This will now require a separate section "Use Cases". This was originally within "Problem description", but use cases seems to be missed when it was filled out. This will hopefully improve spec submission. Change-Id: I3615ca5ff5c46851e682739a8343242e2f1b0a8d

Use Cases
Proposed change
- FC Support
-
Add a new driver class.
- FC Auto Zoning Support
-
Add logic in intialize_connection() and terminate_connection() according to blueprint https://blueprints.launchpad.net/cinder/+spec/cinder-fc-zone-manager and the fix for bug https://bugs.launchpad.net/cinder/+bug/1308318.
- Read-only Volume Support
-
Add logic in intialize_connection() according to blueprint https://blueprints.launchpad.net/cinder/+spec/read-only-volumes.
- External Volume Management Suppport
-
Implement driver API according to blueprint https://blueprints.launchpad.net/cinder/+spec/add-export-import-volumes.
- Advance LUN Features
-
Add logic to support more extra spec key-value pairs
- Initiator Auto Registration
-
Do logic in intialize_connection() to do EMC-specific initiator registration.
- Storage Group Auto Deletion
-
Add resource recycling logic in intialize_connection()
- iSCSI Target Portal Selection
-
Add logic in intialize_connection() to select target portal that is pingable from the initiator.
- Multiple Authentication Type Support
-
Add new option in configuration file so that the driver can use different authentication types that have been supported by VNX arrays.
- Security File Support
-
Add a new option in configuration file so that encrypted credentials can be used instead of credentials in plain text.
- Storage-Assisted Retype
-
Implement driver API according to blueprint https://blueprints.launchpad.net/cinder/+spec/volume-retype.
- Storage-Assisted Volume Migration
-
Implement migrate_volume() so that VNX native LUN Migration is leveraged.
- SP Toggle for HA
-
Original implementation only send management requests to one SP. Since VNX arrays have dual SPs, the driver is enhanced to send requests to the other SP is one is down.
