Hi List, Early in dec I was forced to upgrade one of my server systems - initially built in 2004 on an intel server mb it finally failed. Under some time pressure, I replaced the mb etc with a 64 bit asus system and did a repair of the linux system upon reboot with a 64 bit DVD. As one can imagine there were some headaches as the kernel was now 64 bit, but yum and friends were still 32 bit. I managed to upgrade the required packages to 64 bit, rebooted the server a few times and all appeared to function ok. BTW the server runs bind, apache, postfix, dovecot, mysql, php and related stuff.
I have now relocated the server in a lights off situation and myself to the other side of the planet. Why all the history - well as I ssh into the box and do my weekly yum updates, I find that there have been no updates, however all my other servers have had multiple updates.
Thus I did a rpm -qa and find there are only 65 rpm files listed - they are all 64 bit or noarch - none of the core server files are present.
How do I systematically update all the files from 32 bit to 64 bit? As I am unable to physically get in front of this machine, I have zero room for error - and need the machine to be up and operating each business day. My google searches have not given me any hits that help. Any help, directions, things to be aware off etc - appreciated. TIA

I can't help with the 64-bit upgrade, though I suspect that will be extremely touchy if it's possible, but for a server like that which is business critical, you MUST add some kind of remote console access. There is no question of "if", only "when" you will need it, like a reboot that needs you to press F1 or something. Attempting to perform this kind of upgrade without that would be very foolish.
If it's Dell you can add a DRAC card (used ones are not that expensive), or any other brand name will have something similar. If it's not a brand name you can get pretty close using a Lantronix Spider and a remote power switch. The system board might already have a BMC with some ability for remote access.
Fix the remote access problem before trying the 64-bit upgrade.

Noted and agreed, unfortunately life stuff happened, so now I will look for a separate power device that I can remote control.
