9.6 Transform Arrays: rcadm --transform
(supported by RAIDXpert2 Plus)
The rcadm --transform or rcadm -T command allows the user to transform (migrate) an
array from one RAID level to almost any other RAID level, and to expand the array dynamically,
even under I/O load.
9.6.1 Before You Begin...
 An array cannot be transformed to a smaller-sized array. New arrays must be either the same
capacity or larger.
 When using the task control option, a Transform can only be paused or resumed but not
removed.
 If a spare has been assigned to the destination array, a fail-over task starts as soon as the
Transform completes, provided the spare is available after the Transform.
 If there are multiple arrays on a single controller, it might not be possible to transform some of
the arrays to a larger size. If the size of an array might be expanded in the future, it is best to
configure the available space as a single array.
 The array size of the transformed array is limited to 2.199 TB on some operating systems.
9.7 Follow or Monitor Arrays and Disks: rcadm --
follow
The rcadm --follow or rcadm -F command allows the user to follow or monitor arrays
and disks. It polls the RAID subsystem for any changes in status and sends an e-mail notification
and/or executes a specified program. The output of this command is logged to the System Event
Log on Windows.
9.7.1 Before You Begin...
It is recommended that the user not run more than one instance of rcadm --follow at the same time.
If the user runs more than one instance of the command, each instance captures some of the events
but no single instance captures all events.
