3.7.20 Hitachi SANtinel
Hitachi SANtinel allows users to restrict LU accessibility to an open-systems host using the
host’s World Wide Name (WWN). You can set an LU to communicate only with one or more
specified WWNs, allowing you to limit access to that LU to specified open-system host(s).
This feature prevents other open-systems hosts from either seeing the secured LU or
accessing the data contained on it. The Hitachi SANtinel software for the Remote Console PC
enables you to configure Hitachi SANtinel operations on the 9900 subsystem.
Hitachi SANtinel can be activated on any installed fibre-channel port, and be turned on or
off at the port level. If you disable Hitachi SANtinel on a particular port, that LU will not be
restricted to a particular host or group of hosts. If you enable Hitachi SANtinel on a
particular port, that port will be restricted to a particular host or group of hosts. You can
assign a WWN to as many ports as you want, and you can assign more than one WWN to each
port. You can also change the WWN access for any port without disrupting the settings of
that port.
Because up to 128 WWNs can access each port and the same WWNs may go to additional
ports in the same subsystem, the Hitachi SANtinel software allows you to create LU and
WWN groups, so you can more easily manage your 9900 storage subsystem. An LU group
allows you to assign specified LUs to a single group name. A WWN group allows you to assign
up to 128 WWNs to a single group. A WWN group gives every host in the specified WWN group
access to the specified LU or group of LUs.
