I want the ability to designate a specific LPAR to be the Master in a Basic HyperSwap environment via a parmlib member. Right now, I just go to the LPAR which I would like to be the Master and then just issue a ro *other,p hsib and wait for the *IOSHM0803E HyperSwap Disabled and the IOSHM0807I HyperSwap Management Address Space ready messages to come up on that LPAR before issuing the s hsib,sub=mstr command on the other LPARs. So, let's say that I have the Master LPAR that I got from performing the manual procedures listed earlier and that Master LPAR gets IPLed for some reason. Well, right now what happens is that Master designation goes to a different active LPAR automatically and that is fine. What I want to happen is that when the LPAR comes back up is to take over the z/OS Basic HyperSwap Master designation automatically without me having to do anything. Please refer to the following ticket that I opened:
TS015859540
Is there a way in z/OS 2.5 RSU2401 with a z/OS Basic HyperSwap configuration where you could force or hard assign a specific LPAR in the SYSPLEX as the z/OS HyperSwap Master LPAR? The way I am doing it now is manually. That is, after all six of my LPARs are shut down and IPLed on the weekends, at different times too, I shut down all the HSIB Address spaces from the LPAR that I want to be the Master by issuing, ro *other, p hsib. I am using z/OS HyperSwap, at this moment in time, as a Proxy to connect to the DS8950F HMC's embedded CSM 6.3.7.0 Servers. Once the HISB servers are stopped on all the other z/OS LPARs in the SYSPLEX and I get the following message on the Master z/OS LPAR's console: *IOSHM0803E HyperSwap Disabled
IOSHM0807I HyperSwap Management Address Space ready
I then would Start HSIB,sub=mstr and each of the other SYSPLEX LPARs. I have no configuration set for z/OS HyperSwap Address Spaces as I am not using it for a Hardened Freeze or HyperSwap. I was just wondering if there was a way I could force the z/OS HyperSwap Master designation automatically to a specific LPAR when the IPL gets IPLed or whenever the HyperSwap Address Spaces start-up. I will display the way they are now on my LPARs. The Master jumps from LPAR to LPAR when the LPARS are re-IPLed on the weekend and they get IPLed at different times. We don't shut all of them down at one time and then bring one at a time up. They get shutdown and IPLed at different times so there is always something up. Thank you. The Hyperswap display commands:
