Workspace PowerHA for AIX

Add SmartDR control functions to SRDF file sets for PowerHA

Currently we have customer applications which have servers with PowerHA installed using SVC SAN storage. I am managing the migration from SVC SAN storage to EMC PMAX SAN Storage which includes a new feature called SmartDR (AKA MetroDR) fromDell-EMC.

Currently when our team simulates a DR failover we use PowerHA to control all the SVC SAN storage commands. With the deployment of PMAX SAN Storage with SmartDR we are being told by the Dell-EMC labs that PowerHA requires a newset of "symmdr" libraries that can be used to control EMC SAN Storage commands. Without this library our team needs to execute manual process tasks when we execute a DR failover.

    .This functionality is delivered with PowerHA 7.2.5 SP1 Generally available for download from June 2021.
    Some links to KC about the functionality

    *** Developer: Please include this information with the request:

    Hi Joe,
    As per our call this morning reporting on the SmartDR POC, and testing we have been performing. We have found that with a SmartDR configuration you cannot perform a SWAP personality where as you can reverse the direction of replication from Gough to Barrie or visa versa. This is a feature only available with the traditional SRDF/A replication using powerHA with Consistency Groups or Manual SWAP.

    Now that we are moving to SmartDR, we need to introduce an extra manual step to perform a simulate SWAP which will be part of the WLS process as an intrim measure by using a CRON Job that will perform an Update from DR->PROD at a set time interval that configurable.

    We need to include insure that when the IBM Developers work on m importing the SmartDR failover/failback feature that we have the option to perform request Updates to R1 from DR site.

    Please provide the following to be included into the development:

    PowerHA - SmartDR - Symmdr commands
    1. Ability to Failover from Prod -> DR
    2. Ability to enable UPADATE DR->PROD (R1)
    3. Ability to Fail-back and copy full remaining Deltas from DR -> PROD

    I can provide more details when we get closer to that stage. Raymond Faraone.
