Yeh . Thank Phil . it is quite useful . Now we see there are two options . 1) without metadata 2) externally managed metadata . But we would like to keep the metadata external to mirror leg ( like on host local drive ) for the reasons mentioned below , not the externally managed metadata , just by keeping metadata on mirror legs . Do we have any option with md driver ?
I'm not sure I understand your follow-up question. You've restated my answer, and re-iterated your preference to not have metadata on the member devices. So you need to write a service to handle metadata the way you want. Or write scripts that will do --build operations at appropriate times without metadata. I'm not entirely clear why the on-member metadata is unacceptable, but as such, either remaining option needs some code of your own. Phil
