marked as KPI to ensure it has both first and second threshold values
populated before the test runs.
- Removed trailing white space from performance metrics in the metric map.
System Changes
--------------
- SystemFunctions.get_audit_log_record() has been updated to extract audit log
record details after changes were made to Unisphere REST responses. What is
returned to the user from PyU4V will not change.
- set_director_port_online function added.
CI Test Improvements
--------------------
- Performance CI tests will output dead metrics to screen when encountered
instead of just failing and moving on.
- Array performance CI tests have been improved to provide better coverage of
all metrics and reporting of dead metrics.
- Certain tests are skipped if they are version specific and CI array does not
meet required version (V3/V4)
Building URI with args deprecated
---------------------------------
This functionality as provided by PyU4V.common.CommonFunctions._build_uri_args
has been marked for deprecation since PyU4V 9.1 and has been fully removed in
the 10.0 release. The impact of this is such that the following methods must
be called with kwargs to form target URIs if you are using them for access
to custom REST endpoints.
- PyU4V.common.CommonFunctions.get_resource
- PyU4V.common.CommonFunctions.create_resource
- PyU4V.common.CommonFunctions.modify_resource
- PyU4V.common.CommonFunctions.delete_resource
Deprecated functions to be removed in 10.2
------------------------------------------
These functions will been removed entirely from the PyU4V code-base after the
required two release notification period.
- Old: PyU4V.provisioning.ProvisioningFunctions.create_multiport_port_group
- New: PyU4V.provisioning.ProvisioningFunctions.create_new_port_group
- Old: PyU4V.provisioning.ProvisioningFunctions.create_port_group
- New: PyU4V.provisioning.ProvisioningFunctions.create_new_port_group

Version 9.1.5.0 - released 21/09/20
===================================
Bug fixes
---------
- Fixed a bug in performance CI tests where tests would fail if there was no
provisioned assets in certain performance categories. The tests will skip now
instead of failing.
Version 9.1.4.0 - released 09/09/20
===================================
Bug Fixes
---------
- GitHub Issue #93 (https://github.com/dell/PyU4V/issues/93) has been resolved.
Users can now create storage groups with volumes in the same request where no
service level has been specified as an input parmaeter or service level is
set to None. In addition, another bug found whilst fixing #93 whereby storage
groups with no service level set were created with no storage resource pool
regardless of user input parameter value.
- GitHub Issue #92 (https://github.com/dell/PyU4V/issues/92) has been resolved.
User documentation has been updated to correct the error in the path to
set a custom PyU4V.conf location.
Version Control
---------------
- Pep8 test suite flake8 package version has been upgraded to 3.8.3
- Pylint test suite package version has been upgraded to 2.5.3
Quality Control
---------------
- The change to Pylint version resulted in more stringent code analysis, as
such a number of changes were made in the following files to bring the code
rating back up to 10.0/10.0:
- PyU4V/common.py
- PyU4V/performance.py
- PyU4V/provisioning.py

Version 9.1.2.0 - released 19/12/19
===================================
Provisioning Enhancements
-------------------------
- add_new_volume_to_storage_group : added functionality to be able to add
volumes to SRDF protected storage groups, new volumes will automatically be
protected with SRDF, volumes are added to the remote storage group to fully
automate the provisioning and simplify operations. Storage group must be
local to the unisphere instance and only works with storage groups that
contain R1 or R11 devices.
- remove_volume_from_storage_group enhanced to be able to automatically remove
volumes from local and remote storage groups deleting srdf pairs as part of
the process, no need to suspend, the automation takes care of everything,
storage group must be local to the unisphere instance and only works with
storage groups that contain R1 or R11 devices.

by PyU4V.
- If the user does not supply environment settings or they cannot be loaded
from the config file an exception is raised during initialisation of
U4VConn()

around except for the rest_client
- List/Dict comprehension have been cleaned up
- Decorators have been created for deprecating/refactoring methods, see section
'Refactoring & Deprecation' below

and rotate through 10 of them with the most recent always being PyU4V.log
- Separate handling of SSLError, Timeout, HTTPError, and ConnectionError REST
exceptions, allows for more granularity when diagnosing problems
- PyU4V will run a Unisphere validation check in U4VConn() __init__, if the

- Functions now expect integer numbers instead of string representations of
numbers expected by the Unisphere REST API, the intention is to make the use
of PyU4V as simple as possible and let us take care of casting required types
- Online Device Expansion is included presenting users with the ability to
extend R2 devices in the same operation as extending R1 devices.
Provisioning Enhancements
-------------------------
- get_available_initiator_wwn_as_list() : Get a list of available initiator
WWNs
- get_in_use_initiator() : Get an initiator that is in use filterable by
director type
- get_available_initiator() : Get an available initiator filterable by director
type
- get_fa_directors() : Get all FA directors on the array.
- get_active_masking_view_connections() : Get list of active connections from
any masking view
- format_director_port : Format separate director port into single string
- get_any_director_port : Get a non-GuestOS port from a director
Fixes
-----
- When searching for volumes by volume name, if more than one volume matches
the input volume name a list of volume device IDs will be returned, if only
one volume is matched just that device ID is returned as a string
- Fix for establishing a session when none exists during rest requests
- PyU4V.conf loading on Windows from user home directory now working as
intended from default location of ~/.PyU4V
- Removed CFG from header of univmax_conn.py and set it in __init__ so users
file_path is now read as intended
- Removed CFG from header of utils files, it was unnecessary to have it
included there, it only needs set once in U4VConn()
- The function migration.get_storage_group_list() set includeMigrations to
False incorrectly returns all SGs in the migratingNames list, a new function
migration.get_storage_groups() has been added which returns the default
response of a dict containing all SG names and those SGs which are part of a
migration session
- The function migration.delete_environment() was deleted as it is a duplicate
of function migration.delete_migration_environment()
- CSV writer has been changed to use correct file writing modes and practices
- Pull #30 Modify initiator reverses alias name during a rename operation
- Pull #34 Get target wwn fails to split director:port return value
- Pull #38 Incorrect type in docstring of get_size_of_device_on_array
- Split returned port ids correctly during port group create/modify operations.
Tests
-----
- 100% unit test coverage with all tests running cleanly across both unit and
CI
- All suitable functions now have a respective Continuous Integration (CI) test
- Extensive CI test coverage
- Requests session establish is tested instead of mocking behaviour
- Fake request session mock has been changed so it does not adversely affect
other tests when full suite of tests is run
Refactoring & Deprecations
--------------------------
The following methods have either been refactored and marked for deprecation
after PyU4V 9.3 or just marked for deprecation with no refactoring. To reduce
the impact on end-users which may use these methods in their scripts an n+2
deprecation policy has been adopted.
For any methods marked for deprecation in the current release, they will need
to remain in PyU4V for two full releases before being completely removed. As
this policy has only just been implemented for PyU4V 9.1, all methods below
marked for deprecation after PyU4V 9.3 will be removed entirely in PyU4V 9.4 or
whatever the equivalent version is for n+2.
It is assumed that after two full releases users will have had enough time and
notice to make the required changes in their code. Any methods which have been
refactored in favour of other methods will be clearly marked in the associated
logs generated when a refactored function is in use.
