Workload Partition (WPAR) - Sharing filesystem Global AIX to WPAR
I got another WPAR question today: From the Global AIX, I can add a filesystem to /wpars/WPARname/directory so the WPAR has access but what if I don't want to have the filesystem mounted there in the Global AIX? For example: I have a Global AIX filesystem called /tools that I want to mount in to one or many WPARs and appear and /temp in the WPAR(s)? My first answer is well you can use NFS because I do that all the time and I am a heavy user of NFS - no jokes please. I use NFS heavily! If the NFS server exports the mount point for every... [More]

It took me a good few minutes to find out how to do it and thought I would shared it to save you time: Use: uname -W It returns 0 for the Global AIX and a regular AIX or if it is in a WPAR it returns the WPAR Number (i.e. non-zero) Below we show how to use this in a script. wparno=`uname -W` if (( $wparno == "0" )) then echo Global AIX else echo...
