4.5.3 Modify Host Response
This function modifies host response settings.
For more details on setting the host response parameters, refer to "FUJITSU Storage ETERNUS DX Configuration
Guide -Server Connection-" for each OS type.
• The server may need to be rebooted after host response parameters are changed. Refer to "Requirements
for changing parameters" (page 475) for details.
• If an appropriate host response is not configured to the host affinity, the path may not be switched
correctly or the volume may not be recognized correctly.
• When customizing the host response, make sure to understand the setting parameters and create the
host response with careful attention.
• The recommended pattern and the default setting of the host response cannot be modified.
• When ALUA is set for the volume, ALUA is given priority over the "Asymmetric / Symmetric Logical Unit
Access" setting that is specified in this function. Refer to "3.17 Set ALUA" (page 323)
for details.
• The LUNs that can be recognized from the host are determined by the "LUN Addressing" settings and the
"LUN Expand Mode (Peripheral Device Addressing)" settings for the host response. When changing a host
response that is already allocated to a host group with the host affinity setting or a host with the host
affinity setting, check the LUN setting state. If LUNs that are LUN#256 onward are used, the recognizable
LUN setting cannot be changed to "256 LUN" (*1). Refer to "Host responses and recognizable LUNs" (page
818) for details.
*1: "Peripheral device addressing (Default)" is specified for LUN addressing and "Disable (Default)" is selected for
the LUN Expand Mode (Peripheral Device Addressing).
