operation. You can ensure that copy-on-write operations maintain a correct 
interval by using this option. The maximum value for the scheduleInterval 
option is 1440 minutes. For example: scheduleInterval=180.

Specific date to stop creating a snapshot (legacy) virtual disk and end the copy-on-
write operations. The format for entering the date is MM:DD:YY, where MM is the 
month, DD the day and YY the year. For example: endDate=11:26:11.

The number of times you want the snapshot schedule to run in a day. For example, 
timesPerDay=4.

Use this parameter to define the time zone in which the storage array is operating. 
You can define the time zone in one of two ways:

• GMT±HH:MM—The time zone offset from Greenwich Mean Time (GMT), in hours 

and minutes. For example, GMT-06:00 is the central time zone in the United 

States.

• Text string—A standard time zone text string, in quotation marks. For 

example, "USA/Chicago" or "Germany/Berlin". Time zone text strings are case 

sensitive. If you enter an incorrect text string GMT is used.

The code string for defining a schedule is similar to these examples:
enableSchedule=true schedule startTime=14:27

enableSchedule=true schedule scheduleInterval=180

enableSchedule=true schedule timeZone=GMT-06:00

enableSchedule=true schedule timeZone="USA/Chicago"

If you also use the scheduleInterval option, the lowest value of the timesPerDay option and the 
scheduleInterval option is used. The firmware calculates an integer value for the 
scheduleInterval option by dividing 1440 by the scheduleInterval option value that you set. For 
example, 1440/180 = 8. The firmware then compares the timesPerDay integer value with the calculated 
scheduleInterval integer value and uses the smaller value.

To remove a schedule, use the delete virtualDisk command with the schedule parameter. The 
delete virtualDisk command with the schedule parameter deletes only the schedule, not the 
snapshot (legacy) virtual disk.

Create Snapshot Virtual Disk

Description

This command creates a snapshot virtual disk for snapshot images of a base virtual disk. You can assign 
the new snapshot virtual disk to an existing repository disk group or disk pool, or you can create a new 
repository disk group or disk pool if one does not already exist.

NOTE: You cannot use this command for a snapshot image that is used in online virtual disk copy.
