For ESCON it could be channel path exhaustion (for FICON also possible, but the limits are much hither). For most devices logical path limit is L=P*C L - limit P - lPars using the channel (in ONLINE) C - LCU aka CUADD aka logical control unit. You added 2 LPARs, so the number of logical paths required increased.

Check the control unit documentation for its limit. Each channel interface on the CU requires one logical path for each active LPAR sharing that physical path on a connected processor. Only active LPARs play, so you would always see any problem shift to the last LPARs to be activated. For example, If you have 16 physical paths from the processor to the control unit and share all those physical paths with each LPAR, then each LPAR you activate using those paths requires another 16 logical paths to the CU. Once you reach the supported logical path max of the CU, no more paths can be configured on line to that LPAR or any other LPAR. 8x16 = 128, so if the limit happened to be 128, with 16 logical paths/LPAR none would be left after 8 LPARs were active. If that's your problem, the only choice is to either configure fewer paths per LPAR so you can run more LPARs, or maybe upgrade to a CU that supports more logical paths, or change from ESCON to FICON so you don't need as many paths for same data bandwidth. I think you can release a logical path from an active LPAR by dynamically configuring the physical CHPID offline to that LPAR. I doubt if varying the logical path offline is sufficient. -- Joel C.
