Yuck. What an ugly procedure :-( zpool offline is a better method. Identifying the location of the drive is OS, OS rev, and hardware dependent. Some OSes are easier than others. For example in NexentaStor, the device serial numbers are readily displayed, so you can verify the serial number of the disk. MacOS also provides easy access to the disk serial number for verification. When the new disk arrives, do the zpool replace. A detailed method for doing this on Solaris is in the ZFS Admin Guide. -- richard _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
