Fully synchronizing STD/BCV mirror pairs

Make sure that each target (BCV) disk is fully synchronized with its source (STD). One way to accomplish this synchronization is as follows.

To fully synchronize STD/BCV mirror pairs

Create a temporary file that contains only the source and target device IDs separated by a space. (Only one source-target pair can exist in a temporary file.)
For example, if the source (STD) device ID is 0050 and the target (BCV) device ID is 0060, the temporary file should contain the following:
```
0050 0060
```
Use the symmir command to fully establish the mirror pair.
```
symmir -sid 000187910258 establish -f temp_file -full
```
When the pair is synchronized, it can be used in a NetBackup policy. Synchronization can take a long time. For example, it may take between 5 and 10 minutes for an 8GB STD/BCV pair to enter the synchronized state.
Check the status of the mirror pair:
```
symmir -sid 000187910258 query -file temp_file
```
Make sure the temp_file name matches the temp_file name you used above.
In the output, look for Synchronized under the State column. When the pair enters the synchronized state, it is ready to be used for backup.
