Reset EVA controller NVRAM

[Aissa]

Hi all,

is there a way to reset the HSV controller NVRAM, or to reset it to factory default. I can't use CMD view EVA 6.0.2 any more !!

Thx

What's the exact problem you have?

Have you updated the firmware on the EVA?

Current Command View version is 9.2 and it works with all currently supported firmwares.

Hi,

I tried CMDV 9.1 before buying it, and now i need to go back to manage my EVA like before. The probleme is with my 6.0.2 i can't see my controller.

[Víctor Cespón]

This is a known issue. If you use Command View 9.x you cannot go back to CV 6.x. You'll not see the controllers on Command View.

Basically CV 6.x is currently not supported and you cannot downgrade to it.

You should get a license and use CV 9.2.1.

In order to go back you need to "destroy" the current setup including data - called "uninitialize".

[Aissa]

how can you say that, talking about destroying data !

This is not a solution or a very bad joke or an idea.

Thank you anyway

As far as I know - it won't even work. The problem is that the contents of the controller module's NVRAM have been changed, as you wrote already wrote. An UNINITIALIZE will not reverse that.

[Torsten.]

As said, this is the better advise:

You should get a license and use CV 9.2.1.

[Aissa]

We plan and it is mandatory to go 9.2 i know that but we can't do that for now.

So i have 2 choices :

- get new controllers
- find a way to "clear NVARM"

[Torsten.]

IMHO both choices will not help.

[Aissa]

The first one work, i try it with
controllers and CMD View 8 and i can see my controller when i go back to 6.0.2

[Víctor Cespón]

Aissa: the problem is not the controllers. Command View 9.x modifies the metadata on the disks. If you replace the controllers, they will read the metadada on the disks and exactly the same will happen.

Can you explain why you want to use CV 6.0? Current version works with all kinds of EVAs, as long as they have sopported firmware.

[Aissa]

Why you say before it is the NVRAM on the controller that CMD 9xx write on ? and now you say the disk is the "probleme".

I try with no shelf (no disk)attached to the controller uninitilized and i get the same probleme.

It is a money probleme ........ waiting for the budget to go on.

[Torsten.]

All the metadata are in controller memory and written to the disks. When starting, these values will be read from disks. For this reason a controller replacement will likely not help. There are probably ways to really "scrub" the metadata, but in this case your data cannot survive.

[Aissa]

OK thank you for helping me, i'm going to work with 9.1 and reinstall the server eatch 2 months and wait for my boss too buy a license.

Thx

[Torsten.]

nevertheless I would use the latest CV version.
