New task at hand fellow UNIX Administrators. Now we need to discover the new (EMC) LUNs presented by the Storage team and make it available into Veritas Volume Manager (VxVM) and extend one of the filesystem under Veritas Filesystem (VxFS).

Extend Filesystem under VxVM
We have already discussed extending a filesystem in AIX under JFS as well as the basic of softpartion where we could also extend its filesystem size. This time we have a task which is under Veritas Volume Manager (VxVM). We need to extend a partition that is being managed by VxVM.
How to use snap command on AIX
For any software or hardware issues with AIX, logging a case with IBM – the support team will always ask for snap files. Snap files will collect all system configuration that will help and guide the IBM support team to track whatever issue there is on the system.
Fix Garbled Solaris Console
If ever you encounter a console with output such as below, it can be easily be remedied by fixing the /etc/ttydefs file.

Merge Files in UNIX / Linux Systems
In response from our last post regarding splitting of large files, we will now discuss on merging these files for us to be able to use it again. We will also be discussing on checking the md5 hash and chksum.
Split Large Files in UNIX / Linux Systems
We have a very large core file and we need this to send to our vendor for analysis. The gzip’d file of the core is 20GB and the FTP server of the vendor does not like that. Therefore we need to split our very large file to smaller chunks that the FTP server would accept.
Reset RSC thru Solaris
We have to patch a Sun V480 and during the pre-tasks we have to check on the console of the box. To our surprise (or not) the console is hung. We have to reset the Remote System Console (RSC) for to be able to use it again. Here are the simple guide on how to reset the RSC thru the OS.
Grow filesystem under VxVM
We have already discussed extending a filesystem in AIX under JFS as well as the basic of softpartion where we could also extend its filesystem size. This time we have a task which is under Veritas Volume Manager (VxVM). We need to extend a partition that is being managed by VxVM.
Kill All Processes by User in UNIX
An application user asks to kill all the processes under their application account. When you checked on the box itself you saw a lot of processes and killing them one by one would take forever.
Free up space hogged by application in UNIX
Hey, what do we have a here? The df command says that our filesystem is 100% but after thorough examination you see that the filesystem is almost empty. This is caused by applications (most of the times poorly coded) which are still hogging the space that was originally used by the deleted file.
