5.5.5 Connection Operation Mode
The response from the ETERNUS DX Disk storage system can be optimized by switching the setup information
of the host response for each connected server.
The server requirements of the supported functions, LUN addressing, and the method for command responses
vary depending on the connection environments such as the server OS and the driver that will be used. A
function that handles differences in server requirements is supported. This function can specify the
appropriate operation mode for the connection environment and convert host responses that respond to the
server in the ETERNUS DX Disk storage system.
The host response settings can be specified for the server or the port to which the server connects. Refer to
"User's Guide -Server Connection-" for details on the settings.
Figure 5.20 Host response (connection operation mode)
• If the host response settings are not set correctly, a volume may not be recognized or the desired
performance may not be possible. Make sure to select appropriate host response settings.
• The maximum number of volumes (number of LUNs that are set) that can be recognized by the server
varies depending on the connection operation mode of the host response settings. The volume settings
to allow each server to access the volume can be performed in the host response settings. For details on
the function, refer to "5.2.3 Host Affinity" (page 54)
