HYPERPAV PAGING PERFORMANCE ISSUES WHEN WLMPAV=NO IN HCD
Symptom .. IN INCORROUT Status ... CLOSED
Hi,
We are defining hcd for an emc's dmx4 subsystem for use with hyperpav. Can I
define all 256 addresses from an LCU as base devices, and define another LCU
just for hyperpav aliases???
TIA,
Peter

Issues regarding ASM Paging to Hyperpav volumes have been
discussed several times on IBM-MAIN over the past few years.
APAR OA32453 has been opened to deal with these issues.

If many LSSs are involved, then pick a quiet time to perform the SETIOS
HYPERPAV=YES command ...Because it can take some time

Is there a way to get an estimation on time needed per LCU
Hi list,
We have two systems - SYSA and SYSB that are in SYSPLEX1 and see all
DASDs. We have five CU in Static PAV and all the others are Dynamic
PAV, and we want to start using HYPERPAV but have some questions that
couldn't find answer to :

We are running with Hitachi USP V disks. HyperPAV requires an additional
licensing cost for the OS and for the controller (license + additional
maintenance cost, if I remember correctly). I have no idea what the costs are,
as they are handled by a different department in our shop, and they also
What type of DASD are you running on? We're looking into going to Hyper-
PAVs and I heard there is a one-time Hyper-PAV license fee. Anyone know
how much that cost?

Hello,
We are going to enable HyperPAV in our shop (z10, z/OS 1.9, USP V) and we
currently do NOT have I/O priority management enabled.
Having read that HyperPAV uses IORP, we were wondering if we can enable
HyperPAV without enabling WLM I/O priority management.
Does anyone have any experience

We are running (z9BC, z/OS 1.9, USP V) and HyperPav seems to finally run
OK without WLM I/O priority management. Of course it took forever to get
VION to define the 'aliases' in their box but once they got off

Any guidance is appreciated.

I found APAR OA13915 that adds support for HyperPAV to z/OS. However, I
could not tell if there were any other changes required for HyperPAV use.
If you are using HyperPAV, could you tell me if there are any other changes
in addition to the installation of the APAR?

Yes. IECIOSxx would need HYPERPAV=YES and the storage subsystem would
also have to be licensed for it as well.

HyperPAV allows an alias address
to be used to access any base on
the same control unit image per
I/O base.
So does that takes the dynamic alias assignments by WLM out of the picture?
Are the alias to base assignments (if that is still a valid relationship

You can switch between HYPERPAV and WLM Managed PAV
