The following are PPRC hardware requirements:
- Both primary and recovery site storage controls must
be of the same type (peer to peer).
- The PPRC V2 and FlashCopy® V2
features must be enabled.
- Global Mirror requires Fibre Channel Protocol (FCP) connections
between your primary and secondary subsystems. The FCP connections
can be direct or through a fibre channel switch.
- Global Mirror also requires Fibre Channel Protocol (FCP)
connections between the master storage control and each storage control
subordinate in a session.
- PPRC-capable Licensed Internal Code (LIC) must be installed on
both the primary and secondary storage subsystems. The levels
of PPRC LIC on the systems must be compatible.
- A compatible secondary volume must be available for each primary
volume you need to copy. The secondary volume must have the identical
track capacity and number of tracks per cylinder and either the same
or larger volume capacity. Any volume in a simplex state, or one
that has not completed its first pass copy, will remain in a join
pending state and will not participate in the Global Mirror session.
