Not seeing a newer guide, but this one will walk you through it: OSA-Express Integrated Console Controller Implementation Guide (SG24-6364-01).
Believe the gist you are looking for lies between the IODF RESOURCE macro statement and OSA-ICC CONFIG_SESSION source file. Let's say two systems (SYSA and SYSB) share the same UCB (C00). The pertinent part of the RESOURCE statement is (name, MIF image ID) and the equivalent piece in the CONFIG_SESSION file is IID=nn (MIF image ID). Abbreviated example below. IODF: RESOURCE PARTITION=((CSS(0),(SYSA,1),(SYSB,2)… CHPID PATH… CNTLUNIT CUNUMBR… IODEVICE ADDRESS=(C00,001)… OSA-ICC: <CONFIG_SESSION> <SESSION1> CSS= 00 IID= 01 DEVICE= C00 … </SESSION1> <SESSION2> CSS= 00 IID= 02 DEVICE= C00 … </SESSION2> </CONFIG_SESSION> Regards, Kevin -----Original Message----- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of linda golding Sent: Friday, June 10, 2016 4:24 AM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Query on OSA-ICC consoles Thought to post this question as i couldn't find this information in any of the IBM documentation . Does anyone know how OSA-ICC devices (3270-X) are mapped in HSA ? I did a search in our systems and see that OSA-ICC devices are concurrently active on all LPARS of the sysplex . I also see that PCHID is same across all the systems . I am just trying to find out how multiple systems can write on to the same physical OSA-ICC device ?..Basically i would like to know how this happens at hardware level . Any pointers /documentation would be a great help .
