Changing ID of controller on EVA 4000

Changing ID of controller on EVA 4000

Good day everyone,
I need to change the ID of a EVA4000 Controller (actually ID is 4) to ID 3 and the enclosure with ID 4 to ID 3.

Why I need to do that is because we have a customer that has his EVA4000 alarmed on port DP1B (DG is alarmed too) and checking the .xml file in Navigator tools it show the warning messages: "3 disk enclosure(s) found. Controllers should be located @ shelf 4 for HSV200 configuration."

My environment is as follows:
Controller B & Controller A (ID 3)
Disk Enclosure 4
Disk Enclosure 2
Disk Enclosure 1

My question is: making that change, what could be happened with the EVA Metadata? Or, just making this ID change (between Enclosure 4 and Controller 3) there will not be any impact in the EVA?

Thanks for any answers anyone may be able to give me

Hi Pablo,

Changing the ID of the controller and the disk enclosure will have no effect on the data on the EVA.

I very much doubt though, that these warnings have anything to do with the alarms that your customer has seen.

How's that you have Navigator? That's an HP rectricted tool. You should concentrate on finding what's causing trouble on DP-1B.
Check for "missing data", "SCSI parity error" and ASC/ASCQ events, make a table...
You should know what to do if you have Navigator.

vcespon: Actually access to Navigator has been granted to some personell outside HP.

I do not see any need to change the ID. A EVA 2C2D config is delivered with the controllers at id3 so it is common that a EVA 2C2D expanded with a new diskshelf (2C3D) has the IDs numbered as you describe. This is not a "non-supported" config.

However the controller should never hav id 7 but this is not an issue wiht EVA 4000.

You should carefully look at loop B to isolate the problem.
