66.0. "SYSBOOT-W-ALOHUGEPAGE" by KERNEL::HORSNELL () Mon Mar 24 1997 07:19

    
    
    Hi,
    
    I've got a 4100 running 6.2-1H3 it's been up for just over 200 hours
    with very little activity. I thought it about time to run Autogen. This 
    was run from GETDATA - SETPARAMS, at a convenient time over the weekend
    it was then rebooted.
    
    It failed to BOOT with a SYSBOOT-W-ALOHUGEPAGE error and just kept
    looping. The system was then halted. I did a conversational boot and
    checked the GH_* params. I then set them back to the defaults. Rebooted
    and the system cam up ok.
    
    I checked the AGEN$PARAMS.REPORT file and noticed the following changes
    made by AUTOGEN
    
         GH_EXEC_CODE
           Feedback Information
             Old value was 512, New value is 1024
    
    
         GH_EXEC_DATA
           Feedback Information
             Old value was 128, New value is 112
    
        
         GH_RES_CODE
           Feedback Information
             Old value was 1024, New value is 1024
    
    
     Any ideas why Autogen resized GH_EXEC_CODE to a higher value and why
     did it cause the system to become unbootable.
    
     Many thanks
    
     Daryl.

    See note 118 in VMSNOTES_V12 for an explanation of the boot failure.
    
    Autogen will increase the GH_* values if there was an allocation
    failure from the GH regions during the bootstrap. It basically means
    that you've loaded more execlets than can fit in 512 pages. When there
    is no more room in the GH regions the execlets get loaded differently.
    So, the system will run fine, you just won't take advantage of the
    granularity hint stuff for those last few execlets.
