HP XP P9000 for Compatible PAV Software Licenses - Manual (Page 10)

Requirements Item
Hyper Parallel Access Volumes Parallel Access Volumes
Thin Provisioning Z
:
When you use z/VM, you must use z/OS as a guest OS on z/VM.
Functions incompatible with Parallel Access Volumes
Devices using Parallel Access Volumes can coexist in the same storage system but cannot be used
concurrently with the following functions:
•
Open Volume Management
•
Cache Residency
•
LUN Manager
•
Business Copy
•
Continuous Access Synchronous
•
Continuous Access Journal
Devices using Data Exchange cannot coexist in the same CU with devices using Parallel Access
Volumes.
IBM CC and Extended Remote Copy (XRC) for Mainframe restrictions
For Concurrent Copy (CC) and Compatible XRC, the 2105 and 2107 controller emulation types
cannot be intermixed with other emulation types within the same storage system.
Sharing Parallel Access Volumes across multiple sysplexes
Parallel Access Volumes functionality can be shared across multiple sysplexes that are on a single
storage system.
When sharing static Parallel Access Volumes, all connected systems must be in static mode. When
sharing dynamic Parallel Access Volumes, the following requirements and restrictions apply:
•
Only one sysplex should be running in Dynamic Alias Management mode. This master sysplex
is the only sysplex in the storage system that assigns aliases.
•
For all other connected sysplexes, the WLMPAV (HCD) and Dynamic Alias Management
(WLM) settings should be set to No.
NOTE: If more than one sysplex has the Dynamic Alias Management enabled, unsynchronized
alias transition and unpredictable response times may occur.
Preventive Service Planning
If you are using the Parallel Access Volumes feature on 2105 or 2107 device types, you are
encouraged to obtain the Preventive Service Planning (PSP) document from IBM to use as a program
temporary fix (PTF) source. The title of the document is 2105M VSESA, and it can be downloaded
via IBMLINK.
The PSP document identifies all current IBM PTF items applicable for z/OS and OS/390 support
of the 2105 or 2107 device types. The P9500 storage system does not have any specific PTF
requirements beyond what is required by the z/OS and OS/390 operating system to provide
minimum support for the 2105 or 2107 device types.
