OS release OS400 2 7 00100004604T is not supported with this kernel (741)

We were in AS/400 V7R1 and have recently upgraded to V7R2. According to PAM, our Kernel 7.41 should still work for V7R2. Why then are we receiving this error when logged into the system: "OS release OS400 2 7 00100004604T is not supported with this kernel (741)".

We are currently in 7.41 Non-Unicode 64 bit.

    Hi Cristina,

    trace file dev_rd indicates a signal 6 in sapgenuuid(). With that, I've found SAP Note 2288677, which suggests to install the latest patch for SAP Host Agent (current patch level for release 7.21 is 31) as it provides API sapgenuuid for kernel releases 7.42 and higher.

    Kind regards,

    Christian Bartels.

    Hi Cristina,

    I added a couple tags to your question to help increase visibility. As this is an operating system question at its core, adding a tag for your OS (or DB platform) would be best. I added "IBM z/OS," but I'm not an expert with IBM systems, so it may be that a different tag is more appropriate.

    You are correct in that the PAM says that for OS/400 V7R2 the Kernel 7.41 Non-Unicode should still work. However, kernel 7.41 has been out of maintenance for a couple years now. You should seriously consider updating to kernel 7.49, or at least 7.45. The PAM indicates that 7.49 remains downward-compatible with V7R2, so that shouldn't be an issue.

    I would also draw your attention to Note 1969546 (Release Roadmap for Kernel 74x and 75x), which draws out minimum kernel releases based upon your NetWeaver Support Pack level. For instance, if you are running NetWeaver 7.4 and have Basis SP 8 or higher, you must be on at least kernel 7.42.

    It would also help if you could let everyone know what your NetWeaver release is (I assumed for the moment that you're on 7.4), and your Support Package Stack level (or at least, SAP_BASIS sp level, assuming this is an ABAP system).

    Cheers,
    Matt

      Thanks for this FYI, Matt. SAP Host Agent Upgrade resolved our startup issue. However, we encountered CONVT_OVERFLOW upon execution of ST06 after the OS Upgrade to V7R2. May we know if you have any idea how to resolve this? We are on SAP Netweaver 7.4 SAP_BASIS SP Level 6.

    Thanks, All. We found SAP Note 2537239 also and proceeded in upgrading SAP Host Agent which resolves the issue in startup. Right now, we are experiencing CONVT_OVERFLOW dump upon execution of ST06 after the said Kernel Upgrade as seen on the attached file. May we know how can this be resolved?

    • This sounds like the problem that is described in SAP Note 2338102 - ST06: Runtime error CONVT_OVERFLOW when calling transaction. The solution was provided in SAP NetWeaver 7.40 SP16, but there are also correction instructions available that are attached to the SAP Note.

      Kind regards,

      Christian Bartels.

    Hi Cristina,

    Based on the error in dev_rd regarding signal 6 , please see note #2537239 - IBM i : Signal 6 encountered: sapgenuuid()

    to resolve the issue.

    The entries in the dev_rd can be seen as:

    Signal 6 encountered.
    => 64 bit R/3 Kernel
    => 64 bit OS400 Kernel
    
    sapgenuuid() at 0x1000de54c
    	pfget_uuid() at 0x10064f698
    	pfcreate_sap_uuid_force() at 0x10064f13c
    	GwInitReader__FiPPc() at 0x1000022c0
