HP 3PAR Solaris Implementation Guide

NOTE: HP recommends host persona 2 (Generic-ALUA) for Solaris 11 and host persona 1
(Generic) for Solaris 8, 9, and 10 (all supported MU levels). Host persona 1 for Solaris 10
is required to enable Host Explorer functionality. Host persona 1 enables 3PAR Host Explorer,
which requires the SESLun element of Host persona 1. Newly exported VLUNs can be seen
in format by issuing devfsadm -i iscsi. To register the data VLUN 254 on Solaris
format, a host reboot is required.
NOTE: You must configure the HP 3PAR StoreServ Storage iSCSI target port(s) and establish
an iSCSI Initiator connection/session with the iSCSI target port from the host to be able to
create a host definition entry. For details, see “Configuring the Host for an iSCSI Connection”
(page 41).
3. Verify that the host entry has been created.
# showhost
Id Name Persona ---------------WWN/iSCSI_Name--------------- Port
1 solaris-host-01 Generic iqn.1986-03.com.sun:01:ba7a38f0ffff.4b798940 0:3:1
iqn.1986-03.com.sun:01:ba7a38f0ffff.4b798940 1:3:1
The showhost -d command provides more details on the connection.
Configuring CHAP Authentication (Optional)
Solaris supports Challenge-Handshake Authentication Protocol (CHAP) for higher security
connectivity. CHAP uses the notion of challenge and response and has two authentication types
supported by the HP 3PAR OS.
• Unidirectional or Host CHAP authentication is used when the HP 3PAR StoreServ Storage
iSCSI target port authenticates the iSCSI Host initiator when it tries to connect.
• Bidirectional (Mutual) CHAP authentication adds a second level of security where both the
iSCSI target and host authenticate each other when the host tries to connect to the target.
• The CHAP secret for init CHAP and the target CHAP must be different.
Enabling Unidirectional (Host) CHAP
To set the host CHAP authentication after an iSCSI host definition has been created on the HP 3PAR
StoreServ Storage, use the HP 3PAR OS CLI sethost initchap command to set the host CHAP
secret.
Example:
a. Verify that a host definition has been created.
