controller Commands
controller rescan
To rescan the SCSI channels on the currently opened controller and
update all underlying structures, use the controller rescan
command. The effect of this command is to verify currently
connected disks or to recognize new disks added to the channel.
This command rescans the disks for the arrays and loads the
volatile array and the partition tables from disks again. If nothing
on the disks has changed, controller rescan should have no
visible effect. However, if any disk partition structures have
changed, this command causes those changes to be reflected in the
array and partition lists in the controller memory. If you add disks
to the controller, the rescan enables you to use those disks.
