sethalink

Specify a non-default link to be used for HA replication.

Purpose

By default, high availability configurations use the 10 Gb link eth21 for replicating data between the two appliances in the HA group.

Advanced users, who are networking experts, can choose to use a different interface for replication. The sethalink command is used to configure the alternative interface. You might, for example, choose to use one of the 40 Gb or 100 Gb links for replication.

Parameters

-r replicationIP
Specifies the IP address of the interface to be used for replication. You must specify the IP address using ip v4 dotted decimal notation (for example, 192.0.2.8).
-d
Return to the default configuration.

Usage Notes

  • This command must be run from the IBM® MQ administration mode. If the system is in the IBM MQ administration mode the prompt includes mqa(mqcli)#. To enter the IBM MQ administration mode, enter mqcli on the command line. To exit the IBM MQ administration mode, enter exit on the command line.
  • The IP address specified must map to a valid local interface or aggregation interface, otherwise the command fails. (You cannot specify a VLAN interface.)
  • The local interface should be at least a 10 Gb link, otherwise your are warned that performance might be poor.
  • If an HA configuration is already active, the command is rejected and an error message issued.

Example

The following example shows the IP address 192.0.2.15 being allocated for replication in the HA configuration:

sethalink -r 192.0.2.15
