VMAX driver doc does not specify required licenses for cloning

[Carl Pecinovsky]

The mitaka driver info location is: http://docs.openstack.org/mitaka/config-reference/block-storage/drivers/emc-vmax-driver.html

There is a System Requirements section that lists some software components and levels; however, I believe the required VMAX electronic licenses need to be listed as well.

Driver was tried out on a VMAX-3. Got this failure:

ERROR.... Bad or unexpected response from the storage volume backend API: Error Create Cloned Volume: volume-myVM-4feee0fe-00000001-boot--5571521d-9bd5 Return code: 1. Error: The feature being requested is not currently licensed.

in: File "/usr/lib/python2.7/site-packages/cinder/volume/drivers/emc/emc_vmax_provision_v3.py", line 274, in create_element_replica

Please document what is needed. Thanks. From my read of EMC docs, it may be the following:

VMAX-2: SYMM_VMAX_TF_CLONE
VMAX-3: Local_Replication_Suite

The VMAX-3 in question already reports the following licenses:

Associator Name 0:
Symm_InventorySoftwareIdentity.InstanceID="SYMMETRIX-+-<array_id>-+-Advanced_Suite-+-5977_691_684"
Associator Name 1:
Symm_InventorySoftwareIdentity.InstanceID="SYMMETRIX-+-<array_id>-+-Remote_Replication_Suite-+-5977_691_684"
Associator Name 2:
Symm_InventorySoftwareIdentity.InstanceID="SYMMETRIX-+-<array_id>-+-VMAX_OS-+-5977_691_684"

Hi Helen,

Please note that this was previously being worked on by Kyle Laffoon as a training exercise.
Thank you for your patch, I see no current issues with it - please see my +2.

Please however contact the original assignee in future before taking the bug without notification.

Thanks,

Alex

Thanks Alex,
I would like the bug submitter to have a look over it before it gets merged. Would that be possible?

This was originally a 'finding' against Mitaka. Hopefully the backport there is coming?

This issue was fixed in the openstack/openstack-manuals 15.0.0 release.
