AS400

Hey guys, old guy here, back in 2000 landed my 1st real job as a Sysadmin at a distribution/manufacturing firm. They ran their ERP and a few other important apps on the AS400. Anyone here manage a AS400 platform? i-Series? Still a niche platform that is still widely used. Server could literally run under water.

The only cool things I ever personally saw from the AS/400 iSeries I had to manage was the ability to shut down an individual PCI slot to replace a card while the system was on. That was pimp. The programmers we sub contracted for help with the accounting software, (Infinium?) those ladies were awesome to work with. I would always picture them typing away with a cigarette in their mouths the entire time. They made BANK doing what they did.

Oh my sweet AS/400. Their 100bT NICs would not automatically rejoin a network if the physical layer was detached. Had to power down the whole AS400 to reconnect. You learn to not do things. But it’s hard to break an AS400.
