A fair number of people have reported that when they want to provision storage to a host this doesn’t seem to work. Only after bouncing a FC port or rebooting the host these LUNs become visible. Others reported that it only works when they provision LUNs and zones in a particular order. So how is this possible? Continue reading
Australia and the doomed NBN
In Australia there are basically two camps in the government that promote (or make it seem like they do) very fast internet connection speeds. The Labor party started this off a couple of years ago with the introduction of the NBN (National Broadband Network). Its intention is (or rather was) to provide almost every household in the nation a piece of fibre-glass to the front-door to be able to hook up current and future transmission technologies to be able to provide a multitude of services over the internet.

Supportsave…which one ???
Obviously when we need to analyze problems we need to have the correct data. No use of looking at tires when your headlight is broke. Continue reading
SUSE stops support for LibreOffice
On December 3rd SUSE announced it no longer supports LibreOffice as part of its core business. This doesn’t come as a surprise since LO is a pretty beefy environment by itself and requires some significant time and effort for qualification and ongoing support for customers who have bought this from them.

The forced marriage between Microsoft and Nokia
Unless you were in hibernation mode the last few days or were snorkelling somewhere in the middle of pacific you most likely have noticed that Microsoft have swallowed Nokia for a whopping 7.something billion dollars. For those who have kept their eyes open for the past few years you would have noticed this was more of less a forced marriage. Continue reading
Calculator via CLI
As an engineer dealing with storage I do get a hell-of-alot of info in either binary, hex, octal or decimal format. It’s always a PITA to convert these to human readable format. So i cooked up some bc functions and use these as a function in bash to beat the time wasted firing up the calculator or some weird stuff in LibreOffice Calc. Add the below in the .bashrc file and restart your shell.
function h2d { echo “obase=10; ibase=16; $( echo “$*” | sed -e ‘s/0x//g’ -e ‘s/\([a-z]\)/\u\1/g’ )” | bc; }
function h2b { echo “obase=2; ibase=16; $( echo “$*” | sed -e ‘s/0x//g’ -e ‘s/\([a-z]\)/\u\1/g’ )” | bc; }
function b2d { echo “obase=10; ibase=2; “$*”” | bc; }
function b2h { echo “0x$(echo “obase=16; ibase=2;”$*”” | bc)”; }
function d2b { echo “obase=2; ibase=10; “$*”” | bc; }
function d2h { echo “0x$(echo “obase=16; ibase=10; “$*”” | bc)”; }
So on the bash prompt:
[1423][erwin@monster:~]$ h2d 0x16
22
[1423][erwin@monster:~]$
Very handy.

Australian Internet access. (with handcuffs and chains.)
It may come to no surprise that if you want to rewire a country the size of Australia it’ll take a while. This means that the majority of internet connections is still on ADSL or ADSL2+. The outback is in really bad shape and people over there are relying on satlinks or wireless. This in turn ramps up costs significantly and thats also the reason why telcos and ISP’s are putting caps on subscriptions. Continue reading
