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
