I'm a bit confused. IBM Trusted Key Entry (TKE) Workstation microcode updates
are performed by an IBM Customer Engineer (CE). If you have separation of
duties-related concerns that's perfectly fine, but you still should have IBM CE
assistance available — you can ask the CE, basically, and then decide who
actually physically performs certain steps. (Recently there's also a
network-based USB-less microcode update method, but at least for now you should
still have an IBM CE available with your machine warranty/maintenance. On-site,
even.)
Part of the TKE microcode upgrade process involves backing up the critical
parameters and other site/customer-specific data from your TKE Workstation. You
can back up that data to a USB memory key/drive. But that's a "closed loop."
The TKE Workstation formats the drive ("TKEDATA" format) for you. There's
nothing to do on a PC, Mac, or other device.
Am I missing anything?
