In a multiple DFSMShsm host environment, you must allocate unique PDOX and PDOY data set names for each host if the PDA log data sets are cataloged in a shared catalog. Placing the PDA log data sets on a volume managed by another processor can lead to degraded performance or a lockout. Because the PDA log data sets cannot be shared among hosts, you should:

• Catalog the PDA log data sets.
• Allocate two PDA log data sets on the same volume with data set names of qualifier.Hx.HSMPDOX and qualifier.Hx.HSMPDOY. Substitute the DFSMShsm authorized-user identification for qualifier and substitute a unique DFSMShsm host identifier for x. These substitutions make the PDA log data set names unique and identifiable with the host. Example: If the host identification is A, the PDA log data set names could be:
  • qualifier.HA.HSMPDOX
  • qualifier.HA.HSMPDOY
