Re: HMC code update from the grave

Roberto,

Check to see if the firmware is HMC managed or not. If not, it should be. That is one of Larry's big landmines to step on. If the FSP firmware is OS managed, a set of PTFs could upgrade it and clobber your HMC connectivity without you planning and/or knowing about it. That could wind up with an unhappy series of events until the HMC is updated.

The fact that you were surprised about the firmware level leads me to wonder how that is set up.

In the end the hmc was at v6r1.3. I could swear the gui was not like
that in v6r1, but version 6 release 1.3 is what "about" tells me.
I'll just install the pre v7 efixes, check the asmi password and
proceed onwards to v7.
FSP was at 240_382, seems somebody other than me had already upgraded
the fw, maybe ibm back when it was under contract...
in any case, thanks all for the advice.

Best Regards,

Roberto
