5.5.1.1 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
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
-I- Discovering the fabric - Running: ibdiagnet -skip all
-I- Added 10 in-band devices
2. List the discovered mst inband devices run "mst status".
[root@mymach]> mst status
MST modules:
------------
MST PCI module loaded
MST PCI configuration module loaded
...
Inband devices:
-------------------
/dev/mst/CA_MT25418_sw005_HCA-1_lid-0x0001
/dev/mst/SW_MT47396_lid-0x0011
/dev/mst/SW_MT48438_lid-0x0003
Identify the switch you want to update according to its description or its LID.
in the examples below we will use
Query the switch to determine the current FW version:
[root@mymach]> flint -d /dev/mst/SW_MT48438_lid-0x0003 q
