Yes, the MSA2050 JBOD enclosure is hot pluggable. Be sure you follow all the recommended guides on racking and power. Once the enclosure is properly installed you can simple insert the SAS cables, allow the MSA2040 time to scan the backend and add the new drives.
Once the new drives have been discovered you can use the MSA2040 SMU or the MSA2040 CLI. You cannot connect to the MSA2050 JBOD enclosure and configure the new drives.
Never suggested to manually execute rescan command when production is up. Let the system scan drives automatically.
Hope this helps!
