In the absence of the exact details of the failed 'cards', if, as has been mentioned by others these were ESCON cards and after failure the customer may have decided to 'enable' additional ESCON ports then a 'recode' (to the die-hard MFers it's LIC-CC) is required.
It's been such a long time but from memory: 16-port ESCON feature: The feature has 16 ports, up to a maximum of 15 active ESCON channels per feature. There is a minimum of one spare port per feature to allow for channel sparing in the event of a failure of one of the other ports on the same ESCON channel card. 16-port ESCON channel port enablement: The 16-port ESCON feature channel cards are initially installed as a pair, and then in increments of one. The 15 active ports on each 16-port ESCON feature are activated in groups of four ports via Licensed Internal Code - Control Code (LIC-CC). If it was a single port failure, then the failing port would have swapped to the 'spare'. From the little info available, it seems it was a complete card(s) failure. If this was FICON 'card' then the need to 'recode' doesn't make any sense!

I have been in this industry for 50 years. I have never seen anything like the following: House Technology and Infrastructure Committee Chairman Del. Daniel Linville, R-Cabell, said that two mainframe parts failed at the same time. “The parts were not available for the both of them here in town,” Linville said. “Because of that very unfortunate set of circumstances, multiple parts had to be ordered, and get here as quickly as possible.” . . . Linville said as of Thursday morning at 10 a.m.,the parts were in, but functionality had not yet been restored and the manufacturer had to recode the system. So let me get this straight: Parts fail, you replace them, then recode the system? I am at a loss as to exactly what Mainframe works like this. IBM is making the only true business mainframe, and I have been there for loads of parts replacements, and I have NEVER had to "recode" the system afterward. I wonder what credentials Mr. Linville brings to the table to make these pronouncements. But Larry Linville was Maj. Frank Burns, and no one in the 4077th except Hot Lips was impressed with his knowledge or skill.... Just sayin'....
