Probably there were two problems, my mistake and then some desynchronisation of both controllers. We must completely purge all configuration from both controllers and reinitialize again. Co-pilots worked relatively hard but passed. For myself it was some kind of school. It seems that Compellent IS really different solution. I am in progress of testing features and performance. After this fix I already tested something. And seems interesting.
we are in progress of testing Scv3020. I initialized the array, I login into Storage center. But I tried to cleanup drive configuration (I want to configure all from scratch). I released all rotational drives. Result is that both controllers are orange and I am not able to login to Storage center again. I understanded that there are probably portion of OS on the drives. And question is easy, how to resolve this. (it seems that on controllers are some services failing, OS itself booted) I expect that it will require some kind of service login and then array will be completely purged and reverted to default (there are still no data on it so absolutely no problem with this setup) But how? I didn´t find some service document with these tasks and also service support password. Probably tech-support can do this. Or is there another way?
