■ Cluster configuration
When a server is duplicated in a cluster configuration and the ETERNUS DX Disk storage sys-
tem is shared by multiple servers, software to control the cluster configuration is required.
When configuring multipathing for reliability, make sure to configure a
redundant connection for the controllers of the ETERNUS DX Disk storage
system. Configure paths to connect to different controllers (CM#0 and
CM#1). Combinations of host interface port numbers (Port#0 and Port#1) in
controllers do not need to be taken into consideration.
