P/DAS support, restrictions

Continuous Access Synchronous Z supports the IBM P/DAS host software function. P/DAS allows
you to relocate or migrate data by redirecting all application I/Os from the M-VOL to the R-VOL
without interrupting access to the data. See the following IBM publications for important information
on the requirements and procedures for P/DAS operations: Planning for IBM Remote Copy
(SG24-2595), Advanced Copy Services (SC35-0355), DFSMS MVS V1 Remote Copy Guide and
Reference (SC35-0169).

Restrictions

The following restrictions apply to P/DAS use with Continuous Access Synchronous Z:

P/DAS through channel extenders is not supported.

P/DAS does not support CFW operations. You must stop CFW applications before performing
P/DAS operations on Continuous Access Synchronous Z volumes.

P/DAS swap option #2 (switch pair & swap) is supported for P/DAS between the P9500 and
XP12000 Disk Array/XP10000 Disk Array storage systems.
