EVA5000 controller replacement

When replacing one of the controllers in eva5000 we had a new wwn and serial number thus making it very complex to update all secure path configurations.
Does anyone know of an 'easy' way to do this?

Re: EVA5000 controller replacement

Hi,
it can be done online with the following conditions:
a) off peak hours
b) perform the SecurePath failover to the remaining controller before the "bad" controller replacement

the pain is one part of the reality

Re: EVA5000 controller replacement

not to forget on the step c) :-)
c) if you have any single path hosts, which are connected only to the failed EVA controller, they should be shut down.

Re: EVA5000 controller replacement

A new WWN? Did you reinitialize the EVA?
The front-end WWPNs are a soft-item and should have been retained from the meta-data. Or did the controllers somehow swap them?

Re: EVA5000 controller replacement

Some clarification:
The replacement was done the standard way, shutdown controller B ( in this case ) and replace it.
The problem we had was that the new controller had, of course, different serial number and WWPN's so we should have to rebuild the Secure Patch configuration files as they holds the old controllers data.

Re: EVA5000 controller replacement

Hi,

That shouldn't have happened... The WWN is stored on the disks rather than the controllers.

A controller replacement *should* be completely transparent to the connected hosts. I've done a couple and didn't have to change anything on the host side - although I was never using SecurePath...

Cheers,

Re: EVA5000 controller replacement

Hi There,

Tend to agree with the above comments. Check out this HP website for how to replace a EVA5000 controller, of any EVA part for that matter [and anything else HP!]:

http://h20181.www2.hp.com/plmcontent/NACSC/SML/

Just keep following the storage links till you get to what you require - nice videos and written instructions on "how to".

Re: EVA5000 controller replacement

The problem is the serial number changing when replacing a controller and Secure Path is not able to 'pick it up'
It needs a reconfig.

Thanks for all replies

Re: EVA5000 controller replacement

The HP Partner Portal has changed much since then...

Is there a better link to a document that describes the controller change??
