There are a bunch of runlevel for UNIX or Linux which is also called init level or mode of operation. Usually there are seven init or runlevels (0 to 6). Only one runlevel can be running at a single time.
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).
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.
If ever you encounter a console with output such as below, it can be easily be remedied by fixing the /etc/ttydefs file.
Managing printer is one of the least task of a Unix System Admin. But printer management is typically easy to get along with as there is just minimal commands and options that we use. Here are some of my trusted commands to manage printers:
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.
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.
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.
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.
