#E2800 controller replacement: do WWPNs carry over?

We're replacing an E2800 controller. We're moving over the Host Interface Card from the failed controller, however the SAN was connected to the controller's ports, not the HIC.
Will the onboard ports get the original WWPNs re-programmed to it when we bring it up?

#

The service guide doesn't say anything about this, aside from the case of adding a second controller to a single-controller configuration.

no, WWPNs will not carry over

lean warren
#

Hmm. Except it appears we have all four paths back.

#

(Will have to verify that now... I don't have access to see the host side)

#

ah wait you're doing a hardware replacement? sorry I think I misunderstood your post then. Yes, for a hardware replacement, the WWPNs will carry over

#

sorry for the confusion

lean warren
#

Yes, controller failed, so it's a replacement

#

(not an upgrade/migration swap)

#

And it does appear to look right on the SAN side

But thank you for replying, @wary mural .

#

We're onto a completely different issue, going on 3.5 hours wait for a callback with Support. Yes, it's been escalated.

@lean warren did you get connected?

Ok good.

Which hasn't materialized yet, but things are stable so I can't justify escalating the severity. I get the feeling there aren't a lot of support people who really know the insides of E-series.

So it's Web interface will not start. Meaning we can't failover to Controller A so we can replace Controller B (they both had worn-out cache SSDs). But both are serving data fine.
