Replacing HBA on a windows server

Question

One of our windows hosts lost two paths out of four to the CX-500. Changing the cables did not solve the problem. I have asked the admin who owns the host to change the HBA card that lost connectivity.

I was looking around powerlink about replacing HBA cards and came across a primus emc131820 saying EMC support should be contacted. is there a reason for it? Once admin schedules down time, I was going to clear the dead paths on the host side, deregister the old paths from the CX-500, replace the HBA card, update the switch zones with the new HBA and rescan on the host,...and back to business...~:)

is there anything more to it? Just curious why EMC wants us to contact support. is there a know issue on windows?

Thanks in advance.

On the Clariion side you must also register the new paths under the existing host's information (connectivity status, register, and register then to the existing host).

After replacement of an HBA, the new registered initiator path(s) will NOT be added to the Storage Group. The new initiator(s) must be brought into the Storage Group to allow access to the LUNs.

Follow these steps:

Open Navisphere Manager and verify you're in the Storage Tab.
Expand the array and then the Hosts section.
Right-click the host having the problem and click Connectivity Status.
You will see the initiators that need to be added as they will show up in ~management.
Click Reconnect to have them added to the Storage Group.
Now run whatever procedures are necessary to have the host recognize the devices down the new HBA.

I would first verify the above reconnect procedure is there in you version of flare. Just follow the steps and see if that reconnect button is in that window. If not, then I can put in another procedure.

Primus emc207351 is sited above.

That's kind of funny, maybe it is for admins that don't know what to do when replacing an HBA?

Just ensure that you modify the zones for the old HBA with the WWN for the new HBA and update the connections in Navisphere.

Thanks Aran and Ryan!Ryan, Yes, I have the 'reconnect' option. I am on flare 2.26

Ryan, May be that is the reason....BUT I think referring to the primus you gave previously (emc207351 ) would have been enough instead of 'call EMC now....'..~:)Thank you,

Thinking back about the 'please contact EMC' thing, I think it has to do with verifying that all paths from that host get added to the storage group after you replace the HBA. You can do this by going into connectivity status from the host itself in the procedure. If it was supposed to have 4 paths and you see 4 paths in the storage group (via connectivity status) then your fine.-Ryan

I think it's a 'disclaimer' kind of message - if you understand all the steps you really don't need to call us - I'll see if we can modify the statement a bit to make this clearer.glen
