Communication Modes - Hitachi AMS 2100 Hardware Manual

•
The following are notes regarding the above illustration:
1. The array uses 2000/tcp and 28355/tcp to communicate with Navigator
2. If the array can communicate with the computer on which Navigator
2 is installed directly but not through the router, the router may have
blocked ports. Set the router so that two-way communication to ports is
allowed.
2. The computer in which Navigator 2 is installed (Computer A) uses
23015/tcp and 1099/tcp to communicate with the computer to the host
(Computer B). When the computer on which Navigator 2 is installed can
communicate if connected directly but cannot communicate through the
router, the router may have blocked ports. Set the router so that the
two-way communication to ports is allowed.
3. The IPv6 multicast of the link local scope is used for the search array by
the IPv6 address. When performing the search array, set up the array
and the computer in which Hitachi Storage Navigator Modular 2 is
installed in the same link.
4. When two or more LAN cards are inserted in the computer to install
Navigator 2 and each LAN is another segment, it can only access from
the LAN card side specified by the installer.

Communication modes

When the communication settings between the array and the host and/or
management console are not the same, they may not be able to
communicate with each other. The communication mode for the array is set
to "Auto" by default. Therefore, Hitachi Data Systems recommends that
you set the host and any other storage devices on the LAN to Auto.
