I noticed a little difference in tape ucbs IOGEN from one site to another –
Site 1. DEVICE (F000-F0FF)
Site 2.DEVICE (F000-F0FF)
What is the recommended setting for tape ucb AUTOSWITCH setting for MIA?
Is it ok to have AUTOSWITCH=YES for MIA?
Release : 12.5
Component : MIA
MIM cannot be configured to utilize AUTOSWITCH.
During startup, MIA examines the IOGEN attributes of all managed tape devices and if it detects AUTOSWITCH=YES it changes it to no and produces MIM2154W MVS AUTOSWITCHING TURNED OFF FOR DEVICE dddd
The MIM Programming Guide contains additional information in the section on Configure Tape Devices Offline until MIA Synchronization.
