    Hello,

    Answer is yes and No....

    Yes, they can be removed with ease.
    No, in that the complete process is not straight forward, especially if you are doing it without an outage.

    The Cache battery is in each controller module, so the modules need to be put offline and online while performing the tasks.
    You will also need to reset the Battery Counter after you have finished.

    Also, make sure when you are finished that you schedule the Battery re-learn cycle outside of production time.
    You will also want to make sure that Write Cache is enabled again on all volumes (once battery is healthy/charged),
    sometime you can see funny things happen and it will remain disabled.

    Bernie.

    Apologies, I was taking about the DS3500.

    With the DS4700 the cache battery is separate to the controller and is "Hot swap-able".
    Make sure you prepair them for removal and confirm the Service Action Allowed LED (OK to Remove) is ON.

    My other comments still apply.

      Hello,

      Thanks for your response but I don't ask how to change this BBU but if this considered as a consumable parts or not ?
