Using the Virtual Disk Copy Feature 83
• 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.
The following example is the script file version of the command:
show virtualDiskCopy source ["Jaba_Hut"];
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:
