At this point, a storage snapshot can be taken from the donor system.
Execute the following command to close and open the tables in read only mode:
FLUSH TABLES WITH READ LOCK;
mysql> FLUSH TABLES WITH READ LOCK;
Query OK, 0 rows affected (0.00 sec)
Once the tables have been locked, login to the FlashArray Graphical user interface, navigating to the Storage View, and select Volumes. Identify the volume which is attached to the source system (in this case it is called DB-09-MariaDB) and select it.
Once in the specific volume view identify the Volume Snapshots area and select + to create a Volume Snapshot.
Give the volume snapshot an optional suffix if required and then select Create.
The volume snapshot will show up for the specific volume.
Once the volume snapshot has been created the tables on the source can be unlocked using the unlock tables command.
unlock tables;
