VDS_E_ASSOCIATED_PORTALS_EXIST
This HRESULT is a portal-group lifecycle guard. VDS exposes a portal group as a configuration object associated with one or more iSCSI portals. IVdsIscsiPortalGroup::Delete requires those portal associations to be removed first; the group is not just a label that can be deleted while endpoints remain attached.
Why this state matters
The error is therefore different from an unreachable portal. A portal can be offline or inaccessible and still remain associated with the group in the provider configuration. Network testing does not remove that relationship. The provider topology must be changed explicitly, then the portal group can be deleted.
Diagnostic focus
- Enumerate the portals associated with the portal group and capture their VDS object IDs and IP/port properties.
- Remove portal associations through the provider API instead of deleting DNS records or disabling NICs as a substitute.
- Wait for portal-removal asynchronous operations and refresh the provider view before retrying group deletion.
- Check that another management process is not re-adding portals through array configuration or automation.
