This command creates a VolumeCopy and starts the VolumeCopy operation.
Important:
You can have a maximum of eight VolumeCopies in progress at one time. If you try to create more than eight VolumeCopies at one time, the controllers return a status of Pending until one of the VolumeCopies that is in progress finishes and returns a status of Complete.
create volumeCopy source=”sourceName” target=”targetName” [copyPriority=(highest | high | medium | low | lowest) targetReadOnlyEnabled=(TRUE | FALSE)]
Parameter | Description |
---|---|
source | The name of an existing logical drive that you want to use as the source logical drive. Enclose the source logical drive name in double quotation marks (“ ”). |
target | The name of an existing logical drive that you want to use as the target logical drive. Enclose the target logical drive name in double quotation marks (“ ”). |
copyPriority | The priority that VolumeCopy has relative to host I/O activity. Valid values are highest, high, medium, low, or lowest. |
targetReadOnlyEnabled | The setting so that you can write to the target logical drive or only read from the target logical drive. To write to the target logical drive, set this parameter to FALSE. To prevent writing to the target logical drive, set this parameter to TRUE. |
You can use any combination of alphanumeric characters, hyphens, and underscores for the names. Names can have a maximum of 30 characters.
Copy priority defines the amount of system resources that are used to copy the data between the source logical drive and the target logical drive of a VolumeCopy pair. If you select the highest priority level, the VolumeCopy uses the most system resources to perform VolumeCopy, which decreases performance for host data transfers.
