5.4.6.1 Add/Change/Delete LUN Mapping
This section explains procedures to add/change/delete LUN Mapping.
Procedure
1 Click [Set LUN Mapping] under the Host Interface Management in the
[Configuration] menu.
→ The [Set LUN Mapping (Initial)] screen appears.
• If the Host Specific mode of the FC-CA Port or iSCSI-CA Port Host
Response to which LUN mappings are allocated is changed from a
mode that allows up to 512 LUNs (0x000 – 0x1FF) (*1) to a mode that
only allows up to 256 LUNs (0x000 – 0x0FF) (*2), the surplus LUN
mappings (0x100 – 0x1FF) are automatically deleted.
*1: AIX Mode (Extended Address), HP-UX Mode (SCC), or Linux/NR1000V
Mode (Extended Address)
*2: Normal Mode (Default) or AIX Mode
• When Resource Domains are registered in the ETERNUS DX400/
DX8000 series, volumes that can be mapped differ depending on the
current user account.
- When logged on using a Total Administrator account, all the volumes
that are assigned to Resource Domains can be mapped.
- When logged on using a Resource Domain Administrator account,
only the volumes that are assigned to the relevant Resource
Domain, and only the volumes that are assigned to the Shared
Resource, can be mapped.
When a host and the ETERNUS DX400/DX8000 series are connected via
FC-CA or iSCSI-CA, there are two ways for a host to recognize Logical
Volumes in the ETERNUS DX400/DX8000 series. One is [Set LUN
Mapping], and the other is the Host-Affinity function, which relies on [Set
Host World Wide Name(s)]/[Set iSCSI Host], [Set Affinity Group] and
[Allocate Host-Affinity Group]. The [Affinity Mode] setting in [Set CA
Parameters] determines which function to use for each FC-CA Port or
iSCSI-CA Port. If the [Affinity Mode] is [ON (Enabled)], the Host-Affinity
function is enabled, whereas if the [Affinity Mode] is [OFF (Disabled)], then
[Set LUN Mapping] is enabled.
