Support additional volume group and snapshot features (info, rename, assign)

[lszomor]

SUMMARY

Hi Would it be possible to add additional features regarding volume groups and snapshots? I'd like to have support for the following features:

• Gathering volume group and snapshot information.
• Volume group rename capability
• An override flag to manage a mirrored volume

We are introducing FlashSystem arrays into our environment. We will depend on these features in our daily operations. I've implemented all the features for our internal use. Please find the links for them in the additional information section.

Thank you!

@lszomor svc_info module has been updated in 1.12.0 to support "Gathering volume group and snapshot information"

For 2) point above, will review the changes.

@Shilpi-J Thank you! I've merged the 1.12.0 release into our other features branches. Our playbooks updated to use version 1.12.0 and working as expected.

Thanks @lszomor For point 3) above "An override flag to manage a mirrored volume", we have a separate module ibm_svc_manage_mirrored_volume. Did you try this module to manage/configure mirrored volumes and face any issues ?

[lszomor]

Hi @Shilpi-J,

Sorry for the late reply. We are happily using the ibm_svc_manage_mirrored_volume to create HyperSwap volumes. I did not see an option to assign volume group (s) to it. Let me share our use case:

• We are creating a HyperSwap volume
• Then we create VolumeGroups for both sites
• After that, we assign the respective Hyperswap member volume to its designated VolumeGroup
• From the VolumeGroups, we create thin clones

@lszomor We have fixed this issue. The new code is available at: https://github.com/ansible-collections/ibm.storage_virtualize

Closing this issue. In case you face any other issue while using the feature, please raise it at: https://github.com/ansible-collections/ibm.storage_virtualize/issues

@Shilpi-J Thank you! I'll check in the upcoming days.
