<program-directory>\bin\swstestupdate start Volume-Name

When looking up the update volume (displaying the status of the pseudo session)

<program-directory>\bin\swstestupdate status Volume-Name

When finishing update volume measurements (cancelling the pseudo session)

<program-directory>\bin\swstestupdate stop Volume-Name

DESCRIPTION

This command measures the physical capacity of a Snap Data Volume using the pseudo session setting function.

When starting update volume measurements (setting up a pseudo session)

Specify "start" as the subcommand to start measure of the physical capacity of a Snap Data Volume.

When looking up the update volume (displaying the status of the pseudo session)

Specify "status" as the subcommand to display the physical capacity of a Snap Data Volume.
The following information will be displayed:

Title	Description
Volume-Name	The volume name.
Update	The amount of data that has been updated since measurements started in the number of blocks (1 block = 512 bytes). Displays "----" if there is no pseudo session. Displays "failed" if the pseudo session is error-suspended.

When finishing update volume measurements (cancelling the pseudo session)

Specify "stop" as the subcommand to stop measure of the physical capacity of a Snap Data Volume

• Specifies the volume name.
  Specify a copy source volume that is used with SnapOPC/SnapOPC+ operations

  
  

EXIT STATUS

=0: Completed successfully
>0: Terminated abnormally

EXAMPLES

• Measure the update volume:

  (Start taking measurements by starting a pseudo SnapOPC/SnapOPC+)  
  C:\>C:\Win32App\AdvancedCopyManager\bin\swstestupdate start g1d1p1
  g1d1p1 swstestupdate completed
  
  (First measurement)
  C:\>C:\Win32App\AdvancedCopyManager\bin\swstestupdate status g1d1p1
  Volume-Name Update
  g1d1p1      644333
  
  (Second measurement)
  C:\>C:\Win32App\AdvancedCopyManager\bin\swstestupdate status g1d1p1
  Volume-Name Update
  g1d1p1      1045000
  
  (Stop taking measurements by cancelling the pseudo SnapOPC/SnapOPC+)
  C:\>C:\Win32App\AdvancedCopyManager\bin\swstestupdate stop g1d1p1
  g1d1p1 swstestupdate completed
  C:\>

  
  

NOTES

• The amount of data updated cannot be measured in the following cases:

  • When the specified volume does not exist.

  • When the ETERNUS Disk storage system device does not support the SnapOPC/SnapOPC+ function.

  • When the pseudo session has already been set up (i.e., when the "start" option is specified).

  • When the pseudo session does not exist (i.e., when the "stop" option is specified).
