Question

MSA 2012sa G1 failover

Asked by: davewex

Hi,

I have an MSA2012sa with dual controllers. Controller A is the owner of 2 volumes and B is the owner of another 2. I have MPIO round robin on the server. I have 2 HBAs in the DL380, one HBA to port 1 on each controller.

Controller A failed the other day and B became the preferred owner but the 2 volumes owned by A disappeared from the Windows server. I gave B rw access to B for teh 2 volumes and they appeared.

Going by this both controllers should have rw access to all volumes. Is that correct?  I think I did that before and each volume showed up twice in disk manager in Windows.

What would the best way be to test failover of a controller. I wouldn't like to pull an active controller but can I pull a SAS cable from the HBA in the server? How about shutting the MSA and removing a controller and powering it back on?

one HBA should go to port1 on controller A and the other to port2 on controller B if I remember correctly.

Ownership should fail over automatically, by the looks of it you've manually transferred ownership.

Both HBAs should see the volume but MPIO should sort this out, doesn't sound like MPIO is working if you see them twice.

Sutting down one controller should help with test.

Can you copy/paste the log from the MSA into a text document and I'll look at it tonight, I'm concerned about firmware revision since a MSA 2012i controller crashed with debug error on failover taking not just the volumes on the failed controller offline but crashing the other controller so they all went offline. Firmware update fixed that.

Why have you got this MSA2000 if you've only got one server attached, are you adding another one later?


 

by: davewexPosted on 2009-08-25 at 08:56:09ID: 25178924

As far as I am aware and from looking at HP docs one server with 2 HBA cards must go to the same port number on each controller.

I didn't manually transfer ownership, as stated above B became the preferred owner of the 2 volumes that were originally owned by A. I gave controller B rw access to the volumes and then they appeared.

I am planning on upgrading the firmware when the new controller comes in and the HBA drivers etc.

I have only one server attached as it requires a huge amount of storage space and runs SQL.

I will look into the MPIO issue and will see how it goes. Will keep you posted

You'd probably have been better off with a couple of P800/MSA60s rather than a MSA2000 but there again you've got it now.

Any chance of the log file from the MSA, there isn't an export option but you can copy/paste

looks like controller B didn't have permission to see the volumes and when A failed the volumes went with it. I have given both controllers read write access and that has resolved it
