[Bug 1959712] Re: [SRU] Add iSCSI support to HPE 3PAR driver for Primera 4.2 and higher

[Robie Basak]

Hello Corey, or anyone else affected,

Accepted cinder into focal-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/cinder/2:16.4.2-0ubuntu2 in a few
hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
focal to verification-done-focal. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-focal. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

** Changed in: cinder (Ubuntu Focal)
       Status: Triaged => Fix Committed

Bug description:
  [Description]
  OpenStack cinder in Focal (OpenStack Ussuri) is lacking iSCSI support for HPE Primera 4.2 and higher. This is now supported in Cinder and we would like to enable it in Ubuntu Focal as well as OpenStack Ussuri.

  The rationale for this SRU falls under harware enablement for Long
  Term Support releases.

  [Test Case]
  1. Deploy OpenStack with:
   - HPE 3PAR *iSCSI* driver enabled for Cinder
   - with Primera >= 4.2
    as per: https://docs.openstack.org/cinder/latest/configuration/block-storage/drivers/hpe-3par-driver.html
  2. Create a volume
    openstack volume create (--type hpe-primera) --size 10 sru-test-before

  3. Confirm the volume is successfully created while it gave an error
  as "For Primera, only FC is supported. iSCSI cannot be used"
  previously.

  [Regression Potential]
  This is a pretty simple patch. Where the code used to always raise a not implemented error for Primera, it now raises the not implemented error only for < Primera 4.2. Where things could go wrong? It's possible the version checking could have an issue but that code seems standard and the upstream patch has been merged back to stable/victoria [1]. Regression testing will cover that code path as well.
