Switching plexes to verify the copied data
When the encrypted (target) plexes are first created, the data reads continue to happen from the unencrypted (source) plexes. You can switch the reads to the encrypted plexes to verify that all the original data has been copied.
To read data from the target plex
-
Right-click the top-level volume for which you have started online migration and click Encrypt Volume>Switch plex>Target plex.
-
On the Target plex dialog box, verify the name of the volume and the target plex, and click OK.
This operation invokes the
vxassist migrate command with the -o switchtgt option and the relevant parameters.
-
On the Target plex - Result panel, verify the status of the operation and click OK to close the dialog box.
The encrypted plexes are now set to read-write, and data is read from these plexes. All other plexes are set to write-only.
To read data from the source plex
-
Right-click the top-level volume for which you have started online migration and click Encrypt Volume>Switch plex>Source plex.
-
On the Source plex dialog box, verify the name of the volume and the source plex, and click OK.
This operation invokes the
vxassist migrate command with the -o switchsrc option and the relevant parameters.
-
On the Source plex - Result panel, verify the status of the operation and click OK to close the dialog box.
The unencrypted plexes are now set to read-write, and data is read from these plexes. All other plexes are set to write-only.
Optionally, you can verify the switching of the data reads between source and the target plexes by using the
vxprint command on the InfoScale hosts.
