Chapter 14. Data migration in zSeries environments 313
To show how powerful, meaningful naming conventions for VOLSERs might be combined
with the selection capabilities in ISMF, Example 14-13 shows an example of how to change
the status of 920 volumes at once. This example assumes a contiguous number range for the
volume serial numbers.
Example 14-13 Indicate SMS volume status change for 920 volumes
STORAGE GROUP VOLUME SELECTION
Command ===>
CDS Name . . . . . : SYS1.DFSMS.SCDS
Storage Group Name : XC
Storage Group Type : POOL
Select One of the following Options:
3 1. Display - Display SMS Volume Statuses (Pool & Copy Pool Backup only)
2. Define - Add Volumes to Volume Serial Number List
3. Alter - Alter Volume Statuses (Pool & Copy Pool Backup only)
4. Delete - Delete Volumes from Volume Serial Number List
Specify a Single Volume (in Prefix), or Range of Volumes:
Prefix From To Suffix Type
______ ______ ______ _____ _
===> DB2 001 300 X
===> IMS 001 350 x
===> LRG 001 150 X
===> TMP 001 120 x
Use ENTER to Perform Selection;
Use HELP Command for Help; Use END Command to Exit.
Through this approach in utilizing the SMS volume status, the data gradually moves to the
new environment. This is not the fastest approach, but it is the approach with the least effort
required. To speed up the process you run DFSMSdss full volume logical copy operations on
all source volumes as suggested by the storage administrator, but do not specify target
volumes. An example is given in Example 14-6 on page 307. Then allocation runs through the
standard SMS allocation and automatically selects the correct target volume, and moves the
data sets, which are not allocated at the time the job executes. Another option is to run
DFSMSdss migration not on a volume level, which allows more control, but plan for
DFSMSdss migration jobs on the entire SG level, perhaps over the weekend. Figure 14-14
illustrates this. You might specify for STORGRP a list of storage group names to address
multiple storage groups at the same time.
Example 14-14 DFSMSdss moves all data sets out of a storage group
