Note the following for the example Assure MIMIX for AIX configuration:
-
Performed using PowerHA for AIX 6.1.0.7
-
Names used such as, Cluster Nodes, resource groups are arbitrary. The integrator can choose to use any names.
-
Topology configuration for networks, communication interfaces and devices is not shown in this example because it is environment specific.
-
Notification scripts are not provided and are the responsibility of the integrator.
-
The implementation of the user application in this example is a suggestion and could be done differently at the integrator’s preference.
-
Has a Primary Context ID of 85 and Failover Context ID of 850.
The following Assure MIMIX for AIX scripts are provided for the PowerHA for AIX configuration. These scripts require parameters -C <Primary Context ID> and for the first two scripts optionally -P if called from the Production_Server resource group. These scripts will log to "/usr/scrt/log" if the "HACMP Log File Parameters" have "Debug Level" set to "high".

required to reset the LFCs on Failover. This depends on the number
of LFCs on the Recovery Server and the system performance. With
20,000 LFCs it could typically take up to 15 minutes.
