High availability commands
High availability (HA) management commands. These commands are only available with an Integration Appliance HA pair.
- The ha active command
The ha active command orders the idle machine to become active. You can only issue this command if there is no peer, or the peer machine is idle. - The ha conncheck command
The ha conncheck command provides information to help diagnose possible connection problems related to a high availability pair. This command is only available in active mode. - The ha disconnect command
The ha disconnect command Temporarily disconnects an HA pair without causing the standby machine to takeover the active machine.. This command is only available in active mode. - The ha power off standby command
The ha power off standby command powers off the Standby Integration Appliance in a high availability pair. This command is only available in active mode. - The ha power on standby command
The ha power on standby command powers on the Standby Integration Appliance in a high availability pair. This command is only available in active mode. - The ha reboot command
The ha reboot command completes a system reboot of the Integration Appliance you specify: active or standby. The ha reboot command is only available for use in an HA pair. When you issue the ha reboot standby command, the Standby Integration Appliance reboots, while the Active Integration Appliance continues to process data. When you issue the ha reboot active command, the Active Integration Appliance shuts down all routing services and then reboots. The Standby Integration Appliance does not provide failover capabilities and data is not processed until the Active Integration Appliance is back online. To simulate failover capabilities, switch the modes of the machines in the HA pair using theha switch command – the Active Integration Appliance (A1) becomes the Standby Integration Appliance (S2) and Standby Integration Appliance (S1) becomes the Active Integration Appliance (A2). After the Integration Appliances in the HA pair have switched modes, issue the ha reboot standby command. S1 continues to process data, while A1 is rebooting. - The ha show lastaccess command
The ha show lastaccess command displays the last 10 state transitions on the Integration Appliance. Only available in idle mode. - The ha show pairstatus command
The ha show pairstatus command displays status of the high availability pair, providing information about which Integration Appliance is Active and which is Standby. Only available in active mode. - The ha switch command
The ha switch command switches the roles of the Integration Appliance in a high availability pair. The Active machine becomes the Standby machine and the standby machine becomes Active. Only available in active mode.
