If your doing maintenance and want to start into a restricted state, just change the IPL attributes to start that way. (You have to change it each and every time you IPL when you want restricted state) That way you don't mess with the start up program system value.

Also the HMC does not rely on any of those processes running so and HMC console should not have issues. Aside from some small issues with connectivity to the FSP the HMC is nearly as reliable as the twinax console was (I did say /nearly/ before the howls start) While LAN console can be a bit more temperamental ordinarily it's quite reliable as well.

I used to do this by habit in order to control everything via the
QSTRUPPGM but am currently re-thinking this approach.

My old approach has an inbuilt assumption that there will be access
available that does not rely on TCP, but I have been caught a couple
of times where this assumption has been faulty and QSTRUPPGM has been
changed to *NONE - thereby making access to the system problematic
where there is a console issue.

I often change QTSRUPPGM to *NONE when doing maintenance and this can
cause access issues if the console is compromised.
