3. On the Host Details page, enter a name for the host and select the operating system. 4. On the Host Protocol page, select either iSCSI or FC. Review the prerequisites for the host connections. 5. On the Host Initiators page, select an initiator from the autodiscovered initiators list or create your own. To add an initiator, click Add Initiators and enter the IQN identifier. 6. On the Summary page, review the host connection details, and click Add Host. Add a host group Prerequisites The following rules apply to host groups: • A host can belong to one host group only. • If the host has mapped volumes, you cannot add a host to a host group. • You cannot add a host to a host group that uses a different protocol. • A volume can belong to multiple host groups. • A host group can be associated with one initiator. • When you remove a host from a host group, the associated volumes get detached from the host, and the host becomes a stand-alone host. Obtain the following information: • A host group name that you can use as a lookup later. • Name of the hosts you want to include in the host group. Steps 1. Under Compute, select Hosts & Host Groups. 2. Click Add Host Group. 3. On the Add Host Group page: • Enter a name for the host group. • Select the protocol. • Select the hosts to add to the group. 4. Click Create. Configure CHAP authentication Challenge Handshake Authentication Protocol (CHAP) authenticates iSCSI initiators (hosts) and targets (volumes and snapshots) to expose iSCSI storage while ensuring a secure, standard storage protocol. About this task Without CHAP authentication, any host that is connected to the same IP network as the system iSCSI ports can read from and write to the system. If your system is on a public network, it is strongly recommended that you use CHAP authentication. NOTE: If you plan to use CHAP authentication, you must set up and enable CHAP authentication before preparing volumes to receive data. If you prepare drives to receive data before you set up and enable CHAP authentication, you could lose access to the volumes. For more information about CHAP authentication, including the benefits that it provides and details about implementation types, see the context-sensitive help entry in PowerStore Manager. For in-depth information about how this feature works, see the PowerStore Security Configuration Guide. Steps 1. Select the Settings icon, and then select CHAP in the Security section. 2. Enable CHAP authentication. Additional configuration details are displayed. 3. Select the type of CHAP implementation to use and click Apply. Hosts and host group configurations 13

•
A volume can belong to multiple host groups.
•
A host group can be associated with one initiator.
•
When you remove a host from a host group, the associated volumes get detached from the host, and the host becomes a stand-alone
host.
Obtain the following information:
•
A host group name that you can use as a lookup later.
•

Configure CHAP authentication
Challenge Handshake Authentication Protocol (CHAP) authenticates iSCSI initiators (hosts) and targets (volumes and snapshots) to
expose iSCSI storage while ensuring a secure, standard storage protocol.
About this task
Without CHAP authentication, any host that is connected to the same IP network as the system iSCSI ports can read from and write to
the system. If your system is on a public network, it is strongly recommended that you use CHAP authentication.
NOTE:
If you plan to use CHAP authentication, you must set up and enable CHAP authentication before preparing
volumes to receive data. If you prepare drives to receive data before you set up and enable CHAP authentication, you
could lose access to the volumes.
For more information about CHAP authentication, including the benefits that it provides and details about implementation types, see the
context-sensitive help entry in PowerStore Manager.

PowerStore Security Configuration Guide
