Mst ib add errs with "name 'mtcr' is not defined"

Infrastructure & Networking Switches and Gateways InfiniBand/VPI Switch Systems

Hello,

in a fabric with several unmanaged QM87xx, from a a host with ConnectX6 HCA, I’ve tried to get in-band access to the switches (which worked two years ago) in order to remove split-port mode for a port I’ve set it on 2 years ago.

However, currently, the `mst ib add`command keeps failing like

# mst ib add
-I- Discovering the fabric - Running: ibdiagnet
-E- name ‘mtcr’ is not defined
-I- Added 0 in-band devices

The same error happens in other environments (different fabrics) where it also used to work years ago but with about the same current FW/SW levels:

RHEL8

The string ‘mtcr’ is not contained in the output of the `ibdiagnet`command:

# ibdiagnet | grep mtcr | wc -l
0

How can I get rid of the error?

Thx
