Displaying a list of checkpoints

VVR enables you to get a list of the Primary checkpoints using the vxrvg cplist command; the vxrlink cplist command enables you to get a list of the Secondary checkpoints. The vxrvg cplist and vxrlink cplist commands can be run on the Primary only. VVR supports a maximum of 46 checkpoints, and hence the list displays a maximum of 46 checkpoints. If you try to create more than the specified number of checkpoints, an error message prompts you to delete older checkpoints before creating new checkpoints.

Primary checkpoints are created using the vxrvg -c checkpoint_name checkstart command on the Primary and are associated with an RVG. Issue the vxrvg cplist command to display a list of the existing Primary checkpoints associated with the specified RVG. The Primary checkpoints can be deleted using the
vxrvg -c checkpoint_name checkdelete rvg_name command.

Secondary checkpoints are created using the vxrlink -c checkpoint_name pause command on the Secondary and are associated with the RLINK. Issue the vxrlink cplist command on the Primary to display a list of the existing Secondary checkpoints associated with the specified RLINK. The Secondary checkpoint can be deleted by using the vxrlink -c checkpoint_name checkdelete rlink_name command.


  Note   The vxrlink cplist command and the vxrlink checkdelete command must be run on the Primary only.


The displayed information includes details about each checkpoint, such as checkpoint name, size, percentage of SRL used, and whether the checkpoint has been started or completed. If the SRL usage reaches 100%, the checkpoint overflows and becomes unusable. In this case, VVR displays the message Checkpoint overflowed.

To display a list of Primary checkpoints, enter the following command on the Primary:

# vxrvg -g diskgroup cplist rvg_name

To display a list of Secondary checkpoints, enter the following command on the Primary:

# vxrlink -g diskgroup cplist rlink_name

where rlink_name is the name of the Primary RLINK that connects to the Secondary where the vxrlink -c checkpoint_name pause was issued. The output resembles:

Name MBytes % Log Started/Completed

---- ------ ------ -----------------

a8 200 5 Completed
a9 800 20 Completed
a6 2000 40 Started
