Do you ever feel you wish you could answer some of your own questions when you work with AIX® and your System p™ server? Do you ever feel you could save time by not having to call on the support professionals all the time? Well, wish no more. Shiv Dutta discusses some of the AIX commands that answer those questions and tells you how to enlarge the list of such answers. Look at the below link for the Answer.
Most companies these days restrict their internet access by forcing the usage of web proxy. If your company is forcing a proxy policy & you are running Redhat/CentOs/Fedora you will have to update your yum.conf to be able to update your desktop or server using yum over a proxy connection. Luckily setting up yum to run over a proxy is an easy task. below is the few steps you need to follow to establish just that.
Edit the file/etc/yum.confand add the following lines:
# The proxy server - server: port proxy=http://proxy.mydomain.com:3128# If proxy authentication is required proxy_username=yum_user proxy_password=yun_user_passwordThe next step is to declare the variable http_proxy to run
when the yum rpm get executed to avoid the below error:
warning: rpmts_HdrFromFdno: Header V3 DSA signature: nokey, key

A crazy question huh. I was wondering how many people who will fall on my blog by mistake or even who meant to will know what AIX stand for. So I thought I will give a hint to all of you.
According towikipediaAIX(AdvancedInteractive eXecutive)is a proprietary UNIX operating system from IBM.Originally meant “Advanced IBM Unix” but the name probably was not approved by the legal department and was changed to “Advanced Interactive Executive
Its official development owner website is http://www-03.ibm.com/servers/aix/ further more the biggest addon to AIX from other Unix flavors is the SMIT administration tool, which is a text mode interface that easy administration tasks in AIX.
A typical AIX system administrator problem is the importance of these systems, and being not able to stop them at anytime & for any reason. A downtime on these AIX boxes are very expensive and the admin has to avoid at all cost. In the other hand, its often the case where the admin has to move the data from one disk to another without losing data. Furthermore, the admin has to avoid downtime while handling the migration. Few typical reasons why the admin need to migrate data between different disks or even storages are:
The requirment to move to a larger disk
The requirement to move to a different Raid Configuration disk
If you are looking for some IBM AIX / Pseries software, or even if you are looking for any IBM software in general then you must check out ftp://ftp.software.ibm.com/
The above ftp server is loaded with legal IBM software than you can use or just learn about them. Check it out & comment which of these tools were usefull for you.
Throughout the life of avolume group(VG) can happen a lot.The most common are in relation to its size or its physical volumes. Ah, I can hear a lot of you thinking about how to expand their volume :).
When changing the size of aphysical volume (PV)AIX does not realize it hot.In AIX boxes it is common that the disk is coming from an external storage (Ex: SAN) and some of the LUNs which correspond to devices that exist in hdiskX VG has been expanded.We recalculate the size of available disk with the following:
When you get to the most unfortunate time & you have a failure with your AIX box it get to be handy to have the list of AIX Error Codes and their diagnosis. Although googling & internet searching is invaluable options these days, when searching for a resolution for AIX ensure it is totally related to IBM AIX. For that the AIX error codes list provided by IBM becomes invaluable in these cases. Below is these codes for AIX running on IBM POWER 5 & IBM POWER 6:
This is a super funny video explaining why BSD is dying. You really should watch this for a good laugh :). Though Please don’t get us wrong we love BSD, but can’t persist this funny video.
FreeBSD 7.1 has been officially announced few weeks back, this version of FreeBSD has incorporated some changes and some improvements over its predecessor RELEASE FreeBSD 7.0 including:
The ULE scheduler is now the default in the kernel of the i386 and amd64 architectures.
DTrace is completely ported to FreeBSD from OpenSolaris.
BootLoader is amended to allow boot from USB devices.
Upgrade to KDE 3.5.10 and upgrade to GNOME 2.22.3.
Now we can download all the discs in one DVD just for the i386 and amd64 architectures (quite good news for those who bothered much of jogging cds all the time).
for those interested in learning more about new features, bugs fixes, changes in FreeBSD 7.1, please check theofficial FreeBSD announcement.
