Description Reid Wahl 2021-01-22 20:00:32 UTC
Consider for RHEL 7 since this is most likely verification-only.

+++ This bug was initially created as a clone of Bug #1919057 +++

Description of problem:

This is a request to support using fence_mpath and fence_scsi to manage SCSI persistent reservations on SPC-4-compliant devices. Both of these fence agents use the sg_persist command to manage reservations and keys. The `sg_persist(8)` man page suggests that it's compatible with SPC-4, so this probably only requires QA verification.

-----

Version-Release number of selected component (if applicable):

fence-agents-mpath-4.2.1-53.el8_3.1
fence-agents-scsi-4.2.1-53.el8_3.1

-----

How reproducible:

N/A

-----

Steps to Reproduce:

Test fence_mpath and fence_scsi fence agents managing SCSI persistent reservations on SPC-4-compliant devices.

-----

Expected results:

All tests pass -- that is, the agents behave the same with SPC-4 as with SPC-3 (currently supported).

Someone asked me about this today, and I realized I never opened the BZ.

Thoughts on cloning this for RHEL 7? Generally speaking, RFEs are a no-go. I ask because this is most likely verification-only.

You can clone it to RHEL7, and just add "Consider for RHEL7" to the top of the description.

This BZ is over a year old and hasn't had any activity from the reporter or any other non-bot account. If this feature backport is still desired, please follow the process to request an exception. If not, please close this BZ. Thanks.
