Veritas Volume Replicator software limitations

The following are software limitations in this release of Veritas Volume Replicator.

Replication in a shared environment

Currently, replication support is limited to 4-node cluster applications.

IPv6 software limitations

VVR does not support the following Internet Protocol configurations:

■ A replication configuration from an IPv4-only node to an IPv6-only node and

from an IPv6-only node to an IPv4-only node is not supported, because the

IPv6-only node has no IPv4 address configured on it and therefore VVR cannot

establish communication between the two nodes.

■ A replication configuration in which an IPv4 address is specified for the

local_host attribute of a primary RLINK and an IPv6 address is specified for

the remote_host attribute of the same RLINK.

■ A replication configuration in which an IPv6 address is specified for the

local_host attribute of a primary RLINK and an IPv4 address is specified for

the remote_host attribute of the same RLINK.
