Conﬁguration b

est practices

• Maintain detailed records of your iSCSI storage network, including information about the

initiators, targets (including which LUNs are mapped to the targets), IP address assignments, and

portals and po

rtal groups. Be sure to note which initiators are accessing which targets through

which portal groups using which IP addresses and protected by which Access Control List (ACL)

and virtual Local Area Networks (VLAN).

• When conﬁgur

ing switches, consider setting up VLANs to control access to the MSA1510i

storage targ

ets. For installation and conﬁguration instructions, see the documentation included

with the switch.

• For optimum performance from the MSA1510i, use 1000BaseT switches and qualiﬁed Category

5e (or bette

r) Ethernet cables.

• Record information about the switches that will connect to the MSA1510i using the Network switch

information worksheet in the MSA1510i installation and user guide

• Ensure that initiators and targets are on the same Layer 2 Ethernet LAN. This guarantees the

integrity of the data trafﬁc and maintains high network performance levels.

• Develop a

n IP addressing scheme for the management and data ports of the controller in slot 1 (the

front rig

ht slot), and the management and data ports of the controller in slot 2 (the front left slot).

• When conﬁguring the management and the data ports, assign the appropriate IP addresses to

the ports according to your IP addressing scheme.

• When con

ﬁguring the portals and portal groups, and mapping the LUNs to a portal group,

conﬁgur

e the mapping to manually load balance ownership of the LUNs between the portal

groups (which are assigned to the physical data ports.

Conﬁguration overview

Primar

yconﬁguration tasks

Regard

less of the management tool used or operating system environment, the following tasks must be

completed:

• Obtaining, installing, and conﬁguring initiator and multipathing software components.

•

Updating MSA controller ﬁrmware.(Ifnecessary.See“Updating MSA ﬁrmware” on page 79.)

IMPORTANT:

MSA1510i v1.32 or earlier is active/passive ﬁrmware. For active/active, you must update the ﬁrmware

to v2.0 or later. To upgrade your system to active/active, obtain the MSA1510i Support CD from the

MSA1510i Support page: h

ttp://www.hp.com/go/support. Upgrade instructions are provided on

the CD

• Conﬁ guring the MSA and its storage.

• Changing the default IP address assigned to the management port of each controller (usually MA0

and MB0) to be in the same LAN segment as the network servers. (If necessary.) (See

“Changing the management port IP address through the MSA1510i controller display panel” on page 102.)

• Creating the logical storage units (LUNs).

• Entering global controller settings, such as setting the read/write cache ratio, setting the

rebuild/expand priority, and setting the redundancy level.

• Identifying the operating system type (also called Host Mode or Proﬁle) of each initiator that will

access the MSA. This ensures that the MSA will communicate properly with that host.

• Verifying that the desired initiators are detected by the MSA.

• Creating Access Control Lists (ACLs) to isolate the storage from unauthorized access. These settings

indicate, by NIC, which LUNs the NIC can access.
