12.1.3 ERM support statements
The use of DS4000 and DS5000 Enhanced Remote Mirroring with IBM i as a client of VIOS is
supported as outlined in this section. Note that to implement and use this solution, multiple
manual steps on the DS4000 or DS5000 storage subsystem, in VIOS and in IBM i are
required. Currently, no toolkit that automates this solution exists and it is not part of IBM
PowerHA for IBM i. The components of the solution – DS4000 or DS5000 ERM, VIOS and IBM i
– must be managed separately and require the corresponding skill set. Also note that support for
this solution will be provided by multiple IBM support organization and not solely by the IBM i
Support Center.
IBM PowerHA for IBM i is also supported for IBM i as a client of VIOS. PowerHA for IBM i
provides an automated, IBM i-driven replication solution that allows clients to leverage their
existing IBM i skills. PowerHA for IBM i is supported by the IBM i Support Center. For more
