I have an openpower 710 system that was once configured with HMC for LPAR. Unfortunately I lost access to that HMC and cannot control the openpower Now I want to run suse10 Enterprise with Xen and want to use use Xen virtual machines. Could any body point me in the right direction how can I connect to openpower without HMC and how can I install SUse10
Thanks for your help in advance

Re: Open Power 7102006-08-10T14:31:00Z in response to SystemAdminSince you don't have access to the HMC anymore, I think the quickest way to do this is to log into ASM. This can be done by plugging an Ethernet cable from your laptop to HMC port 2. With most recent laptops you won't need a cross-over cable. The default IP address on the HMC port 2 is 192.168.3.147, so address you laptop to something on the same subnet. Then use a browser and access ASM with the IP address of HMC port 2.
Once in ASM, I believe you can reset the machine to factory defaults. Be careful as this may also downgrade your firmware level if you have not applied it to permanent (something you might consider doing before resetting it).
Once reset, you can use ASM to control the power on the server and also use serial or video console.
Check out this paper for more information on working with ASM -> http://www-128.ibm.com/developerworks/library/l-pow-opsetup/index.html
Re: Open Power 7102006-08-15T22:00:08Z in response to rangerusing the IP 192.168.3.147 and HMC port i cannot access the ASm I tried both
192.168.3.147 and 192.168.2.147 and both HMC1 and HMC2 ports
and cannot even acess the serial console. Well we used HMC previously to create LPAR on this m/c is that a problem ?
Re: Open Power 7102006-08-13T22:11:15Z in response to SystemAdminThanks a lot for your help. I will ceratilny try connecting through ASM , Thanks ranger for the suggestion . My problem is I do not have HMC. when we got these machines we were told that very shortly IBM is releasing the capability to control the lpars from one of its partitions , But I guess that never happened. Today i come across another piese of software called hercules-390 http://groups.yahoo.com/group/hercules-390/message/38526
It would be nice to know if its possible to emulate the job of HMC with this ?
Re: Open Power 7102006-08-13T22:22:31Z in response to SystemAdminHmm...I don't know anything about that link.
You can do virtualization on pSeries servers without an HMC using something called "IVM" (Integrated Virtualization Manager"?) that runs in a partition.
See http://www-03.ibm.com/developerworks/blogs/page/virtualization?entry=we_announced_ivm for some info.
Re: Open Power 7102006-08-17T05:15:34Z in response to SystemAdminThe Integrated Virtualization Manager (IVM) come with the VIO Server, when you get the Advanced POWER Virtualization (APV) feature.
When the OpenPower 710 is setup, it can either be configured to be managed by an HMC or IVM, but not both.
Here is an article that explains how to use IVM with Linux on POWER.

Re: Open Power 7102009-04-16T19:17:46Z in response to SystemAdminHi bobby-earth,
how did you solved your serial access issue? We run exactly in the same situation.
Got used openpower systems and have no serial or ip access over the default ip's.
Thanks a lot.
