We have some problems witch channels to the FICON SAN switches: channel 56 on Mainframe1 to switch 5B5 (FDBELF5C1_VSAN500_DISK) and channel 28 (on Mainframe1) to switch 5B7 (FDBELF5C1_VSAN510_TAPE). Forr Mainframe2 the channels are 35 to 5B5 and 37 to 5B7.
Hereby an example for switch 5B5 and channels 56 (BAD) and 43 (GOOD):

When one tries to put the path online then the following error messages are seen:

We don't think that the problem is port related but switch related!
For the moment problems are present on only one of our 4 mainframe SAN directors. Firmware level of the directors was changed 3 weeks ago to NX-OS 4.2(7b).
