0x00000006660abcd0) or LID, the following are the recommended steps to update the device firm-

Subnet Manager.
[root@mymach]> /etc/init.d/opensmd start
opensm start [ OK ]
2. Make sure the local ports are active by running ‘ibv_devinfo’.
3. Obtain the device LID. There are two ways to do that:
I. Using the “mst ib add” command:
The “mst ib add” runs the ibdiagnet tool to discover the InfiniBand fabric and then lists the discovered IB
nodes as an mst device under /dev/mst/ directory. These devices can be used for access by other MFT
tools.
[root@mymach]> mst ib add
