Applies Only to Purity version 6.4.4 and 6.4.5

Arrays running versions 6.4.4 and 6.4.5 are impacted by bug PURE-296865 - Fix pyjwt string encode issue in EUC phonehome which will not properly generate and phone home the utility_billing.json file.

Cause

This issue is caused by a problem in the utility_billing.json generation script called space_utility_json.py

Do NOT upgrade space_utility_json.py on arrays running 6.4.3 or earlier, the fixed version of the script is not backwards compatible.

Resolution

In order to remedy this problem the space_utility_json.py script can be upgraded manually on impacted arrays.

The recovery procedure is as follows:

1. The fixed version of the script i.e. space_utility_json.py can be found here: /shared_folders/lkarnavat

2. The fixed script must be transferred to both controllers of the impacted arrays using: vats push space_utility_json.py <array_name>

3. Finally the existing script should be replaced with the fixed version. The path for the live script on FlashArray is

/opt/Purity/bin/space_utility_json.py

4. Then the script can be replaced on both controllers via:

cp ./space_utility_json.py /opt/Purity/bin/space_utility_json.py

5. The script can be optionally, manually tested for verification by running: 

cat /opt/Purity/bin/space_utility_json.py

Output should look something like:
