Dell - Internal Use - Confidential

We had to skip these tests in our CI as well. Our EqualLogic array's IQNs are too long as well.

Subject: [Bug 1432490] Re: TestEncryptedCinderVolumes cryptsetup name is too long

For what it's worth, HP Lefthand Volume IQN's are just as long as
Datera's. Cinder/Openstack cannot enforce length restriction on iSCSI
array vendor's IQN length.

Title:
  TestEncryptedCinderVolumes cryptsetup name is too long

Status in Cinder:
  Invalid
Status in OpenStack Compute (Nova):
  Invalid
Status in Tempest:
  Invalid

Bug description:
  First off, while I understand this is not reproducible with the
  reference implementation LVM, this seems like a unknown limitation
  today since we're not enforcing any length on the IQN or recommending
  anything.

  When running Datera storage with Cinder and the following
  TestEncryptedCinderVolumes tests:

  {0} tempest.scenario.test_encrypted_cinder_volumes.TestEncryptedCinderVolumes.test_encrypted_cinder_volumes_cryptsetup
  {0} tempest.scenario.test_encrypted_cinder_volumes.TestEncryptedCinderVolumes.test_encrypted_cinder_volumes_luks

  cryptsetup complains about the name being too long:

  http://paste.openstack.org/show/192537

  Nova uses the device name that's in /dev/disk-by-path, which in this
  case is the returned iqn from the backend:

  ip-172.30.128.2:3260-iscsi-iqn.2013-05.com.daterainc:OpenStack-
  TestEncryptedCinderVolumes-676292884:01:sn:aef6a6f1cd84768f-lun-0

  Already started talking Matt Treinish about this on IRC last week.
  Unsure where the fix should actual go into.
