Migrating to zOS R8 Part 1 - Messmer The Brain House

Migrating to z/OS R8 Part 1 of 3: Get Ready
Since z/OS V1R7, the contents of PSP buckets are no longer shipped with CBPDO and ServerPac orders. Instead of the
actual PSP information, you now receive the names of relevant upgrades and subsets, and you’re directed to the PSP
Web site (https://techsupport.services.ibm.com/server/390.psp390) for the contents of the buckets. This ensures that you
see the latest PSP information, as the PSP information that was provided with an order was current only on the day the
order was created.
The upgrade for the z/OS R8 PSP bucket is ZOSV1R8. Recognizing that there are many PSP buckets to review, z/OS
uses descriptive element names, instead of FMIDs for the subsets. This reduces the number of PSP buckets that must be
reviewed, since most elements are composed of multiple FMIDs. There are subsets in the ZOSV1R8 upgrade for general
topics (ZOSGEN), and for the ServerPac deliverable (SERVERPAC) that should be reviewed also. DFSMS is
consolidated into one subset. All PSP upgrades and subset IDs are listed in the z/OS Program Directory. However, the
non-exclusive elements' stand-alone product upgrade and subsets are used.
Hardware PSP upgrade identifiers
Hardware PSP bucket upgrade IDs are in the form xxxxDEVICE and contain the latest software dependencies for the
hardware, and recommended PTFs and APARs required for specific processor models. The PSP hardware upgrade
identifiers are:
w 2094DEVICE for the z9 EC server
w 2096DEVICE for the z9 BC server
w 2084DEVICE for the z990 server
w 2086DEVICE for the z890 server
w 2064DEVICE for the z900 server
w 2066DEVICE for the z800 server
Tip: To simplify finding the appropriate PSP bucket and identifying which PTFs listed in the PSP bucket need to be
installed on your system, you can use the Technical Help Database for Mainframe Preventive Service Planning Buckets
(http://www14.software.ibm.com/webapp/set2/psp/srchBroker) and the Enhanced PSP Tool (EPSPT). The Web site
provides a search capability as well as pull down lists for types of PSP buckets. The types supported include Processors,
z/OS, and Functions. So you can simply select the processor you are preparing for and click Go.
DASD Storage Requirements
If you are migrating to z/OS R8 from z/OS R5 or you will have a different product set than your previous release, you will
see increased need for DASD. How much more depends on what levels of products you are running. Keep in mind the
DASD required for your z/OS system includes (per the z/OS Policy). That is, it includes ALL elements, ALL features that
support dynamic enablement, regardless of your order, and ALL unpriced features that you ordered. This storage is in
addition to the storage required by other products you might have installed. All sizes include 15% freespace to
accommodate the installation of maintenance.
The total storage required for z/OS data sets is listed in the space table in the z/OS Program Directory and z/OS and
z/OS.e Planning for Installation.
For z/OS R8:
� The total storage required for all the target data sets is 5,456 cylinders on a 3390 device.
� The total storage required for all the distribution data sets listed in the space table is 7,362 cylinders on a 3390
device.
� The total HFS storage is 2,800 cylinders on a 3390 device for the ROOT HFS and 50 cylinders for the /etc HFS.
� The total storage required for the SMP/E SMPLTS is 0 3390 cylinders (there are no load modules in z/OS R8 that are
both cross-zone and use CALLLIBs, thus the SMPLTS is not needed for permanent storage for the z/OS product
itself).
