My company has an RS/6000 server and is running AIX 4.3.3. My boss asked me to upgrade the memory from 128 to 512. I haven't the slightest idea about Unix or booting, re-booting. I use Windows and I know to upgrade the memory on that you just shut down, install and restart and your ok. Is there any difference in this procedure with AIX 4.3.3. Anything I should look out for or commands for the server. I know this sounds stupid but I realy need to know. Thanks
