For PDSE sharing, DFSMS has two groups named as follows:

• SYSIGW00
• SYSIGW01

Each group has the number of members calculated by the following:

 members = 1 + n
 Where:  n = number of systems in the sysplex with DFSMS installed

For example, in a sysplex of four systems that have two systems installed with DFSMS, SYSIGW00 and SYSIGW01 each have three members (SYSIGW00 = 1 + 2 = 3 and SYSIGW01 = 1 + 2 = 3).
