Hi
We would like to categorize the channels as in the Mainframe Concept book
(http://publib.boulder.ibm.com/infocenter/zos/basics/index.jsp?topic=/com.ibm.zos.znetwork/znetwork_74.htm)
CCW channel or Coupling channel or QDIO/OSA.
Can I make this from the channel type codes ?
In fact you just did it.
What do you want to achieve?
I'm asking, because there are different point of view:
CHPID type - as in HCD, i.e. CNC, FC, FCV, CTC, etc. A physical channel
can be defined as one of allowable types. For ESCON you have 4 choices.
Channel card type - i.e. FICON Express2, Express4, Express8 - all those
cards support same set of CHPID types.
Channel media - related to Channel card type.
CPC - machine model sometimes decides wht CHPID can be used, i.e. CFR
cannot be defined on z9, even if the same card do support CFR.
CCW channels:
Bus&Tag, ESCON, FICON (no-Express, Express, Express2,4,8)
CHPID: BL, BY, CTC, CNC, CVC, CBY, FC, FCP, FCP
CF link channels:
ISC(fiber optic 2-3 generations), ICB (copper, several incompatible
generations, ICB, ICB-3, ICB-4), PSIFB (Infiniband), IC (internal,
emulated).
CHPID: CFP, CFR, CFS, CBP, CBR, CBS, ICP, ICR, ICS, CIB
Network channels:
Variuos OSA cards, IQD - emulated.
CHPID: OSA, OSE, OSD, OSC, OSN, IQD (and OSM, OSX for z196)
Remark: I intentionally excluded channel types available in Multiprise
machines (EIO, DSD, ISD) and machines older than 9672 (IOC).
