2. What gets defined in HCD and in DFSMS?
The HCD definitions are different for the TS7700 than it was for either the standalone B20 or the PtP.
The most notable aspect is the range of the LIBPORT number assigned to each string of 16 devices.
For Cluster 0 this is the familiar 01-10
For Cluster 1 use 41-50
For Cluster 2 use 81-90
For Cluster 3 use C1-D0
This is true for the IOCP on any of the hosts.

3. What gets defined in HCD and in DFSMS?
Each Cluster should be defimed to SMS but there is no requirement that any particular cluster's virtual drives are defined in any particular system’s HCD.
ANY system's SMS will see 1 2 3or 4 distributed libraries.
Regardless of which cluster’s drives it is attached to.
Distributed Libraries are analogous to the clusters
Only one composite library.
All systems use this one composite library ID in their HCD

4. What get s defined in HCD and in DFSMS?
Each system accessing the composite library needs to have SOME but not all virtual drives online.
These drives can be on only one cluster, or two clusters or all clusters.
Any cluster can be a full participant in the composite library without having ANY virtual drives online to ANY hosts
For most configurations, I would expect local hosts to have virtual drives online from the local clusters and NOT the drives in the remote clusters.
I would also expect that any remote systems would have remote drives online, and NOT local drives.
Any additional connections would have to be made by channel extenders
Given this setup, any virtual drives can mount any virtual volume in the composite library, no matter where it resides.
What get s defined in HCD and in DFSMS?

5. What get s defined in HCD and in DFSMS?
Each FICON port on the TS7700 Vnode allows for 256 Paths
Each logical connection through the port from an LPAR to a logical control unit consumes 1 logical path.
Therefore 16 LPARs can have a logical connection to all 16 control units in a Vnode
If there are more than 16 LPARs connected then the number of control units’ drives brought online must be reduced such that 256 logical paths is not exceeded.
Otherwise, as LPARs are initialized, only the Control Unit/Path combinations up to the limit have paths available to bring drives online. (First come, first served)
See Logical Path Spread sheet included in this Techdoc Item

6. The Examples Used in this Presentation
IOCP example is for a two cluster grid.
The Terms 'Director' and 'Switch' are Interchangeable.
TS7740 V06 with Four FICON Channels
Four FICON Directors for Redundancy (Two cascaded pairs)
No single point of failure
Using IOCP for examples
Translate to HCD by using SG 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 in the 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
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
