ABSTRACT: PSF/AIX Direct: 3900 printer drains when we get paper jam
SEARCH ARG: psf/aix jam
TOPIC THREAD: PRINT
PSF/AIX
..
My customer is experiencing a problem with 3900 narrow duplex printers
attached to PSF Direct under PSF/AIX. When the 3900 gets a paper jam,
the SDSF console shows INT REQ for the printer instead of DRAINING or
STARTING. The PSFSTAT command shows INTERVENTION for the printer. On
the RS/6000 we get a message that says:
0420-466 The printer reported a paper jam; clear the jam.
followed by:
message from printer prt25
0420-469 The printer transport mechanism requires corrective
action.
followed by:
0105-2735 Session DYNAMIC {59} LS:prt24pf DALSWB00.PRT0025 /
DALSWB00.PSF6025/ has become inactive.
The jam is cleared and the paper web reattached. Now the operator
does a thread to align on the printer and when it completes, the
job hops off the printer. The printer goes drained to JES2 and
IDLE to PSF/AIX.
Is this the way it's supposed to work? It does not work this way
for other interventions such as out of toner. Thanks for the help.
Q:
One question we need to ask is where is the jam occurring? Does the
customer have any pre- or post-processing equipment? Knowing more
about the customer's configuration would help. At any rate, one thing
to check would be that the operators are following the correct
operational procedures for clearing the paper jam.
Another question we need to ask the customer is what value is set for
Device INTERVENTION timer (under PSF/AIX TUNING options). If he has
the device intervention timer set to something other than 9999, then
when they get a paper jam, the host will eventually be notified of
a "permanent" condition and the MVS writer will go down.
Next, please have the customer check their PSF/MVS startup PROC to see
what their FAILURE parameter is set to (described on pg. 39 in PSF
Direct manual). If they have:
FAILURE=STOP - that means PSF/MVS must be restarted by the
operator after a printer or communication failure.
FAILURE=WCONNECT - that means PSF/MVS will attempt to communicate
again with PSF Direct if there has been either
a printer or communication failure.
If there is no FAILURE parameter set in their writer proc, it defaults
to WCONNECT.
When the tester tried a paper jam in the lab, she was running on AIX
AIX 3.2.5, SNA Server/6000 1.3, PSF/AIX 2.1.0 with the latest PTF
(PTF# U441774). The PSF/AIX device intervention timer was set at 999
and the PSF/MVS startup proc had FAILURE=WCONNECT (more details below).
She was notified at the AIX system that there was a paper jam and got
the "inactive" message:
0105-2735 Session DYNAMIC {xx} LS:xxxxxxx USIBMBQ.PSFDDENB /
USIBMBQ.PSFFSA2/ has become inactive.
The psfstat command showed "intervention" just like the customer's.
When she cleared the paper jam, the printer recovered and continued
printing. She checked the status of the 3900 on MVS during and after
the paper jam, and both times the status was ACTIVE.
There is a good explanation of intervention conditions on pg. 228
of the PSF Direct Network Configuration Guide (S544-5287-01). You
might look at that or have the customer take a look at that. It
describes the differences between attaching a channel printer directly
to a S/390 host and attaching a channel printer through PSF Direct;
a PSF Direct-attached printer behaves as an SNA-attached printer, so
there are some operational differences.
If the customer's device intervention timer is set to 9999, if they have
FAILURE=WCONNECT in their PSF/MVS startup procedure, and if they are
following the correct operational procedures as described in the Network
Configuration Guide, then they should open a PMR with the Support
Center. We will ask for some SNA and/or PSF Direct traces, and will need
to know what level of PSF/MVS they are running. We can also get the
PSF/MVS folks involved if it doesn't look like a PSF Direct problem.
In the meantime, the tester will also try this scenario on an AIX V4
system since that is what your customer is running.
I hope that helps--let us know. Thanks for using ASKQ.
