue
- Starting from FOS 8.2.1, there is a MAPS feature which allows the switch to keep track of Cisco UCS FI ports and the number of NPIV devices logged in on each port.
- Additionally, this feature also allowed dynamic redistribution of NPIV logs across Cisco UCS FI uplinks. For more information on how re-balance feature works, watch this YouTube video from Brocade - Brocade FOS Automatically Rebalance UCS NPIV logins
- With this issue, FOS fails to recognize Cisco UCS FI ports, which limits the functionality of NPIV re-balance feature by running command
devicelogin --rebalance
Example:
In this scenario, the number of initiators/NPIV is split across 4 ports, but only 2 ports are getting listed in the devicelogin --show
- In the
switchshowoutput, NPIV devices listed as expected.
