Using the Virtual Disk Copy Feature
85
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.
NOTE:
Removing the drive letter of the associated virtual disk(s) in Windows or
unmounting the virtual drive in Linux helps to guarantee a stable copy of the drive
for the virtual disk copy.
Before creating a new virtual disk copy for an existing copy pair, both the
server and the associated virtual disk you are recopying have to be in the
proper state. To ensure that the host server is properly prepared to create a
virtual disk recopy, you can either use an application to carry out this task, or
you can perform the following steps:
