PPRC specifications, restrictions
Most Cnt Ac-S Z operations can be performed using PPRC TSO or ICKDSF PPRCOPY commands
from the host system console. All XP P9500 storage systems support IBM PPRC host software
functions.
Continuous Access Synchronous Z operations performed with PPRC
Using PPRC commands, you can perform the following operations:
• Create, suspend, resynchronize, and delete Cnt Ac-S Z pairs.
• Suspend, resynchronize, and delete Cnt Ac-S Z consistency groups.
• Establish and delete data paths.
• View path and pair status.
The following applies when using PPRC commands:
• The XP P9500 is capable of automatically configuring a Fibre Channel port as an initiator or
RCU target port, if required, in response to the TSO CESTPATH and CDELPATH commands.
Initiator and RCU target ports are required for sending and receiving data to and from the
main and remote system. System option mode 114 must be enabled for automatic port
configuration in response to PPRC commands.
The XP P9500 makes sure that the specified main system port is offline to the host, and
automatically configures it as an initiator port if required. Similarly, the corresponding remote
system port is configured as an RCU target port when required.
When the CDELPATH command is issued, Cnt Ac-S Z logical paths are removed. If there are
no more Cnt Ac-S Z logical paths on the port, the port is automatically changed from initiator
port to RCU target port.
• Concerning the Fibre Channel interface, do not use the CESTPATH and CDELPATH commands
when using LUN Manager’s SCSI path definition function. Fibre Channel ports must be
configured as initiator or RCU target ports before the CESTPATH and CDELPATH commands
are issued.
NOTE: Ensure that the relevant paths are offline before issuing the CESTPATH command.
The add path operation fails if active logical paths exist, because the port attribute cannot be
changed.
Continuous Access Synchronous Z options not supported with PPRC
The following Cnt Ac-S Z options cannot be changed using PPRC. Use Remote Web Console to
change these options:
