Configuring Chap - HP P2000 Reference Manual

To modify an explicit mapping
1. In the Maps for Host table, select the Explicit mapping to change.
2. Set the LUN and select the ports and access type.
3. Click Apply. A message specifies whether the change succeeded or failed.
4. Click OK. The mapping settings are updated.
To delete an explicit mapping
1. In the Maps for Host table, select the Explicit mapping to delete.
2. Clear Map.
3. Click Apply. A message specifies whether the change succeeded or failed.
4. Click OK. The mapping returns to the Default mapping.

Configuring CHAP

For iSCSI, you can use Challenge-Handshake Authentication Protocol (CHAP) to perform authentication
between the initiator and target of a login request.
To perform this identification, a database of CHAP entries must exist on each device. Each CHAP entry can
specify one name-secret pair to authenticate the initiator only (one-way CHAP) or two pairs to authenticate
both the initiator and the target (mutual CHAP). For a login request from an iSCSI host to a storage system,
the host is the initiator and the storage system is the target.
To enable or disable CHAP for all iSCSI hosts, see
To add or modify a CHAP entry
1. In the Configuration View panel, right-click Hosts or a specific host and then select Provisioning >
Configure CHAP. If any CHAP entries exist, a table shows them by node name.
2. Optionally, select an entry whose name you want to change to create a new entry. The entry's values
appear in the option fields.
3. Set the options:
• Node Name (IQN). The initiator name, typically in IQN format.
• Secret. The secret that the target uses to authenticate the initiator. The secret is case sensitive and
can include 12–16 bytes.
• Name, if mutual CHAP. Optional; for mutual CHAP only. Specifies the target name, typically in IQN
format. The name is case sensitive, can include a maximum of 223 bytes, and must differ from the
initiator name. To find a controller iSCSI port's IQN, select the controller enclosure, view the
Enclosure Overview panel
view the Target ID field.
• Secret, if mutual CHAP. Optional; for mutual CHAP only. Specifies the secret that the initiator uses to
authenticate the target. The secret is case sensitive, can include 12–16 bytes, and must differ from
the initiator secret. A storage system's secret is shared by both controllers.
4. Click Add/Modify Entry. If the task succeeds, the new or modified entry appears in the CHAP entries
table.
To delete a CHAP entry
1. In the Configuration View panel, right-click Hosts or a specific host and then select Provisioning >
Configure CHAP. If any CHAP entries exist, a table shows them by node name.
2. Select the entry to delete.
3. Click Delete Entry. If the task succeeds, the entry is removed from the CHAP entries table.
