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

Requirement 1

To each server, you can register either host groups or iSCSI targets. To manage a host that has both Fibre Channel HBAs and iSCSI HBAs as a server, create a 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 the same host group (or iSCSI target) to multiple servers. 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 host groups (or iSCSI targets) corresponding to the same port to the same server. 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 a maximum of 32 host WWNs or iSCSI names to a single server. To manage as a server a host that has more than 32 HBAs, create multiple servers for that host.

Requirement 5

You cannot register to a server a host group that has an path to an 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 a host group (or an iSCSI target) to a server, change the LU security setting to ON.

Requirement 7

You cannot register a host group (or an iSCSI target) whose ID is 0 to a server. Use a host group (or iSCSI target) whose ID is not 0.
