Page description
As shown in Figure 1, the interface includes five tabs, each of which is documented in detail in a
separate section in this guide.
Figure 1 SMU display — showing the five tabs
•View—For viewing detailed configuration and status information. (For more information, see
“View”onpage19”.)
•Configure—For initially configuring a system, entering new information, or changing existing
settings. (For more information, see “Configure” on page 25.)
•Wizards—For initially configuring a simple system. (For more information, see
“Wizards” on page 69”.)
•Diagnose—For generating an XML-formatted diagnostic report. (For more information, see
“Diagnose” on page 77”.)
•Update—For updating MSA controller and module firmware. (For more information see
“Update”onpage79.)
Initial configuration methods
The SMU provides two methods to initially configure your system:
•The Wizard tab—includes the Initial System Configuration Wizard, which is the easiest and
simplest method for initially configuring the storage system. You are prompted in a logical
sequence for storage, iSCSI, logon, and management settings. The wizard then uses those settings
to configure the storage and make it available to the initiator. This configuration method is
best for single-server environments needing bulk storage, because one target is created, and is
assigned to one initiator. For information about using the wizard, see “Wizards”onpage69.
•The Configure tab—offers more flexibility than the wizard when configuring the storage.
This configuration method is best for multi-server environments that need to customize the
creation of storage LUNs and targets. For information about using the Configure tab, see
“Configure”onpage25.
14 Overview

Accessing the SMU
1. Install, connect, and apply power to the storage and other network devices, as detailed in your
system user documentation.
2. Obtain and record the IP address assigned to the primary management port (MA0). (Worksheets
may be provided with you system installation instructions.)
To determine the IP address, press the arrow buttons on the front of the array controller and scroll
through the messages until the following message is displayed on the controller LCD panel:
603 Port MA0 IP <address>
NOTE:
• If the IP address message is not displayed on the LCD panel, an IP address was not
assigned to the management port. Check the cable connections, view the module LEDs,
and read the system installation, maintenance and service, or other user documents
for troubleshooting information.
• If necessary, you can change the management IP address through
the controller LCD panel management menu. For more information, see
“Changing the management port IP address through the MSA1510i controller display panel”onpage16.
3. From a server or workstation with access to the storage device, open your Web browser and enter
the address obtained in Step 2.
For example: http://10.10.1.254
NOTE:
For additional security (at a reduced performance level), access the SMU using the secure
mode. For example: https://10.10.1.254
4. Enter the username and password. Default settings are:
•Username:root
•Password:root
HP Storage Management Utility user guide 15

5. Wait a few moments for the utility to load.
NOTE:
When accessing the SMU for the first time, a window is displayed requiring input of a
user-defined username and password.
6. One of the following happens:
• If key components of the system are unconfigured,aprompttogototheWizardtabis
displayed. (For more information, see “Wizards”onpage69.)
• If the system is partially configured, the Configure tab is displayed. (For more information,
see “Configure”onpage25.)
•Ifthesystemisconfigured, the View tab is displayed. (For more information, see
“Diagnose” on page 77.)
Changing the management port IP address through the
MSA1510i controller display panel
When the MSA1510i is initially installed and powered on, an IP address is automatically assigned to
the primary management port (usually MA0). Depending on your network configuration,thisdefaultIP
address may not be accessible by the network servers.
To change the IP address of the MSA1510i management port to be in the same LAN segment as the
network servers, do the following:
1. Access the controller LCD panel management menu. Press the right (>) navigation button on the
front of the active controller (usually the front-right controller.) Network Settings should be displayed
and blinking.
LCD panel navigation buttons work as follows:
Navigation button In the menu Within a menu option
Right (>) Select a blinking menu option. When changing IP address
settings, move to the next digit.
Up/Down (^/v) Scroll through the menu options. Change/Toggle a setting.
Left (<) Not applicable. Accept the displayed setting and
return to the initial management
menu display.
16 Over view

