Using the Virtual Disk Copy Feature
87
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
CAUTION:
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.
Using the
recopy virtualDiskCopy
command, you can create a new virtual
disk copy for a previously defined copy pair that has a status of Stopped,
Failed, or Completed. Use the
recopy virtualDiskCopy
command to create
backups of the target virtual disk, then copy the backup to tape for off-site
storage. When using the
recopy virtualDiskCopy
command to make a
backup, you cannot write to source while the recopy is running. The recopy
might take a long time.
When you run the
recopy virtualDiskCopy c
ommand, the data on the source
virtual disk is copied in its entirety to the target virtual disk.
Reset the copy priority for the recopy operation by using the
recopy
virtualDiskCopy
command. The higher priorities allocate storage array
resources to the virtual disk copy at the expense of storage array performance.
Preparing Host Servers to Recopy a Virtual Disk
CAUTION:
Before you create a new copy of a source virtual disk, stop any data
access (I/O) activity or suspend data transfer to the source virtual disk (and, if
applicable, the target disk) to ensure that you capture an accurate point-in-time
image of the source virtual disk. Close all applications, including Windows
Internet Explorer, to make sure all I/O activity has stopped.
