Firmware for Voltaire 500 EX-D (PSID: MT_04A0110001)?

I can’t figure out what firmware to use for MT_04A0110001 (Voltaire 500 EX-D dual port). The information of the device is listed as:

Image type: FS2

FW Version: 2.7.700

Device ID: 25408

Description: Node Port1 Port2 Sys image

GUIDs: 0008f104039a1ea5 0008f104039a1ea6 0008f104039a1ea7 0008f104039a1ea8

MACs: 000000000000 000000000001

VSD: VLT-HRM

PSID: MT_04A0110001

The reason why I’m trying to upgrade the firmware is to check if that will fix the following error that appears when opensm (from MLNX_VPI_WinOF-4_80_All_win2012R2_x64.exe) is started on windows server 2012 r2 :

“Mellanox ConnectX IPoIB Adapter device reports a “Modify QP error” on qpn #0x20b8 Status #0xffffffea. Therefore, the HCA Nic will be reset. (The issue is reported in Function CMcast::CompleteJoinMcastWi).” (This message is flooding the windows server event log several times a second…)

Also, %windir%\temp\osm.log is flooded with thousands of lines repeating the same thing:

log_notice: Reporting Generic Notice type:3 num:66 (New mcast group created) from LID:1 GID:ff12:401b:ffff::ffff:ffff

log_notice: Reporting Generic Notice type:3 num:67 (Mcast group deleted) from LID:1 GID:ff12:401b:ffff::ffff:ffff

log_notice: Reporting Generic Notice type:3 num:66 (New mcast group created) from LID:1 GID:ff12:401b:ffff::ffff:ffff

log_notice: Reporting Generic Notice type:3 num:67 (Mcast group deleted) from LID:1 GID:ff12:401b:ffff::ffff:ffff

Could this may be an issue related to OpenSM only?

Thanks in advance!

Answering myself:

Firmware for Volataire 500 EX-D can be found here: Firmware for ConnectX® - Mellanox Technologies http://www.mellanox.com/page/firmware_table_ConnectXIB . Look for MHEH28-XTC (PSID: MT_04A0110001)

The problem with “Modify QP error” and osm.log flooding persists even after upgrading to firmware 2.9.100 and seems related to OpenSM when using dual port end-to-end connections with two cables.
