This read-only INTEGER reports, per its source description, the current state of an ESCON station, moving through values like idle, cpDefined, cpReset, cpActive, cpDelete, cpAbend, several cldp (control link data protocol) states used for loading/dumping, deletePending, deleted, and cpXidExpected. Admins use this to track exactly where a given station is in its connection/definition lifecycle when diagnosing why a particular device on the ESCON channel isn't passing data as expected. For example, a station stuck in cpXidExpected rather than progressing to cpActive would suggest the expected exchange-identification handshake with the host never completed.
