See step 1 to step 4 in Preparing Host Servers To Create A Virtual Disk Copy. The create virtualDiskCopy command might look like the following example: client>smcli 123.45.67.89 -c "create virtualDiskcopy source=\"Jaba_Hut\" target= \"Obi_1\" copyPriority=medium targetreadonlyenabled=true" The command in this example copies the data from the source virtual disk named Jaba_Hut to the target virtual disk named Obi_1. Setting the copy priority to medium provides a compromise between the following storage array operations: • The speed with which the data is copied from the source virtual disk to the target virtual disk • The amount of processing resource required for data transfers to other virtual disks in the storage array Setting the targetReadOnlyEnabled parameter to TRUE means that write requests cannot be made to the target virtual disk. This setting also ensures that the data on the target virtual disk remains unaltered. Refer to steps 1 through 4 in the preceding section, Preparing Host Servers To Create A Virtual Disk Copy. The following example is the script file version of the command: create virtualDiskcopy source="Jaba_Hut" target= "Obi_1" copyPriority=medium targetreadonlyenabled=true; After the virtual disk copy operation is completed, the target virtual disk automatically becomes read-only to the hosts. Any write requests to the target virtual disk are rejected, unless you disable the read-only attribute. Use the set virtualDiskCopy command to disable the read-only attribute. Viewing Virtual Disk Copy Properties Using the show virtualDiskCopy command, you can view information about one or more selected source virtual disks or target virtual disks. This command returns the following information: • The virtual disk role (target or source) • The copy status • The start timestamp • The completion timestamp • The virtual disk copy priority • The read-only attribute setting for the target virtual disk • The source virtual disk World Wide Identifier (WWID) or the target virtual disk WWID A virtual disk can be a source virtual disk for one virtual disk copy and a target virtual disk for another virtual disk copy. If a virtual disk participates in more than one virtual disk copy, the details are repeated for each associated copy pair. The following syntax is the general form of the command: show virtualDiskCopy (allVirtualDisks | source [sourceName] | target [targetName]) The following example shows a command that returns information about a virtual disk used for a virtual disk copy: client>smcli 123.45.67.89 -c "show virtualDiskCopy source [\"Jaba_Hut\"];" The command in the preceding example requests information about the source virtual disk Jaba_Hut. If you want information about all virtual disks, use the allVirtualDisks parameter. You can also request information about a specific target virtual disk. 60

See step 1 to step 4 in Preparing Host Servers To Create A Virtual Disk Copy.
The
create virtualDiskCopy
command might look like the following example:
client>smcli 123.45.67.89 -c "create
virtualDiskcopy source=\"Jaba_Hut\" target=
\"Obi_1\" copyPriority=medium
targetreadonlyenabled=true"
The command in this example copies the data from the source virtual disk named
Jaba_Hut
to the target virtual disk
named
Obi_1
. Setting the copy priority to medium provides a compromise between the following storage array
operations:
•
The speed with which the data is copied from the source virtual disk to the target virtual disk
•
The amount of processing resource required for data transfers to other virtual disks in the storage array
Setting the
targetReadOnlyEnabled
parameter to
TRUE
means that write requests cannot be made to the target
virtual disk. This setting also ensures that the data on the target virtual disk remains unaltered.
Refer to steps 1 through 4 in the preceding section, Preparing Host Servers To Create A Virtual Disk Copy. The following
example is the script file version of the command:
create virtualDiskcopy source="Jaba_Hut" target=
"Obi_1" copyPriority=medium targetreadonlyenabled=true;
After the virtual disk copy operation is completed, the target virtual disk automatically becomes read-only to the hosts.
Any write requests to the target virtual disk are rejected, unless you disable the read-only attribute. Use the
set
virtualDiskCopy
command to disable the read-only attribute.
Viewing Virtual Disk Copy Properties
Using the
show virtualDiskCopy
command, you can view information about one or more selected source virtual
disks or target virtual disks. This command returns the following information:
•
The virtual disk role (target or source)
•
The copy status
•
The start timestamp
•
The completion timestamp
•
The virtual disk copy priority
•
The read-only attribute setting for the target virtual disk
•
The source virtual disk World Wide Identifier (WWID) or the target virtual disk WWID
A virtual disk can be a source virtual disk for one virtual disk copy and a target virtual disk for another virtual disk copy.
If a virtual disk participates in more than one virtual disk copy, the details are repeated for each associated copy pair.
The following syntax is the general form of the command:
show virtualDiskCopy (allVirtualDisks | source
[sourceName] | target [targetName])
The following example shows a command that returns information about a virtual disk used for a virtual disk copy:
client>smcli 123.45.67.89 -c "show virtualDiskCopy
source [\"Jaba_Hut\"];"
The command in the preceding example requests information about the source virtual disk
Jaba_Hut
. If you want
information about all virtual disks, use the
allVirtualDisks
parameter. You can also request information about a
specific target virtual disk.
