VDS_E_INVALID_ISCSI_PATH

This is the iSCSI-specific structural path error. For an iSCSI path, VDS_PATH_INFO uses a target portal ID, an initiator adapter ID, and a pointer to VDS_IPADDRESS for the initiator portal address. The published HRESULT definition identifies either an incorrect path type or a null initiator-portal properties pointer.

Why this state matters

The code is therefore more precise than a failed iSCSI login. VDS is rejecting provider-supplied path metadata before the path can be treated as a valid endpoint description. A target can still be logged in through another session or portal while one provider-returned path object is malformed.

Diagnostic focus

  • Preserve the path ID, type, target portal ID, initiator adapter ID, and whether the initiator portal address pointer is null.
  • Compare the malformed path with working iSCSI paths to the same LUN and provider.
  • Check provider cache synchronization and reenumerate the hardware/provider object graph before retrying path-policy operations.
  • Use initiator session diagnostics only after validating the path structure; login retries do not repair a null VDS path field.
