316 Sample Script Files
The set virtualDisk command parameters are shown on separate lines. You do
not need to use separate lines for each parameter. You can enter more than
one parameter with the set virtualDisk command by leaving a space between
the parameters.
By using separate lines, however, you can more clearly see what parameters
you are setting and the values to which you are setting the parameters.
Blocking the parameters in this manner makes it easier to edit the file or copy
specific parameter settings for use in another script file.
Configuration Script Example 2
This example creates a new virtual disk using the create virtualDisk
command with user-defined physical disks in the storage array.
Show "Create RAID 5 Virtual Disk 2 on existing
Disk Group 2";
//This command creates the disk group and the
initial virtual disk on that group.
//Note: For disk groups that use all available
capacity, the last virtual disk on the group is
created using all remaining capacity by omitting
the capacity=virtualDisk creation parameter
create virtualDisk raidLevel=5 userLabel="2"
physicalDisks=[0,1 0,6 1,7 1,3 2,3 2,6] owner=1
segmentSize=16 capacity=2GB;
show "Setting additional attributes for virtual
disk 7";
//Configuration settings that cannot be set during
virtual disk creation
set virtualDisk["7"] mediaScanEnabled=false;
set virtualDisk["7"] consistencyCheckEnabled=
false;
set virtualDisk["7"] modificationPriority=high;

Details CLI parameters like host-name-or-IP-address, -A, -a, and their definitions.

About the Script Commands

Script Command Synopsis

Lists general script command categories like activate, autoConfigure, check, clear, create, etc.

Configuring a Storage Array

Saving a Configuration to a File

Details how to save the current storage array configuration to a script file for backup or restoration.

Using the Create Virtual Disk Command

Explains how to create new virtual disks in three different ways: manual, software-assigned, or in existing groups.

Using the Auto Configure Command

Describes the command to automatically configure disk groups, virtual disks, and hot spares for the storage array.

Modifying Your Configuration

Explains how to modify configuration properties like passwords, alerts, and RAID controller settings using `set` commands.

Setting the Storage Array Password

Details how to define a password for a storage array to enhance security and prevent destructive commands.

Using the Snapshot Feature
