Requirements for managing host groups (or iSCSI targets) from a server

Requirement 1

You can register, in one server, either host groups or iSCSI targets. To manage a host with both Fibre Channel HBAs and iSCSI HBAs as a server, create one server for the Fibre Channel HBAs and another server for the iSCSI HBAs. (For details, see requirement 1 in the figure that follows.)

Requirement 2

You cannot register, in multiple servers, the same host group (or iSCSI target). In a cluster configuration, group all the servers (nodes) composing the cluster, and manage them as one server. Manage each host group (or iSCSI target) by registering it to a single server. (For details, see requirement 2 in the figure that follows.)

Requirement 3

You cannot register, in the same server, host groups (or iSCSI targets) corresponding to the same port. If a port has multiple host groups (or iSCSI targets), create a server for each host group (or iSCSI target). (For details, see requirement 3 in the figure that follows.)

Requirement 4

You can register, in a server, a maximum of 32 host WWNs or iSCSI names. To manage a host that has more than 32 HBAs as a server, create multiple servers for that host.

Requirement 5

You cannot register, in a server, a host group that has a path to a volume that is not a Dynamic Provision, Dynamic Tiering, or Active Flash LDEV. (For details, see requirement 5 in the figure that follows.)

Requirement 6

If you register, in a server, a host group (or an iSCSI target), change the LU security setting to ON.

Requirement 7

You cannot register, in a server, a host group (or an iSCSI target) with an ID of 0. Use a host group (or iSCSI target) with an ID other than 0.

Requirement 8

You cannot register, in a server, a host group (or iSCSI target) that is associated with a virtual storage machine.

Requirement 9

You cannot register, in a server, the host group of a port whose action mode is NVMe.
