RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description John Pittman 2020-08-26 14:33:10 UTC 
Description of problem:

[root@hostname ~]# lsmcli -u hpsa:// ld
PLUGIN_BUG(2): Got unexpected error 'NoneType' object has no attribute '__getitem__', please try to upgrade ssacli tool

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

RHEL 7.8 using ESKM encrypted storage

How reproducible:

Every time

Steps to Reproduce (from end customer):

To recreate the problematic text that we're excluding in the plugin just run:

   ssacli ctrl all show config detail

And on ESKM encrypted controllers you'll see:

Encryption is enabled on this controller. Data stored on physical drives
exposed to the OS and not configured in an Array are not encrypted.

If you don't exclude these the plugin fails for certain options.

Additional info:

Workaround (from end customer) from /usr/lib/python2.7/site-packages/lsm/plugin/hpsa/hpsa.py

change:

            elif output_lines[i].startswith('Note'):
                # Discard
                pass
            else:
                sanitized.append(output_lines[i])

to

            elif output_lines[i].startswith('Note') or output_lines[i].startswith('Encryption is enabled') or output_lines[i].startswith('exposed to the OS'):
                # Discard
                pass
            else:
                sanitized.append(output_lines[i])
Comment 6 Chris Williams 2020-11-11 21:55:56 UTC 
Red Hat Enterprise Linux 7 shipped it's final minor release on September 29th, 2020. 7.9 was the last minor releases scheduled for RHEL 7.
From intial triage it does not appear the remaining Bugzillas meet the inclusion criteria for Maintenance Phase 2 and will now be closed. 

From the RHEL life cycle page:
https://access.redhat.com/support/policy/updates/errata#Maintenance_Support_2_Phase
"During Maintenance Support 2 Phase for Red Hat Enterprise Linux version 7,Red Hat defined Critical and Important impact Security Advisories (RHSAs) and selected (at Red Hat discretion) Urgent Priority Bug Fix Advisories (RHBAs) may be released as they become available."

If this BZ was closed in error and meets the above criteria please re-open it flag for 7.9.z, provide suitable business and technical justifications, and follow the process for Accelerated Fixes:
https://source.redhat.com/groups/public/pnt-cxno/pnt_customer_experience_and_operations_wiki/support_delivery_accelerated_fix_release_handbook  

Feature Requests can re-opened and moved to RHEL 8 if the desired functionality is not already present in the product. 

Please reach out to the applicable Product Experience Engineer[0] if you have any questions or concerns.

the command "lsmcli -u hpsa:// ld" is successfully executed.
