One assumes that the DR host is different (or why would he be using SRDF?), so this won't be an issue. And why on earth would anyone try and import both sides of the SDRF arrays on the same host at the same time? He'll probably need to force the pool import (with -f), but otherwise should be OK. I will note that due to some proprietary array logic used by EMC, PowerPath will usually be faster than MPxIO if you have multiple FC links. (I _really_ don't line PowerPath, but the numbers in our testing are consistent... we don't see this with our Hitachi arrays and use MPxIO with them). -- Carson _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
