To update an MT48436 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
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
-I- Running ibdiagnet to discover the fabric ...
Loading IBDIAGNET from: /usr/local/lib/ibdiagnet1.2
-W- Topology file is not specified.
Reports regarding cluster links will use direct routes.
Loading IBDM from: /usr/local/lib/ibdm1.2
-I- Using port 1 as the local port.
-I- Discovering ... 3 nodes (2 Switches & 1 CA-s) discovered.
