What Happens When This is Turned OFF ?
Long, long ago in a place far, far away I was a Netware Master CNE supporting a good sized business with a large customer service department taking phone orders for their sales people. Custom order entry system ran on a COMPAQ (tells you how long ago this was) SystemPRO server running Netware. My manager and I spent the weekend installing a second identical server, matched all firmware versions, upgraded both systems to their fault tolerant version SFT III along with adding more hard drives and memory and some special fiber optic boards that mirrored everything between the two systems. A LONG weekend, but all was up and running fine on Monday, until.... one of the big wigs arrived to see how everything was going. He asked a lot of questions, and then asked what happens when one goes down and proceeds to power one system OFF. I think my heart stopped, but the application stayed working and the orders kept coming in.
Note: almost lost the account when I pointed out the 80MB hard drive in the SystemPro array that fit in my hand was the same capacity as the large washing-machine size drives on their UNISYS system :)
