4.3.2.1 Instructions for Reprogramming Over the InfiniBand Network
To update an InfiniScale IV switch device having a specific GUID (for example,
0x00000006660abcd0) or LID, the following are the recommended steps to update the device
firmware.
1. Make sure all subnet ports are in the active state. One way to check this is to run opensm, the
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.
1. Use the “mst ib add” command:
The “mst ib add” runs the ibdiagnet/ibdiscover 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
