Host options and settings for IBMXIV systems

You must use specific settings to identify Lenovo Storage V7000clustered systems as hosts to IBM® XIV® Storage System systems.

An XIV® Nextra™ host is a single WWPN, so one XIV Nextra host must be defined for each Lenovo Storage V7000 node port in the clustered system. An XIV Nextra host is considered to be a single SCSI initiator. Up to 256 XIV Nextra hosts can be presented to each port. Each Lenovo Storage V7000 host object that is associated with the XIV Nextra system must be associated with the same XIV Nextra LUN map because each LU can only be in a single map.

An IBM XIV Storage System Type Number 2810 host can consist of more than one WWPN. Configure each Lenovo Storage V7000 node as an IBM XIV Storage System Type Number 2810 host and create a cluster of IBM XIV Storage System systems that corresponds to each of the Lenovo Storage V7000 nodes in the Lenovo Storage V7000 system.

Table 1 lists the host options and settings that can be changed using the IBM XIV Storage System and XIV Nextra Storage Management GUI.

Option Data type Range IBM XIV Storage System Type Number 2810 and XIV Nextra default setting Lenovo Storage V7000 required setting Notes
Type Enum FC/iSCSI Not applicable FC The Type must be FC for Lenovo Storage V7000.
XIV Nextra map_set_special_type CLI command or IBM XIV 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 Lenovo Storage V7000 LUNs.
WWPN int64 Any Not applicable Node port For XIV Nextra, one host for each node port WWPN in the clustered system must be defined. For IBM XIV 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 XIV Nextra, each Lenovo Storage V7000 host in the XIV Nextra system must be associated with the same LUN map because each LU can be only in a single map.
