Replace a Gateway
This procedure briefly outlines the steps to replace a gateway within an
InfiniBand fabric. Refer to Gateway
Service, Gateway
Administration, and Gateway
Installation 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 gateway to be removed to the lowest.
Wait for any handover to complete.
-
Create a backup of the gateway configuration for the gateway to be
removed.
-
Completely power off the gateway.
-
Remove the gateway from the fabric and management network.
-
Install and power on the replacement gateway, but do not connect it to the
fabric or the fabric's management network.
-
Configure the replacement gateway with the same host name, IP address, as
the gateway removed.
-
Restore the gateway configuration previously backed up.
-
Readout and store the SM priority from the restored gateway configuration
using setsmpriority list and then set the SM priority to
the lowest in the Infiniband Subnet.
-
Completely power off the replacement gateway.
-
Connect the replacement gateway to the fabric's management network and the
fabric.
-
Power on the replacement gateway.
Wait for any negotiation and propagation to complete.
-
Setup the smnodes list and fabric configuration file
for the replacement gateway, and ensure that the list and file are
consistent with other gateway and switch lists and files.
-
Perform a smpartition start and smpartition
commit from the master Subnet Manager.
Wait for the partition configuration to propagate to the replacement
gateway.
-
Perform a smsubnetprotection start and
smsubnetprotection commit from the master Subnet
Manager.
Wait for the secret M_Key policy to propagate to the replacement
gateway.
-
Set the priority of the replacement gateway to that originally of the
removed gateway.
Wait for any handover to complete.
