Add a simple volume on systems with mixed controller and physical disk configurations
Task
Add a simple, one-disk RAID 0 volume on each system, using one script. However, do not add a new volume
to systems booting from an external controller.
Hardware configuration
The administrator has 500 systems, some with embedded controllers, some with controllers in expansion
slots, and some booting from an external controller.
Each system has a different physical disk configuration, some disks in an internal drive cage and some in an
external storage box. Each system can have a different number of arrays and volumes.
Script
# ssascripting -i input.txt – internal
Controller=First
Array=Next
Drive=1
LogicalDrive=Next
RAID=0
Summary
By combining the advanced commands to specify -internal controllers only, and then First controllers, the
user does not add volumes to external controllers or to additional internal controllers on the same system.
The Next command eliminates the need to identify specific arrays and volumes.
Create multiple arrays on unconfigured systems with mixed physical disk configurations
Task
Add two arrays, each with one volume, to each system. Configure the first array as an OS volume with RAID 1
and a single spare. Configure the second array to use all remaining disks in a RAID 5 volume with no spares.
Hardware configuration
The administrator has 500 unconfigured systems with embedded controllers. Each system has a different
physical disk configuration, some disks in an internal drive cage and some in an external storage box.
Script
Controller=Slot0
Array=A
Drive=2
OnlineSpare=1
LogicalDrive=1
RAID=1
Array=B
Drive=*
LogicalDrive=2
RAID=5
Summary
The Slot0 specification targets embedded controllers only. Each array is configured using available drives.
Array A uses two available drives, and the script eliminates the need to specify the drives by address. Array B
uses all remaining available drives, again without specific drive addresses, but also without the administrator
having to specify the number of drives, which can vary for each system.
