If there are more than one SCSI controllers on your machine - there are disks from each controller - is there an option within ZFS to create a mirror of an existing pool so that sub mirror is picked from different controller than that of the initial one, instead of leaving this to admin or a cronjob to decide a best disk for the mirroring?
more details:
current OS booted pool:
consists of OSpool: c0t0d0 -- I have the following disks to choose a sub mirror
c1t0d0 , c2t0d0 , c0t0d1
wouldn't it be good if zpool had an option to choose the best disk for the mirror . this will help in breaking and readding the mirrors again in future for any maintenance so that consistency is not lost. vxvm does something like this
