NOF Indications
DLUR_PU_INDICATION
One or more previous directory indications were lost. Later fields in this VCB may be set to zeros.
AP_NO
No previous directory indications were lost.
reason
Reason for this indication. Possible values are:
AP_ADDED
The DLUR has just been activated by the DLUS.
AP_REMOVED
The DLUR has been deactivated, either explicitly by the DLUS or implicitly by a link failure or the
deactivation of the PU.
lu_name
Name of the logical unit (LU). This is an 8-byte alphanumeric type-A EBCDIC string (starting with a letter),
padded on the right with EBCDIC spaces.
pu_name
Name of the physical unit (PU) that this LU uses. This is an 8-byte alphanumeric type-A EBCDIC string
(starting with a letter), padded on the right with EBCDIC spaces.
nau_address
Network accessible unit (NAU) address of the LU. This value must be in the range 1–255.
4.5 DLUR_PU_INDICATION
This indication is generated when a physical unit (PU) for the node that supports the dependent LU requester
(DLUR) function is attempting to activate, fails to activate, activates, or is deactivated. This indication can be used
to maintain a list of currently active DLUR PUs.
