You must use specific settings to identify the system as a host to IBMXIV Storage System systems.
An XIVNextra host is a single WWPN, so one XIVNextra host must be defined for each system node port in the clustered system. An XIVNextra host is considered to be a single SCSI initiator. Up to 256 XIVNextra hosts can be presented to each port. Each system host object that is associated with the XIVNextra system must be associated with the same XIVNextra LUN map because each LU can be in only a single map.
An IBMXIV Storage System Type Number 2810 host can consist of more than one WWPN. Configure each system node as an IBMXIV Storage System Type Number 2810 host and create a cluster of IBMXIV Storage System systems that corresponds to each of the system nodes.
IBMXIV Type Number 2810 and XIVNextra host options and required settings lists the host options and settings that can be changed by using the IBMXIV Storage System and XIVNextra Storage Management GUI.
| Option | Data type | Range | IBMXIV Storage System Type Number 2810 and XIVNextra default setting | System required setting | Notes |
|---|---|---|---|---|---|
| Type | Enum | FC/iSCSI | Not applicable | FC | The Type must be FC for the system. |
| XIVNextra map_set_special_type CLI command or IBMXIV Storage System Type Number 2810 special_type_set CLI command | Enum | default/hpux | default | default | This command is used by hpux hosts only. Do not use the command for the system LUNs. |
| WWPN | int64 | Any | Not applicable | Node port | For XIVNextra, one host for each node port WWPN in the clustered system must be defined. For IBMXIV Storage System, Type Number 2810 one host port for each node port WWPN in the clustered system must be defined. |
| LUN Map | String | Any | Not applicable | Any | For XIVNextra, each system host in the XIVNextra system must be associated with the same LUN map because each LU can be only in a single map. |
