How would my host responds if it happend to pick this WD device as GK?

Why VCM device is Not coming under PP control like other devices?

Is it OK to make them WR and use as GK?

How can i put them under GKavoid or skip list?

Re: VCM GK not under PP and WD

Hello.  This is expected behavior with the VCM bit enabled, the gatekeeper devices are not a multipath device type, so PowerPath will not manage them.  The same is true for CLARiiON LUNZ devices.  I hope this helps.

Thanks, Brion
