Re: HMC and Service Processor issue - can't access the HMC

[PaulMmn <PaulMmn@xxxxxxxxxxxxx>]

I'm an amateur when it comes to the details of the HMC, but here goes:


I remember reading that once you have an HMC, 
that's the only offical way to administer the 
partitions.

I'm assuming that the LPARs in question are 
totally shut down.  Is anything awake on those 
LPARs?

What's changed?  PTFs?  Any PTFs for the service processor being applied?

Can you ping anything?  Any of the LPARs?

Check the HMC configuration-- does it have the 
correct IP addresses of the LPARs?

Can you see any Managed Systems in the HMC?

You should (theoretically) be able to click on 
Systems MAnagement/Servers/Connection Status/ 
Service Processor Status...


Any information on what's alive will be useful...
