Re: HMC code update from the grave

One way to ensure you know the HMC password is to go into the ASMI from the HMC and change it BEFORE you do anything else. That has saved my backside a time or two since customers rarely know what the CE or installer set it to in the first place. Then if they think they know, it's almost always not correct. Customers with legislative constraints, or that have a full time administration staff usually know the password and it's correct.

Two things to keep in mind:

1) Watch for the relationship between the firmware and HMC. That is,
don't update the HMC too far all at once so that you loose connection to
the FSP.

-and more importantly-

2) Make sure you have the HMC access password. If you completely reload
the HMC then it will 're-introduce itself' to the FSP and the FSP will
require that password. (Yes you can reset the FSP with the magical
switches but then it kinda forgets everything it knows.)

He reloaded the one server with one partition back from the service processor with no loss of production data. Your plan sounds valid and about what we did over a fuzzy and busy year ago.
