[ofa-general] opensm: Unsupported attribute = 0xFF02

[Kilian CAVALOTTI]

Hi,

I'm trying to use opensm as a standby SM on a fabric where the master SM 
is running on a Cisco SFS-7000D (TopspinOS 2.9.0 releng #147)

The switch (Master SM) logs report the following:

Oct 30 12:08:46 10.0.100.2 ib_sm.x[588]: %IB-6-INFO: Configuration caused by SM role change
Oct 30 12:08:55 10.0.100.2 ib_sm.x[605]: %IB-6-INFO: Initialize a backup session with Standby SM guid 00:05:ad:00:00:08:cf:0d
Oct 30 12:09:05 10.0.100.2 ib_sm.x[605]: %IB-6-INFO: Session initialization failed with Standby SM guid 00:05:ad:00:00:08:cf:0d
Oct 30 12:11:05 10.0.100.2 ib_sm.x[605]: %IB-6-INFO: Session not initiated: Cold Sync Limit exceeded for Standby SM guid 00:05:ad:00:00:08:cf:0d

And the opensm (Standby SM) logs show this:

I'm not sure what this ERR 3107 means, is there something I could do about
it? Is there a way to use OpenSM as a standby SM with a managed switch?

For information, I'm using OFED 1.2 (the Cisco fcs version) and details
about the HCAs are below:
