Notes

Note

  • Parameters mdm_name or mdm_id are mandatory for rename and modify virtual IP interfaces.

  • Parameters mdm_name or mdm_id are not required while modifying performance profile.

  • For change MDM cluster ownership operation, only changed as true will be returned and for idempotency case MDM cluster details will be returned.

  • Reinstall all SDC after changing ownership to some newly added MDM.

  • To add manager standby MDM, MDM package must be installed with manager role.

  • The check_mode is supported.

  • The modules present in the collection named as ‘dellemc.powerflex’ are built to support the Dell PowerFlex storage platform.
