                                    //Create virtual disk on a disk group created by

                                    is created using all remaining capacity by
                                    omitting the capacity=virtualDiskCapacity parameter

                                    set virtualDisk["7"] consistencyCheckEnabled=false;
                                    set virtualDisk["7"] modificationPriority=high;
                                 

This example shows blank lines between the lines beginning with Show, Create, //Note, and create. The blank lines are included in this example only for clarity. Each command is actually written on one line in the script file; however, the size of this page causes the command text to wrap. You might want to include blank lines in your script files to separate blocks of commands or make a comment more outstanding. You can do this by entering two forward slashes (//), which causes the script engine to treat the line as a comment.

The first line of text is the show string command. This command displays text bounded by quotation marks (" ") on a monitor screen when the script file runs. In this example, the text Create RAID 5 Virtual Disk 7 on existing Disk Group 1 serves as a title describing the expected results of running this script file.

The line beginning //Create is a comment explaining that the purpose of this script file is to create a new virtual disk by using the create virtualDisk command on an existing disk group.

The line beginning //Note: is a comment in the script file explaining that the size of the last virtual disk created uses all of the available capacity because the capacity parameter is not used.

The command in this example creates a new virtual disk in disk group 1. The virtual disk has a redundant array of independent disks (RAID) level of 5. The virtual disk name (user label) is 7. (Note the quotation marks around the 7. The quotation marks indicate that the information in the marks is a label.) The new virtual disk is assigned to the RAID controller module in slot 0 in the RAID enclosure. The segment size is set to 16.

create virtualDisk diskGroup=
                                    diskGroupNumber
                                    userLabel="
                                    virtualDiskName" [freeCapacityArea=
                                    
                                    freeCapacityIndexNumber] [capacity=
                                    
                                    virtualDiskCapacity | owner=(0 | 1) | segmentSize=
                                    
                                    segmentSizeValue]
                                    [enclosureLossProtect=(TRUE | FALSE)]
                                 

The line show "Setting additional attributes for virtual disk 7" is another example of using the show string command. This command is placed here to tell you that the create virtualDisk command ran successfully. In addition, properties that could not be set by the create virtualDisk command are now set.

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.
