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.
