HP EVA3000 - Controller Cache battery

Hi,
I am using HP EVA 3000 in my environment

We are getting an amber light for the cache batteries of controller A , for which we are going to replace the same.

My query is

1) Whether the operations (read/write) will be caried out by controller A or controller B till the battery gets replaced

2) if the opeartions are taken by controller B,will the performance gets affected.

Tnaks in advance

regards,
dhiyan

For EVA3k this may be different and depending on firmware version (a/a vs. a/p), but on later arrays all operations will be done by the other controller.

Hope this helps!
Regards
Torsten.

In command view go to virtual disks -> (select one) -> presentation and read the Managing controller: value.

Hope this helps!
