EVA 4100 controller mastership
We have in our EVA4100 the continuous change of controller mastership, day in day out, every X hours; is it caused by the battery?
see logs, at the end battery logging

Re: EVA 4100 controller mastership
A CAC value of 0 means that no action is necessary. It is just an informational message.
You will have to do a traffic analysis to find out which server(s) are causing the ownership transfers.

Re: EVA 4100 controller mastership
From there you need to find out which hosts are causing traffic to the virtual disks which results in ownership transfers. The tools are the Fibre Channel switch performance monitor and the EVAperf utility.

Re: EVA 4100 controller mastership
The eva perf let me see the usage and statistics but why it will change mastership is not obvious, the usage i divided over the 2 contollers because i divided the lun presentation over the 2 controllers manually.

Re: EVA 4100 controller mastership
With EVA, the default is FIXED, with a single ACTIVE path.
Make sure the PREFERRED ACTIVE path of each VMFS volume, ON EACH HOST, is configured to use the same storage controller!
Multiple ESX hosts access the same VMFS volumes. So, if you have multiple VMs on a VMFS volume, and the VMs are running on a different ESX hosts, and the VMFS volume is configured with different paths on your hosts, each time a read/write operation is performed the Vdisk will transfer ownership.
For each VMFS on each host, choose the same preferred path.

Re: EVA 4100 controller mastership
Could this be a scheduled battery load test log ?
