Fibre link down not causing a failover
have 2 controllers in a MSA 1500, when i pull the fibre conection out of the switch that goes to the active controller the link state goes down on the controller but the controller does not fail over.... is this correct.. i would expect a controller to failover if it no longer had a good fibre link??

Re: Fibre link down not causing a failover
According to HP, your multipath software is what actually initiates the failover process in the case of a fibre failure. Are you attempting this with active hosts on the MSA? or just in a testing phase?
You can manually initiate a failver by removing the active controller. HP also does not recommend doing this with active hosts, rather use Secure Path Manager to fail paths. In the case of MPIO, I am not sure how you would manually test since MPIO has no manager. Pulling the fibre though should be sufficent.

Re: Fibre link down not causing a failover
It should apply to the MSA1500 as well since, well... the controllers are the same.

Re: Fibre link down not causing a failover
with the MPIO driver installed the failover did occur... i just thought the controllers themselves would be able to iniciate a fallover.
the same test now is working, thanks
