Re: The name of a volume created via cinder doesn't match the name in the array (ESeries E5524)

JULIANDIAZ · ‎2014-09-05

When a volume is created in openstack (cinder icehouse) using: "cinder create" the name of the volume in the storage array doesn't match the ID of the volume assigned by cinder. Here is an example:

From Openstack's point of view:

# cinder list | grep test-netapp

+----------------------------------------------------------+------------+----------------------+-------+--------------------------------------+------------------------------------------------------------+

+----------------------------------------------------------+------------+----------------------+-------+--------------------------------------+------------------------------------------------------------+

From Netapp e5524's point of view:

Name	Id	TotalSizeInBytes	Wwn
S32MMULVYBCMXMB6PZHQ7NBN64	0200000060080E5000297EA400000B8B5406D9F4	268435456000	60080E5000297EA400000B8B5406D9F4

As you can see the same volume has a completely different name in both platforms which makes it very difficult for us to match a volume both ways. We have other netapp arrays and we don't have this issue.

Thanks in advance

Hi Julian

Yes - this is a known issue with the E-Series driver. The problem stems from the fact that Santricity cannot hold the uuid as a volume name so a conversion is done from the cinder uuid to a format that Santricity can use/display. We have created a bug here https://bugs.launchpad.net/cinder/+bug/1366060 to track this issue. We hope to be able to give you the information through something like this:

cinder show <volume-id>

…

ext:netapp-eseries-label {u’label’: u’S32MMULVYBCMXMB6PZHQ7NBN64’}

Thanks
