Chapter 2 Configuring Your System for the First Time 45
■
iSNS Address – Specifies the IP address of an iSNS server. The default address
is all zeroes.
■
Alternate iSNS Address – Optional. Specifies the IP address of an alternate iSNS
server, which can be on a different subnet. The default address is all zeroes.
Settings that can differ for each port are:
■
IP Address – IP address for a specific port. The system uses port 0 of each
controller as one failover pair, and port 1 of each controller as a second failover
pair. Therefore, port 0 of each controller must be in the same subnet, and port 1
of each controller should be in a second subnet. For example:
■
Controller A port 0: 10.10.10.100
■
Controller A port 1: 10.11.10.120
■
Controller B port 0: 10.10.10.110
■
Controller B port 1: 10.11.10.130
■
IP Mask – IP subnet mask for a specific port. The default is 255.255.255.0.
■
Gateway – Gateway IP address for a specific port. The default is 0.0.0.0.
Caution – Changing IP settings can cause data hosts to lose access to the storage
system.
To configure host ports:
1. Select Manage > General Config > Host Port Configuration.
2. Set the common and port-specific options.
3. Click Update Host Port Configuration.
Configuring iSCSI Login Authentication
You can use Challenge-Handshake Authentication Protocol (CHAP) to perform
authentication between the originator (initiator) and recipient (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
originator only (one-way CHAP) or two pairs to authenticate both the originator and
the recipient (mutual CHAP). For a login request from an iSCSI host to a storage
system, the host is the originator and the storage system is the recipient.
You can enable or disable CHAP on the iSCSI Host Port Configuration page; see
“Configuring iSCSI Host Ports” on page 44.
