I need to know the LPAR structure on my AIX server - How many LPARs, what is installed on each, are there any free LPARs, memory size, disk space available etc.

I tried "vmstat" and "lparstat" commands but I need more info.

I read about HMC to get the above info. What is HMC and how can I get to it? (I am totally new to this, so pardon the ignorance).

HMC is the Hardware Management Console. This is an appliance that is used to manage the physical servers and the LPAR configuration. If your LPARs are configured correctly you should be able to display the address of the HMC which manages an LPAR using the following command:

lsrsrc IBM.ManagementServer

And to access it, assuming you have a recent version of the HMC software, you can try hitting the HMC logon page by pointing your browser to

https://<xxx>/preloginmonitor/index.jsp

where <xxx> is the value of Name or Hostname from the lsrsrc IBM.ManagementServer output.

You can read more about HMC here.

Awesome! Using your replies, I was able to reach the login page of HMC.

How ever I am unable to login! :-(

Question 1: The server I am trying to get LPAR info about is, lets call it Server A. When the HMC login page showed up (its version V7R3.5.0.2), I notice the browser title shows ServerB:HMC

Can the HMC be on a different server?

Question 2: I am unable to login to HMC using credentials of Server A. (I ran the lparstat commands by puttying into Server A using the same credentials). Am I missing something?

Thanks again for the help!

What's the deal here? Are you the administrator for the HMC and its LPARs? If so, you should have the login/pw. If not, you shouldn't be messing with this and you should really talk to your SysAdmin.

The HMC is a completely different system than your LPAR and has
completely different authentication.

Maybe you should find a sys admin at your location who can login.

What about HMC commandline? can I access that with the user credentials I have for Server A?

Originally posted by: unixgrl

No. command-line and GUI use same credentials.
It is possible to setup LDAP on the HMC which would allow you to use your serverA credentials but it doesn't sound like you have HMC access.

You might want to try to login with the default password for hscroot which is abc123. But as orphy said earlier, if you are not really the admin for this box you shouldn't be messing around with it.

Nope I am not an admin. But we need to order some hardware for app development and I am tired of waiting for the sysadmins to get back to us with the current server anatomy.

I only wanted to login and see how the current landscape looks like. Nothing heinous :-)

That is HAW-T-T-E-E. At my last job, Id've made you a job offer off of the street. If I could find 3 develoeprs within the 6 billion people on this planet that motivated, we could've solved every problem we ever had.

Wish I knew where this guy worked so I could contact the sysadmins and alert them to the tampering....
If they are dragging their heels , maybe they are tired of the squeeky wheel !!!!

That's analougous to asking: "Who is Tyler Durden?"

The HMC manages your p/series IBM boxes and provides the mgmnt interface for instantiating LPARS.

It's an x/series box running IBM Linux that sits int he same rack and talks to the VIO2 cards in each POWER box via private ethernet
