Hi,
my company purchased a new storage array, and i need to migrate data
from the old array to the new one.
i'd like to know if there is a way to migrate the data online, with
host-based mirroring.
can i add a new volume or set of volumes to an existing volume group,
perform a mirror and disconnect the old volumes without downtime?

instructions will be very appreciated.
thanks,
yaron

Depending from the AIX version and Disk size the steps are
1) add the new disk to the current Volume Group (VG)
$ man extendvg
2) migrate the data to the new disk - disk or lv based
$ man migratepv
3) Remove the old disk from the VG
$ man reducevg
