    Initial Program Load (IPL) failed. The channel program failed to complete within the maximum allowable time, or, completed with bad status causing the load operation to fail.Verify that the control unit or device is operating properly. Try the load operation again. If the problem continues, select Service

    Hi, could you provide the PSW which you can get from Hardware messages at HMC

    Hi Joao,

    I am wondering if you had found a solution to this as I am dealing with the same issue on a Z14. This error does not give a PSW or wait state code. It just gives plain text

    Problem Description: Initial Program Load (IPL) failed. The channel program failed to complete within the maximum allowable time, or, completed with bad status causing the load operation to fail. 

    Corrective Actions: Verify that the control unit or device is operating properly. Try the load operation again. If the problem continues, select Service. 

    Impact of Repair: The repair of this problem can most likely be performed concurrent with system operations.

    Hello 

    Please check your I/O configuration. Is your IPL device reachable by these LPAR? Are all channels online on these LPAR?

    Regards

    Hello Daniel,

    the configuration did not change and it worked normally.
    This happened following a power outage, the BAY ds8870 and the Z114 were all affected

    Hi,

    did you open a case for that problem? Without more details, it's hard to diagnose. Check, whether there are any hardware messages for your z14. Maybe some adapters are not working anymore.

    Otherwise, try answering some general questions, to isolate the problem:
    Is it only one partition that no longer IPLs or are multiple LPARs affected?

    If multiple LPARs, are they all belonging to the same SYSPLEX?
    I just one, what is different for the failing LPAR compared to other LPARs that are still IPLing?

    HI Grötzner
    In fact you know the Z114 is EOL and EOS. There are 2 Z/OS LPARS and 3 ZLINUX LPARs but for all it is the same message .

    Maybe I'll review the adapters
    to attack the storage we use the CHPID 221 which is operational.

    Can't it be at the Storage level?

    Hi Mamadou,

    if the problem affects all LPARs and different types of LPARs, then yes. It is more likely that something in the path from your z114 to the storage server is not working. Assuming that you did not change the I/O configuration that was working before, I would investigate into the infrastructure/cabling between the z114 and the storage server first. Are all cables still plugged? Maybe, cleaning the plugs already helps.
    Is the storage server directly attached or via a switch? The switch might tell you whether the communication to the Z server or to the storage server has any problem.

    Hi Michael,

    THE z114 Is connected directly with the DS8870.
    I will review the cabling.

    In fact, I suspect the ds8870 a little, because it seems to be running well, but I can't access the DS STORAGE MANAGER

    Hi Mamadou

    You wrote that you had a power loss. Did you selected the correct IOCDS (A0 to A3) during por activation? Maybe there is one IOCDS selected which do not specifiy your dasd devices. 

    Regards

    Daniel

    Hi Daniel
    I think liocds A0 is good and it's the one that has always worked

    Hi Mamaduo

    You can check the connection to the devcie via HMC. Select your z114 and go to "Single Object Operations". From there select channels and then your pchid 221. The select "Channel Problem Determination" under "Channel Operations".

    Now you can select your LPAR and press the "ok" button. Now I recommend to select "Analyze control unit header..." and press again OK. Take "Search by device number..." and press again OK. Now you can enter your IPL device nummer and press OK.

    You should see a report about the device, the paths to the device, the serial number of the DS8870 etc.  I attach a sample of the output. 

    If you dont see the correct information you have a configuration problem or a hardware defect. You can try an other channel if avaiable. 

    Regards Daniel 

    Btw, I can't see your pictures attachement.

    HI MICHAEL


    I just redo all the checks. But apparently the Z114 sees the DS8870 well

    Hi Mamadou

    I cann't see your attached pictures.  Can you attach it via web interface?

    Is hard to guess what you see.

    Hi Daniel,

    We say perhaps the volumes are soft fenced state.
