Create the maximum size bootable volume
Task
When more than 2TiB of disk space is available, use all possible physical disks to create an array, create the
maximum sized boot volume, and then consume the remaining space in another volume.
Hardware configuration
The administrator has an unconfigured system with a controller.
Script
Controller= Slot 1
Array= A
Drive= *
LogicalDrive=1 ; consumes the first 2TiB
RAID= 0
Size= MAXMBR
LogicalDrive=2 ; consumes remainder of free space
RAID=0
Summary
Without specifying drives by name, the administrator instructs the controller to use available disk space, up
to 2TiB, to create the first volume in an array. Any remaining disk space is consumed in a second volume
automatically.
Create a configuration with a specific block size
Task
Identify the size of a logical volume in blocks, and then create a configuration for another logical volume that
matches exactly, using block size instead of capacity.
Currently, all RAID Controller volumes consist of 512-byte blocks. When you create a custom configuration
that uses the Size parameter, the script specifies the input size in MiB, which rounds the requested value
into some number of blocks equal to or slightly greater than the requested size; the exact value depends on
the array configuration.
However, if you use the SizeBlocks parameter to create the logical volume, then the script specifies the input
size in the exact number of blocks, and no rounding occurs. In some cases, the RAID configuration might
adjust the number of blocks in the new logical drive.
Hardware configuration
The administrator has a system with a controller and a configured logical volume.
Script output
To identify the size of an existing logical volume, in blocks, observe the output when you capture the existing
configuration. Scripting outputs the current size of volumes in block units in a comment.
; Logical Drive Specifications
LogicalDrive= 2
RAID= 5
Size= 279964
; SizeBlocks= 573367088
Sectors= 32
StripSize= 512
Caching= Enabled
You can then use the size, specified in blocks, to configure another logical volume that is an exact match in
size. When using an input script, you can specify either Size or SizeBlocks, but not both.
