Changing Virtual Disk Copy Settings
The
set virtualDiskCopy
command enables you to change the property settings for a virtual disk copy pair.
Using this command, you can change the following items:
• Copy priority
• Read/write permission for the target virtual disk
Copy priority has five relative settings, which range from highest to lowest. The highest priority supports the virtual disk
copy, but I/O activity might be affected. The lowest priority supports I/O activity, but the virtual disk copy takes longer.
You can change the copy priority at three different times in the operation:
• Before the virtual disk copy begins
• While the virtual disk copy has a status of In Progress
• After the virtual disk copy has completed re-creating a virtual disk copy using the
recopy
virtualDiskCopy
command
When you create a virtual disk copy pair and after the original virtual disk copy has completed, the target virtual disk is
automatically defined as read-only to the hosts. The read-only status of the target virtual disk ensures that the copied
data on the target virtual disk is not corrupted by additional writes to the target virtual disk after the virtual disk copy is
created. Maintain the read-only status when the following conditions apply:
• You are using the target virtual disk for backup purposes
• You are copying data from one disk group to a larger disk group for greater accessibility
• You are planning to use the data on the target virtual disk to copy back to the source virtual disk in case of a
disabled or failed snapshot virtual disk
At other times you might want to write additional data to the target virtual disk. You can use the
set
virtualDiskCopy
command to reset the read/write permission for the target virtual disk.
NOTE: If you enabled host writes to the target virtual disk, read and write requests are rejected while the virtual
disk copy has a status of In Progress, Pending, or Failed.
The following syntax is the general form of the command:
set virtualDiskCopy target [targetName] [source
[sourceName]] copyPriority=(highest | high |
medium | low | lowest) targetReadOnlyEnabled=(TRUE | FALSE)
NOTE: Use one or both of the parameters as needed to help define your configuration. It is not necessary to use
either parameter.
The following example shows how to change parameters using the
set virtualDiskCopy
command:
client>smcli 123.45.67.89 -c "set virtualDiskcopy
target [\"Obi_1\"] copyPriority=highest
targetreadonlyenabled=false;"
The following example is the script file version of the command:
set virtualDiskcopy target ["Obi_1"] copyPriority=
highest targetreadonlyenabled=false;
