APAR status

  • Closed as program error.

Error description

  • The sysdumpdev -e may show invalid values, mostly very
    high number which can lead to the 'DMPCHK_TOOSMALL'
    errpt entry.
    

Local fix

  • N/A
    

Problem summary

  • trying to force a system dump from command line will fail
    if the y4 adapter is configured in the system.
    The failure happens because  the y4 reports an incredible
    large dump size.
    

Problem conclusion

  • The value of the size is passed from the device driver
    by returning a pointer to the location of the value.
    The caller is expecting the value to be stored in a 64 bit
    value. The device driver was saving the value in a 32 bit
    location, forcing the caller to interpret the value as a
    huge size number.
    The solution is to store the value in a 64 bit variable.
    

Temporary fix
