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

Primary Storage 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 Storage Checkpoints associated with the specified RVG. The Primary Storage Checkpoints can be deleted using the vxrvg -c checkpoint_name checkdelete rvg_name command.

Secondary Storage 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 Storage Checkpoints associated with the specified RLINK. The Secondary Storage Checkpoint can be deleted by using the vxrlink -c checkpoint_name checkdelete rlink_name command.

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

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

# vxrvg -g diskgroup cplist rvg_name

To display a list of Secondary Storage 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
