FAMS reason codes

Reason Code

Description

X'28xxnnnn'

nnnn is the specific FAMS reason code for this instance. All reason codes issued by FAMS are translated into a IGW01 message that is issued to the task. Convert the last two bytes (X'nnnn') of the reason code from hexadecimal to a decimal value and refer to that IGW01nnns message in z/OS MVS System Messages, Vol 8 (IEF-IGD), z/OS MVS System Messages, Vol 9 (IGF-IWM), and z/OS MVS System Messages, Vol 10 (IXC-IZP).

For messages with the prefix IGW01, the type codes indicate the severity of the detected error, as follows:

I Information:  Return code 0
W Warning:  Return code 4
E Error:  Return code 8
T Ending:  Return code 12
S Severe:  Return code 16

For example: Take the last 2 bytes of reason code RSN28260096. Converting X'0096' to decimal gives you 150. Prefixing it with IGW01 results in message IGW01150T.
