Hi All

,

Motto : I am in need of IBM-AIX INTERVIEW QUESTIONS.

I am working as an a operator, on solaris 5.10 env. i have got an opportunity of IBM-AIX Administrator Job. I really don't want to miss this opportunity.

By the way i have basic knowledge of Solaris UNIX, I have confident i will clear 1st level of interview which will be interviewed by HR. But next round i will be facing to IBM-AIX Administrator and definately he will be bowling with technical question of which i am not aware

. Therefore i need help of you guys as i dont know what kind of question he would ask me on AIX.

Everyone's help would be appreciated. If possible please advise me with some common question which are asked by AIX-Admins, It would be great help

.

Thanks & Regards,
Imran

Depends on if you told you have AIX knowledge or not and are willing to get it.
So if they know you didn't work with AIX and they are no morons, they would ask you somewhat generic questions, I guess.

Maybe read up about ODM, LVM and smit, which might be the most significant differences though I have never touched a Solaris box yet.

Depends on where you work I guess.
Usually you have to care for the systems, check that no filesystem is getting full (df), check local mails (mail) sometimes, do shell scripting to make your day easier ie. write scripts that do checks on stuff like that mentioned checking for free filesystems.
You will also add/modify/delete users, groups, filesystems, directories and files etc., alter permissions etc., configure hardware and so on.

I wrote a categorized list for AIX/Linux commands for our apprentices - maybe it helps a bit to look up which commands might be interessting.

Code:

        LINUX                   AIX

        wget                    -
        yast                    smit(ty)

It would be rediculous to demand that you know many or the half of them as an operator, I think. But maybe you can surprise them

Oh, the list is a bit messed up sorry - I try to fix that. Basically it has 2 columns

and at the end "yast" is especially for SuSE Linux.

You want to be asked Solaris questions? In the beginning you said you applied for an AIX admin job

For Solaris I can't ask you anything, but there is a Solaris subforum too. I doubt that many Solaris people look into the AIX subforum.
