INFINIBAND: How To Add Node/Host Port GUIDs To A Particular Partition On Infiniband (IB) Switches? ("smpartition" Command)

Follow below steps to follow on Infiniband Switch running SM Master to add Node/host port GUIDs to a particular partition.

1. Login to the IB Switch running SM master as root user. "getmaster" command can be used to identify which IB Switch is running the SM master.

2. Start the SM partition using below command.

smpartition start

3. Add the Node/Host Port GUIDs to a partition using below command.

# smpartition add -pkey <PKey> -port <Port GUID1> <Port GUID2> ... <Port GUIDN> -m <membership>

For e.g. if you want to add port GUIDs 0010e0000164e371 and 0010e0000164e372 as full members to partition key 8008, your command looks as follows:

# smpartition add -pkey 0x0008 -port 0x0010e0000164e371 0x0010e0000164e372 -m full

NOTE: We have to use 0x0008 for 8008 partition (as per new IB firmware version standards from 2.1.5 & above) and for GUIDs we have to append 0x at the beginning.

4. Now commit the partition so that the new partition key addition changes are committed using below command.

5. Now run below smpartition command and check if newly created partition is seen.
