84 Using the Virtual Disk Copy Feature
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;
Recopying a Virtual Disk
NOTICE: The recopy virtualDiskCopy command overwrites existing data on the
target virtual disk and makes the target virtual disk read-only to hosts. The recopy
virtualDiskCopy command fails all snapshot virtual disks associated with the target
virtual disk, if any exist.
