Replace a Switch
This procedure briefly outlines the steps to replace a switch within an
InfiniBand fabric. Refer to the following books for more information:
This procedure assumes that a secret M_Key policy is in use and the fabric is
partitioned.
-
Set the priority of the switch to be removed to the lowest.
Wait for any handover to complete.
-
Create a backup of the switch configuration for the switch to be
removed.
-
Completely power off the switch.
-
Remove the switch from the fabric and management network.
-
Install and power on the replacement switch, but do not connect it to the
fabric or the fabric's management network.
-
Configure the replacement switch with the same hostname, IP address, and
lowest priority as the switch removed.
-
Restore the switch configuration previously backed up.
-
Completely power off the replacement switch.
-
Connect the replacement switch to the fabric's management network and the
fabric.
-
Power on the replacement switch.
Wait for any negotiation and propagation to complete.
-
Perform a smpartition start and smpartition commit from the master Subnet
Manager.
Wait for the partition configuration to propagate to the replacement
switch.
-
Perform a smsubnetprotection start and smsubnetprotection commit from the
master Subnet Manager.
Wait for the secret M_Key policy to propagate to the replacement
switch.
-
Set up the smnodes file and fabric configuration file for the replacement
switch, and ensure that the list and file are consistent with other switch
and gateway lists and files.
- (Optional)
Set the priority of the replacement switch to that originally of the
removed switch.
Wait for any handover to complete.
