  3. What gets defined in HCD and in DFSMS? • The HCD definitions are different for the TS7680 than for either TS7700 or 3494 VTS. • For each Physical Controller (2), define 8 logical control units. • Controller 0 (Bottom) use CUADD = 0-7 • Controller 1 (Top) use CUADD = 0-7 • Do not use 0-F • For Device Strings (8 in each physical controller - 16 total – 256 virtual drives) use this range for the LIBPORT number assigned to each string of 16 devices. • For Controller 0 (Bottom) use (hex) 01-08 • For Controller 1 (Top) use (hex) 11-18 • This is true for the IOCP on any of the hosts.

  4. What gets defined in HCD and in DFSMS? • ANY system's SMS will see one Composite Library and zero Distributed Libraries. • Regardless of which controller’s drives it is attached to. • All systems use this one Composite library ID in their HCD

  5. What gets defined in HCD and in DFSMS? • Be sure to balance the loading on the two TS7680 Controllers by allowing an equal number of on-line virtual drives on each LPAR. • Make sure APARs OA26414 and OA30718 are installed for improved load balancing. • Each logical connection through a FICON port from an LPAR to a logical control unit consumes 1 logical path. • Since there are 256 logical paths per port, 32 LPARs can have a logical connection to all 8 control units in a physical Controller. • If there are more than 32 LPARs that need to be connected, then the number of control units’ drives brought online must be reduced such that 256 logical paths per port is not exceeded. • Otherwise, as LPARs are IPL’ed, only the Control Unit/Path combinations up to the 256limit have paths available to bring drives online. (First come, first served)

  6. The Examples Used in this Presentation • IOCP example is for a single TS7680 subsystem. • The Terms 'Director' and 'Switch' are Interchangeable. • In the examples, each controller has two FICON Channels. • Maximum is four • Four FICON Directors for Redundancy (Two cascaded pairs) • No single point of failure • Using IOCP for examples • Translate to HCD by using SG24-6266 FICON Native Implementation and Reference Guide (Redbook).

  7. The Examples Used in this Presentation, Director Switch ID • Director Switch ID is Defined in Director GUI Setup • Inboard Director Switch ID is used in the SWITCH= parameter inthe CHPID definition • Director Switch ID does not have to be the same as Director Address* • Examples use different ID and Address for clarity • Allowable Director Switch ID ranges established by manufacturer

  8. The Examples Used in this Presentation, Director Address or Domain ID • Director Address defined in Director GUI Setup • Director Domain ID is the same as Director Address • Outboard Director Address used in the LINK parameter on the CNTLUNIT definition • Director Address does not have to be the same as Director ID* • Allowable Director Address ranges established by manufacturer

  9. The Examples Used in this Presentation, Director Ports • Director Ports • Port Address may not be the same as Port Number • Port Number identifies the physical location of the port • Port Address is used to route packets • Inboard Director Port (to which the CPU is connected) is used by HCD, but not IOCP • Outboard Director Port (to which the control unit is connected) • Combined with Director Address in LINK parameter of CNTLUNIT Definition • Director Address (hex) combined with Port Address (hex) (two bytes) • Example: LINK=6106 would indicate Director Address of x'61' and "Port Address" of x'06'

  10. The Examples Used in this Presentation, Connections • External Director Connections • Inter-Switch Links (ISLs) connect to E Ports • FICON Channels connect to F Ports • Internal Director Connections • Port Type and Port-to-Port connections are defined using the Director's GUI Setup

  11. Definition Matrix Director Setup HCD IOCP Director ID Switch ID...... (Add Channel Path Panel) SWITCH= in CHIPID Definition Director Address or Domain ID Connected to Switches.... (Add Control Unit Panel) LINK=XXYY In CNTLUNIT Definition, Outboard Director, in first byte, (XX) Port Address Port......... (Add Control Unit Panel) LINK=XXYY In CNTLUNIT Definiton, Outboard Director, Outboard Port, in second byte (YY)
