I was thinking about our current practices for SVM- or ZFS-mirrored filesystems on direct-attached drives (incl. jbod). For SVM, the recommended practice has been to use cfgadm to unconfigure a drive before pulling it. My experience with ZFS (as of S10U4) is that one wants to "cfgadm unconfigure" as soon as the drive starts to experience trouble, otherwise ZFS will keep trying and your system may well hang. In fact, many ZFS users have found that ZFS hangs your system if you pull the drive before "cfgadm unconfigure". The point I want to make is that "cfgadm unconfigure" works now on mpt, and MPxIO on mpt causing these devices to disappear from the cfgadm interface is going to take away this capability. Hence the unhappy campers. Regards, Marion _______________________________________________ storage-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/storage-discuss
