Add a parameter to control the time allowed between IPLs in different CPCs (message ILR031A)

Hello,
 

(We use z/OS 2.5 and GDPS 4.6)


We use GDPS to perform DR scenarios.

In our DR scenario testing, we've mastered the process and can now perform the whole process in less than 20 minutes. 

We currently DR the Production systems in 21-22 minutes and plan to go below 20 as well soon.

When we IPL the LPARs on the other CPC, we get the following messages:
ILR030A
ILR031A

According to the documentation, this message might appear when a new CPC is detected and the last CPC used the protected datasets less than 20 minutes ago.

We bypassed this problem by adding the ILR031A reply to the Auto Reply mechanism (member AUTORxx in the PARMLIB).

To avoid this false error entirely, I suggest adding a parameter to IECIOSxx (or any other member in the PARMLIB you deem appropriate) to control the time allowed between IPLs in difference CPCs.

I understand the need for this protective mechanism, however, adding a user controlled parameter will enable the user to decide the "intensity" of this protection.  The user will be able to make a knowledgeable decision and avoid what he/she regards as a false error.

Thanks in advance

    .IBM does not see a strong business justification case for implementing the request.
