Thanks for your help. It solved the main issue and now we could create the mirror.
We have one more issue left. We have 2 SAN switches and 2 storages.
- Storage1 Controller A 2nd port and Storage2 Controller A 2nd port is connected to switch1 zone2.
- Storage1 Controller B 2nd port and Storage2 Controller B 2nd port is connected to switch2 zone2.
- 1st port on each controller are connected to zone 1 on both switches
- switches are not connected directly to each other
When we simulate a disaster and turn off a switch1(where controller A ports connected), and Volume is owned by ControllerB, the controller change does not happen and the mirror fails.
After a manual controller change it starts to work.
We experienced it in normal operation when ownership loadbalance was enabled and when the ownership changed automatically on the primary volume, but not on the secondary, the mirror stopped. Manually change the owner of the volume on both storages solves the issue
Do you have an idea what can be the reason ?
