container Commands
container split
To split a mirror set or a multilevel array of mirror sets into two
separate single-partition volume sets or two multilevel arrays of
single-partition volume sets, use the container split
command. Once this command completes execution, the two
volume sets cannot be merged.
Before using this command to split an array, shut down system
applications (such as, databases) in order to flush application data
to the controller.
When you split a mirror set or a multilevel array of mirror sets, the
system creates a new (referred to as the split) array. The split array
contains half of the storage data from the original (referred to as the
master) array (mirror set). In addition, the split array has an
identical copy of the data from the old disk at the time of the split
operation.
In Windows, the split array’s file system may be inconsistent and
you should verify and repair it as follows:
■ Assign a drive letter to the split array using the container
assign drive_letter
command.
■ Run the DOS CHKDSK command with the /F switch. For
details, refer to your Windows documentation.
On UnixWare, before splitting a mirror set that contains a volume
table of contents, run the edvtoc command and change the
volume label to a series of twelve spaces. You can then use the
container split
command to split the mirror set.
Syntax
container split {container}
Parameters
{container}
Specifies the ID number (0 to 63) of the array (mirror set or
multilevel array of mirror sets) to split into two separate arrays.
