How to change disk enclosure id on EVA 6400

[TinKy]

Hi

I have already set up an EVA 6400 with 8 box, each disk enclosure has already take one unique number, It´s possible change this values ??

It's possible, but really not recommended - you should not change it .

Has anyone actually changed the disk enclosure IDs successfully on a P6000 disk array with XCS11....?

In a 2C18D array, if it was requested to change the disk enclosure IDs, from top to bottom, linerly say IDs from 0 to 17.  Can it be done by powering up the controllers 1st then one disk enclosure at a time?  Please share your stories.

Yes, I did this during a fresh installation, but this is not recommended for whatever reason (sidSet command on the enclosure).

As an HP Channel Partner, my customer will ask why is it not recommended.

Does the controller XCS FW, via I/O modules, set the enclosure IDs for optimal enclosure access?  Will manual enclosure ID settings affect the disk enclosure access?

As far as I remember when you switch on the eva the first time, the controller will set the disk enclosure id's by first-come-first-serve and that's it. A change is just not recommended whitout telling a reason.