2. Disable DHCP.
a. With Network Settings displayed and blinking, press >to select it.
b. Press ^or vuntil DHCP Enabled is displayed and blinking, and then press >to select it.
c. Press ^or vto change the setting to No.
d. Press <to accept the new setting and return to the initial management menu display.
3. Change the IP address.
a. With Network Settings displayed and blinking, press >to select it.
b. Press ^or vuntil IP Address is displayed and blinking, and then press >to select it.
c. Press ^or vto scroll through and select the value for each digit of the IP address.
d. After entering all digits of the new IP address, press <to accept the new setting and return to the
initial management menu display.
4. Verify and, if necessary, change the Subnet Mask, Default Gateway, Primary DNS, Secondary DNS,
and VLAN ID using procedures similar to those outlined in step 3, but pressing ^ or v to navigate
to the desired menu option.
5. After all changes are entered, exit the management menu.
Press vuntil Exit is displayed and blinking, and then press >.
The LCD panel returns to the display mode.
6. Verify that the IP address was entered correctly by pressing ^or vuntil the Port #MA0 IP message
is displayed.
7. Verify that the server can locate the MSA1510i by opening a command prompt window and using
the ping command.
Best practices
•Go to the HP storage website: http://www.hp.com/storage foryourarraycontroller.Product
websites are updated to include the latest:
• Hardware, firmware, and driver compatibility information.
•Firmwareand/orsoftware.
•System
documentation.
•Use provided installation documents to gather items required for your installation, learn about the
installation process, and physically install devices.
•Record information about your system in provided checklists and worksheets. This information
is needed when configuring the storage, entering connection information, and setting up
multipathing; and for future configuration changes, reference, and troubleshooting purposes.
•Sign up with Subscriber's Choice to receive e-mail notifications and alerts about your HP devices:
http://www.hp.com/go/e-updates.
•Separate management traffic from iSCSI storage traffic. Provide separate physical LANs or create
Virtual LANs (VLANs) to segment the traffic.
•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.
•Ensure the availability of the storage:
•Pro
vide redundant power sources—Plug the two power supplies on the device into separate
Uninterruptible Power Supplies (UPS) on separate sources of power. If you have only one UPS,
maintain separate power paths by plugging one power supply to the UPS on one power
source and plug the other power supply to a separate power source.
•Pr
ovide redundant data paths—Include two separate and isolated iSCSI storage networks
and the associated hardware (switches, MSA controllers, etc.) and software components
HP Storage Management Utility user guide 17

(MPIO multipathing software, etc.) in the configuration. Configure targets using portals
on each controller.
• Create fault-tolerant logical storage units—Create LUNs using fault-tolerant RAID levels and
striping methods.
•When assigning system names and aliases, use only the following characters:
• Uppercase alpha characters (A-Z)
• Lowercase alpha characters (a-z)
•Numericcharacters(0-9)
• Special characters (! # = ( ) ‘ ; , . and space)
•When accessing the SMU, expand the browser to full screen or a minimum size of 1024 x 768
pixels. Other settings may distort the display or cause items to not display.
•When planning and configuring logical drives:
• Optimize performance and redundancy by striping the drives in the array across separate
storage enclosures on different SCSI buses, especially in mirrored environments using
RAID 1+0.
• Set the drive rebuild priority to high to minimize exposure during a drive failure.
• Customize the RAID level and striping method to the type of data that will be stored on the
logical drive.
NOTE:
Depending on the number of physical hard drives included in a storage unit, the SMU may suggest
RAID 6 (ADG) as the default RAID level, which offers a high level of fault tolerance and usable disk
capacity, but at a significant cost to I/O performance. For comparable fault tolerance but higher
performance, consider using RAID 1+0 when fault tolerance is desired and performance is more
important than usable capacity. Reserve RAID 6 (ADG) for situations when fault tolerance is desired,
but usable capacity is more important than performance.
•After configuring the storage, remember to:
• Verify that each initiator has been granted access to the target.
• Control access to the storage through the use of VLANs, CHAP authentication, and ACLs.
•Draw physical and logical diagrams of your network:
• Hardware/device diagram—Physical layout of the entire network, including device names
and cabling.
• Storage diagram—Hard drive and storage system configuration, including RAID levels.
• Path/Accessibility diagram—Access information, including which devices are allowed to
communicate with each other.
