• When deleting iSCSI Host information during operation, stop access
from the host corresponding to the iSCSI Host information. To set a new
iSCSI Host information, it is not necessary to stop the host access.
• The Host-Affinity Function can be used if the [Af f i n i t y M o d e ] o f t h e t a r g e t
iSCSI-CA Port is [ON (Enabled)].
• If a Host Response is deleted using the [Set Host Response] function,
the Host Response of each iSCSI Host information associated with the
deleted Host Response is changed to [Host Response No.: Default].
• When Resource Domains are registered in the ETERNUS DX400/
DX8000 series, Resource Domains to which the iSCSI Host can be
assigned differ depending on the current user account.
- When logged on using a Total Administrator account, iSCSI Hosts
can be assigned to all the Resource Domains.
- When logged on using a Resource Domain Administrator account,
iSCSI Hosts can be assigned only to the relevant Resource Domain.
• When the host and the ETERNUS DX400/DX8000 series are connected
via iSCSI-CA, there are two methods to have the host recognize the
Logical Volumes of the ETERNUS DX400/DX8000 series. One is [Set
LUN Mapping], and the other is the Host-Affinity function, which requires
[Set iSCSI Host], [Set Affinity Group], and [Allocate Host-Affinity Group].
The [Affinity Mode] of [Set CA Parameters] set i n e v e r y i S C S I - C A P o r t
determines which function to use. If [Affinity Mode] is [ON (Enabled)],
the Host-Affinity function is enabled, whereas [Set LUN Mapping] is
enabled if [Affinity Mode] is [OFF (Disabled)].
• The Host-Affinity function is a device security function for open system
servers which is supported by Fibre Channel CAs (FC-CA) and iSCSI-
CAs. Not only [Set iSCSI Host] but also [Set Affinity Group] and
[Allocate Host-Affinity Group] are required in order to use the Host-
Affinity function with iSCSI-CA.
• If appropriate Host Response is not registered in the ETERNUS DX400/
DX8000 series, register a Host Response using the [Set Host
Response] function.
• For details about Set iSCSI Host, refer to the "ETERNUS DX Disk
storage systems Server Connection Guide (iSCSI)".
