Power Enterprise Pools – Real-world Lesson Learned!

  • 1.  Power Enterprise Pools – Real-world Lesson Learned!

    Posted yesterday

    Last year, we faced a major MDC and DR disaster - everything went down on MDC, and we didn't know how to handle it properly.
    At that time, we had no idea how to use the PEP force remove options.

    We've learned it the hard way, and I wanted to share this with our community - it might save someone valuable time during a crisis!

    πŸ‘‰ During the incident, HMC connectivity between PROD and DR was unavailable, and purchasing COD wasn't an option.
    However, the command-line force options turned out to be a lifesaver:

    Note: pool grace period was set 2 by default once everything back PEP in-compliance to compliance status changed

    # chcodpool -o remove -m <PROD> -p <PoolName> -r proc -q <Quantity> --force
    # chcodpool -o remove -m <PROD> -p <PoolName> -r mem -q <Quantity> --force
