Hitachi Universal Storage Platform V TrueCopy for IBM z/OS User’s Guide
WARNING: Before changing a fibre-channel port to an initiator port,
disconnect the port from the host, release all affected TrueCopy for z/OS pairs,
delete all paths from the port to the MCU (if RCU target), and then remove all
channel paths to the port.
WARNING: Before changing a fibre-channel port from initiator to target or
RCU target, release all affected TrueCopy for z/OS pairs, delete all paths from
the initiator port to the RCU, and then delete the RCU from the MCU.
Caution: Limit the number of hosts connected to an RCU target port to 128 or
fewer to avoid mistaken disconnection. If more than 128 hosts are connected
to an ordinary target, some hosts may be disconnected after changing the
type from target to RCU target.
