New pastures

Today is my last day as an employee at IBM. Its been fantastic. I’ve had a great experience to learn about this business of scale-out computing. I’ve met with some bright minds and gained experiences I could have no where else. I’ve been able to visit data centers of nearly every big company in the…

updating iDataPlex IMM firmware

Easiest way is to do it remotely. First, get the package from IBM, then copy the file to some directory. Then do the following: chmod 755 ibm_fw_imm_yuoo* ./ibm_fw_imm_yuoo48d_linux_32-64.bin -x . Now you have a bunch of files in this directory. This machine could be a laptop or whatever. Now you can remotely update the IMM…

IBM acronyms

There are many… But these are the ones I hear and need to remember: DAU – Demand Acceleration Unit (Early release machine that IBM sometimes gives to customers to evaluate.) BMC – Base Manufacturing Cost (Cost for parts) TMC – Total Manufacturing Cost (Total cost including labor) VLH – Vendor Logo Hardware – Hardware that…

QLogic debuging

Fedora 11 Kickstart and SATA drives

My Fedora 11 Kickstart installs fail if I have the drive line look like this: part / –size 1 –grow –fstype ext3 I was able to make it work by giving it a real size: part / –size 10240 –fstype ext3 That seemed to make it work.  I also noted that this bug has already…

Using IBM Bootable Media Creator with xCAT

With a few hacks I was able to get somewhere with this… I wasn’t able to update everything nor restore the bios. 1.  I downloaded the tool from IBM site:  http://www-947.ibm.com/systems/support/supportsite.wss/docdisplay?lndocid=MIGR-5079820&brandind=5000008 2.  I put this in the /tftpboot/bomc directory. 3.  Copied /tftpboot/bomc/[tcrootfs|tc.zip] into /tftpboot 4.  Edited /opt/xcat/lib/perl/xCAT_plugin/dhcpd.pm line 282 made the filename say “bomc/pxelinux.0” instead…

jquery ui tabs and the back button

For the site I help out with, xcat.sf.net, I used jquery-ui tabs.  The only issue I had was that I couldn’t do back button, and I started getting a few complaints from it… So, after about 20 minutes of investigation, here is the code I used to make it work.  It works pretty well for…

IPMI settings.

Some times configuring the BMC’s or IMM’s with xCAT is not possible. So you may want to do settings without xCAT. Here are some tricks with our handy tool: ipmitool See current IP settings: ipmitool lan print 1 This is great for looking at IP addresses and stuff. ipmitool -I lan -H 172.29.101.2 -P PASSW0RD…

VMware Fusion: Specify physical connection

In Windows I was able to do this from the VMware interface, but on Fusion I have to hard code it.  This link shows how its done: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1001875 Not that cool…  But at least its possible.

iphone voice mail issues

All the sudden I stopped getting voicemail. I thought perhaps nobody wanted to leave me any messages. I was fine with that. Then I tried it myself. Lo and behold! It just stopped working! This is yet another example of the lameness of AT&T and the iPhone. I can tell you that people like me…
