To update an MT47396 InfiniScale® III and MT48436 InfiniScale® IV switch devices 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.

2. Make sure the local ports are active by running ‘ibv_devinfo’.

3. Obtain the device LID. There are two ways to do that:

a. Using the “mst ib add” command:

The “mst ib add”runs the ibdiagnet/ibnetdiscover tool to discover the InfiniBand fabric and

then lists the discovered IB nodes as an mst device. These devices can be used for access by

other MFT tools.

To list the discovered mst inband devices run “mst status”.

For Linux device names should be listed with the /dev/mst prefix. For Windows, no pre-

fix is required.

[root@mymach]> /etc/init.d/opensmd start

opensm start [ OK ]

[root@mymach]> mst ib add

-I- Discovering the fabric - Running: /opt/bin/ibdiagnet -skip all

-I- Added 3 in-band devices
