  • 1.  PBHA initial sync complete but recovery point outside policy

    Hi everyone, hoping if anyone knows what is going on with this PBHA i/p mirror.

    Not entirely sure what the below means?

    We have initially replicated the full 4.13Tb but yesterday found a replication of around 386Gb running……and this completed.

    Today I find a replication of 230Gb running but with 'Recovery point outside policy' warning? 

    At current rates the 230Gb replication should finish later this afternoon…….but not sure if this now means there will be subsequent replications for each of the interim days?

    The links are 100MB with compression enabled and copy rate of 100%.

    No change volumes set so wondering if this is what's happening and they are required.

    Thanks Stuart.

    Hi Stuart Wade.

    What do you mean by 'the links are 100 MB'?
    It seems you are not using FC. I'm not sure if using 100 MB is supported by IBM.

    Hi, The minimum bandwidth requirement for the inter-site link is 10Mbps so we are well within the requirements for i/p replication

    Do you have any data on the write rate to the volumes?  From past non-PBHA based replication over IP, GM with CV, it's very easy for the host to write more data than the IP based replication can keep up with and it ends up lagging, sometimes by days!

    Hi Phill, yep this is the case here, Just wanted to confirm with IBM and Chris Bulmer has replied. PBHA is cycling into snaps because its getting behind. Its clever the way it automatically does this now on the newer code.

    Ive mailed the customer to say the pipe is too small and it will never catch up unless they make it larger!
