HMC and VIO / VTY0

[tcorum]

I am trying to connect a few servers to an HMC. All was going well but one of the servers does not have VTY0. As I started to investigate it I found it also did not have any of the VIO devices defined. Anyone have any idea what could be the issue with this one server?

Thanks,

OK, what type of server and what OS version is running on that server?

HTH,

prtconf | head
and
oslevel
should do for starters.

only power5 and 6 have virtualisation capabilities
only aix 5.3 and 6 will configure vty, previous versions use tty.

The servers were already up and running?

Maybe the servers are in MDC mode (Manufacturer Default Configuration). This happens when buying the server without HMC, it only has one LPAR that uses all the resources and by default it uses the integrated serial as console, not the virtual one from the HMC.

If this is the case you must power off the LPAR and then power it on changing MDC to LPAR mode (it is explained in the power on pop-up menu). It may happen that when you power off the LPAR the entire chasis is also powered off, in this case you must first power on the chasis but indicating LPAR stand-by mode, so the LPAR doesn't boot automatically.
