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.

Apologies for the inadvertent closure.

Reproduced this issue with ssacli-3.30-14 + libstoragemgmt-1.7.3-3

[root@storageqe-65 ~]# lsmcli -u hpsa:// ld
PLUGIN_BUG(2): Got unexpected error 'NoneType' object has no attribute '__getitem__', please try to upgrade ssacli tool 
[root@storageqe-65 ~]# 
[root@storageqe-65 ~]# rpm -qa | grep ssacli
ssacli-3.30-14.0.x86_64

libstoragemgmt-python-clibs-1.7.3-3.el7.x86_64
libstoragemgmt-hpsa-plugin-1.7.3-3.el7.noarch
[root@storageqe-65 ~]# 


confirmed that after upgrad libstoragemgmt to 1.8.1-2.el7_9, this issue does not appear again,
the command "lsmcli -u hpsa:// ld" is successfully executed.
