Use this command to deactivate a network addressable unit (NAU) and all its
subordinate NAUs.
Requirements and Restrictions
The TPF system must be in CRAS state or higher.
Format
- Id
- specifies the NAU to be deactivated, which can be one of the
following:
- netid.nau
- deactivates the specified NAU, where netid.nau is 1- to
17-character symbolic NAU name. The network ID and name of a
resource must both begin with a letter (A-Z), @, #, or
$. The remaining characters can be letters (A-Z),
numbers (0-9), @, #, or $.
- Note:
- To specify an SNA network ID or resource name that contains dollar signs
($), you must type two consecutive dollar signs ($$) for
each dollar sign in the network ID or resource name. For example, if
the SNA resource name is $SNANAME, you must type
$$SNANAME.
- CTCNODES
- deactivates all active channel-to-channel (CTC) links.
- ALSNODES
- deactivates all PU 2.1 links.
- Note:
- If you specify the ALSNODES option for the ID parameter, you cannot activate
any PU 2.1 links on this processor until you enter ZNETW ACT
ID-ALSNODES to allow PU 2.1 link activation again.
- CPCP
- deactivates the APPN CP-CP sessions.
- Note:
- You must specify the FORCE parameter if you enter this command from a TPF
processor in the loosely coupled complex that does not own the CP-CP
sessions.
- Immediate
- immediately deactivates the specified NAU.
- Force
- forces the deactivation of the specified NAU.
- SAVEsess
- performs a nondisruptive cross-domain resource manager (CDRM)
deactivation; that is, no LU-LU sessions are ended.
Additional Information
- Online help information is available for this command. To display
the help information, enter one of the following:
ZNETW HELP
ZNETW ?
- If you do not specify the IMMEDIATE or FORCE parameter, a normal shutdown
is performed.
- If you deactivate a local or remote LU, all sessions with that LU are
ended.
- If you deactivate a local primary LU (PLU) that has secondary LU (SLU)
threads, all sessions with the SLU threads (except TPF/APPC SLU thread
sessions) are ended.
- If the local PLU is a TPF/APPC LU with SLU threads, you must deactivate
each SLU thread separately.
- When you perform a nondisruptive deactivation on a CDRM session where the
system services control point (SSCP) supports DACTCDRM type 4, all associated
LU-LU sessions are disassociated from their controlling CDRM session.
Both SSCPs do not remember the earlier relationship between the LU-LU sessions
and the nondisruptively deactivated CDRM session when the CDRM session is
restarted.
- If the TPF processor that owns the CP-CP sessions is deactivated, you can
enter ZNETW INACT ID-CPCP,FORCE from another TPF processor in the
loosely coupled complex. This command clears the processor shared value
that indicates which processor owns the CP-CP sessions; however, it does
not end the CP-CP sessions. Therefore, if the network still
thinks the CP-CP sessions are active, you must deactivate the CP-CP sessions
from the operator console of the remote CP. After the CP-CP sessions
with the deactivated TPF processor have ended, new CP-CP sessions can be
established with a different TPF processor in the loosely coupled
complex.
Examples
A NAU is deactivated in the following example.
+--------------------------------------------------------------------------------+
|User: ZNETW INACT ID-RCS1 |

|System: NETW0011I 08.47.21 APPL RCS1 INACT PROCESSING BEGUN |
| NETW0033I 08.47.28 APPL RCS1 INACT PROCESSING COMPLETE |
+--------------------------------------------------------------------------------+
An NAU is forcibly deactivated in the following example.
+--------------------------------------------------------------------------------+
|User: ZNETW INACT ID-RBS1B001,F |

|System: NETW0011I 08.46.56 LU RBS1B001 INACT,F PROCESSING BEGUN |
