A little Linux success

After ranting about how difficult it was to install Linux on the blade (vs IBM i), I was hoping I’d get some quick resolution.  However, the scenario ended up like this:

The VIOS folks tossed it over the wall to the Linux folks.

The Linux folks determined that I did NOT have a support agreement for Linux on the blade.  They closed the call.

I reopened the call, arguing that the problem manifested itself when using the terminal window to install Linux but the terminal window, being a part of VIOS (IVM) would be part of a supported product.

Silence.

I then, through trial and error, determined it to be a Firefox issue.  I *could* install with IE8 but not with FF.  I reported this back to IBM expecting that they would proceed with determining the cause of the incompatibility and get it fixed.  Au Contraire!  Browser incompatibilities are not part of the mission of IBM support so they closed the call.

I did pick up this tidbit though, and I document it here so I can find it again: You can start the terminal for a given partition in VIOS by issuing the mkvt -ID X command  from the command line where X is the number of the partition.  To exit the partition terminal use the key combination ENTER, ~, . (period).   Whether the VIOS terminal is running in the “Remote Control” window from the AMM or from Telnet or SSH, the commands work.  So now I have a workaround.

I was able to finally get the SLES 11 Linux (PPC64)  partition running and accessible from VNC using a technique found at the Novell site where I posted. Read it all the way through.  The solution is posted at the end of the link in the post: http://forums.novell.com/novell-product-support-forums/suse-linux-enterprise-server-sles/sles-configure-administer/373530-sles-11-vnc-issue-no-desktop-just-gray.html

So that gets Linux (SLES 11 PPC64)  running again.  Now if I can get WAS 7 going on my i, the software application installation challenges for the week are done.

The easiest partition on a JS12 blade (is NOT Linux)

A few months back I participated in the IBM i 7.1 beta program and I absolutely marveled at how ridiculously simple it was to install i5/OS on a new partition.  Create the partition, activate it, use Operations Console to connect, bada bing!  start feeding the beast with DVD’s and …done.  It maybe took two hours start to finish.

Having experienced a quick and easy install with a “difficult” operating system, I decided to try something easy.  A well supported, well known, easy to install Linux distro.  Since Suse Linux Enterprise Server is supported in the Power PC 64 bit world, I downloaded SLES 11 and pulled up the install instructions and have now spent two days trying to get the distro to install.  I have posted to a few forums but apparently Linux on Power, particularly on a JS12 blade running VIOS and the IVM to install the OS is a bit of a mystery.

The maddening part is that I have done this somewhat successfully before but I am not making much progress at the moment. The issue is getting a terminal window to display so that I can begin the install process. The JS12 implementation guide says to start a Remote control session using the AMM (easy to do) and then activate the defined partition in the IVM (also easy to do), and use the IVM option to “Open a Terminal Window” (another easy step). So far so good. The part that doesn’t seem to be working is the “terminal window” popup in the IVM that is supposed to appear to authenticate only appears for a second or two and then it disappears without an opportunity to log in. The AMM Remote Control terminal window changes from displaying the VIOS console to a blank screen. Seems to me that in my last successful attempt at installing Linux using the IVM I saw all the installation prompts in the remote console of the AMM but I can’t be sure.

The missing terminal window is a show stopper since there is no way to install the OS headless.  In fact, the original install of SLES11 was deleted because I couldn’t get the GUI to ever run, even after installing the OS in text mode (which is no easy feat).

Ah! Would it were that Linux was as easy to install as i5/OS!  Whenever I DO get it installed, I will post the “trick” here (whatever it is) so at least I can find it again…

The end of the rainbow

Somewhere over the rainbow, bluebirds fly…

Yes! The JS12 is still rockin and rolling so we are finally out of the woods and can once again rely on the trusty i to keep going and going.  There are still a couple of mysteries to solve: The bang! light on the SAS Connectivity Module when the tape drive is plugged in (it works though) and the mysterious “Message ID . . . . . . :   CPF9E7F” i5/OS usage limit exceeded message.  — Current processor usage across all active i5/OS partitions is 2.00  — Current processor usage for the local partition is 1.00.

Since I only have a single processor allocated to the i partition and and only one i partition configured, IBM and myself haven’t been able to figure out why i5/OS is still reporting 2 processors active for i5/OS.  PTF to come, no doubt.

Looking into some Ruby 1.9 issues and some other odds and ends while still trying to make ends meet by consulting.  At least I have a machine I can work with and I can, once again, pull the plug on the 270.

Hope to report on some CRUD frameworks in an upcoming post.  Busy as ever, but more productive now that I am not burning up time trying to keep the JS12 running…
