A primary uses for BCV copies (TimeFinder mirroring) can include restoring the standard device with the existing BCV copy. This procedure describes how to perform the restore TimeFinder (BCV) pair operation.


This procedure is based on content from the following EMC manual:

Verify the BCV pair is split

To verify the BCV device is completely split from the standard, use the query action as follows:


symmir –g DgName query DEV001




Restore the standard devices

When restoring existing pairs, the best practice is to restore only changed tracks with an incremental restore. If restoring with a new pairing not previously synchronized, you have to specify the –full option. Use the –protect option to write protect the BCV. To incrementally restore the entire device group or standard devices, enter:


symmir –g DgName restore -protect


Or to target the incremental restore (changed tracks only) to a specific BCV pair device (e.g. DEV001), enter:


symmir –g DgName restore –protect DEV001


Or to target a full restore (for new pairing) to a specific BCV pair device (DEV001 for example), enter:


symmir –g DgName restore –protect DEV001 bcv ld BCV001




Verify the restore operation completes

To verify when the standard device(s) are completely restored from the BCV copy, use the verify action as follows:


symmir –g DgName –i 10 verify –restored


With this interval and count, the message is displayed every 10 seconds until the pair is restored.
