|Steps to accomplish the task of migrating IPoIB from default to custom partition|
|Step 1: Identify an unused InfiniBand Partition key|
|Step 2: Determine if any node need to be added as limited member to the IB partition|
|Step 3: Collect all IB port GUIDs of the host compute nodes that need to be part of this new IB partition|
|Step 4: Identify the IB switch running Master Subnet Manager|
|Step 5: Start IB partition editing on Master SM Switch|
|Step 6: Create IB partion on Master SM Switch|
|Step 7: Add all IB port GUIDs in the new IB partition|
|Step 8: Save and commit the switch configuration|
|Step 9: Verify that the IB partition information is propagated into all Standby SM Switches|
|Step 10: Backup current IPoIB configuration on all host compute nodes|
|Step 11: Migrate current IPoIB configuration into new IB partition based configuration|
|Step 12: Reboot first two host compute nodes one at a time|
|Step 13: Verify the connectivity between the rebooted nodes|
|Step 14: Reboot remaining host compute nodes one at a time|
