ibm_svc_info doesn't list any data reduction characteristics under the subset 'vol'

mainline-automation commented 1 year ago

SUMMARY

If you use ibm_svc_info to gather information on the vol subset you would expect to have all selectable attributes listed. However, I noticed today that it doesn't list whether the volume is thin or otherwise reduced.

ISSUE TYPE

Feature Idea

COMPONENT NAME

ibm_svc_info.py

ADDITIONAL INFORMATION

I'm trying to build a python module to get relevant data from provisioning volumes in order to update a csv file. While my input when creating a volume has thin provisioning, I found that I couldn't look at the volume-level data from the svc_info module to populate a volume that wasn't already in the csv file.

"Volume": [
    {
      "id": "24",
      "name": "xxxxxxxxxxx",
      "IO_group_id": "0",

    },

@mainline-automation, se_copy_count >=1 indicates that it is a thin provisioned volume. Also se_copy = yes indicated that volume copy is thin-provisioned and compressed_copy_count indicates number of compressed volume copies. Does that resolve your query? If yes, I'll go ahead and close this issue.

@mainline-automation, I am considering this resolves your query. If it doesn't, please feel free to reopen it and add additional queries about it.
