Testing enclosure connections NOTE: Once the power-on sequence for enclosures succeeds, the storage system is ready to be connected to hosts, as described in "Connecting the enclosure to data hosts" (page 31). Powering on/powering off Before powering on the enclosure for the first time: • Install all disk drives in the enclosure so the controller can identify and configure them at power-up. • Connect the cables and power cords to the enclosures as explained in the quick start instructions.
Power cord connect Figure 16 AC power supply To power on the system: 1. Obtain a suitable AC power cord for each AC power supply that will connect to a power source. 2. Plug the power cord into the power cord connector on the back of the drive enclosure (see Figure 16). Plug the other end of the power cord into the rack power source. Wait several seconds to allow the disks to spin up. Repeat this sequence for each power supply within each drive enclosure. 3.
Connect power cable to DC power supply Locate two DC power cables that are compatible with your controller enclosure. Connector pins (typical 2 places) +L +L +L +L GND -L GND -L GND -L GND -L Ring/lug connector (typical 3 places) Connector (front view) Figure 18 DC power cable featuring sectioned D-shell and lug connectors See Figure 18 and the illustration at left (in Figure 17) when performing the following steps: 1. Verify that the enclosure power switches are in the Off position. 2.
• Use the SMU to shut down both controllers, as described in the online help and HP MSA 2040 SMU Reference Guide. Proceed to step 3. • Use the command-line interface to shut down both controllers, as described in the HP MSA 2040 CLI Reference Guide. 3. Press the power switches at the back of the controller enclosure to the Off position. 4. Press the power switches at the back of each drive enclosure to the Off position.
4 Connecting hosts Host system requirements Data hosts connected to HP MSA 2040 arrays must meet requirements described herein. Depending on your system configuration, data host operating systems may require that multi-pathing is supported. If fault-tolerance is required, then multi-pathing software may be required. Host-based multi-path software should be used in any configuration where two logical paths between the host and any storage volume may exist at the same time.
The MSA 2040 SAN controller supports Fibre Channel Arbitrated Loop (public or private) or point-to-point topologies. Loop protocol can be used in a physical loop or in a direct connection between two devices. Point-to-point protocol is used to connect to a fabric switch. See the set host-parameters command within the HP MSA 2040 CLI Reference Guide for command syntax and details about connection mode parameter settings relative to supported link speeds.
TIP: Use the SMU Configuration Wizard to set iSCSI port options. Within the SMU Reference Guide, see “Configuring the system > Using the Configuration Wizard > Configuring host ports,” and scroll to iSCSI port options. Use the CLI command set host-parameters to set iSCSI port options, and use either the show host-parameters or show ports commands to view information about host ports.

• For remote replication, ensure that all ports assigned for replication are able to communicate appropriately with the remote replication system (see verify remote-link in the CLI Reference Guide for more information). • Allow two ports to perform replication. This permits the system to balance the load across those ports as I/O demands rise and fall.
Host ports and replication MSA 2040 SAN controller modules can use qualified SFP options of the same type, or they can use a combination of qualified SFP options supporting different interface protocols. If you use a combination of different protocols, then host ports 1 and 2 are set to FC (either both16 Gbit/s or both 8 Gbit/s), and host ports 3 and 4 must be set to iSCSI (either both 10GbE or both 1 Gb). Each host port can perform I/O or replication.
The diagram below shows host interface connections and replication, with I/O and replication occurring on different networks. For optimal protection, use two switches. Connect two ports from each controller module to the first switch to facilitate I/O traffic, and connect two ports from each controller module to the second switch to facilitate replication.

Updating firmware After installing the hardware and powering on the storage system components for the first time, verify that the controller modules, expansion modules, and disk drives are using the current firmware release. Using the SMU, right-click the system in the Configuration View panel, and select Tools Update > Firmware. The Update Firmware panel displays the currently installed firmware versions, and enables you to update them.
Connecting hosts
5 Connecting to the controller CLI port Device description The MSA 2040 controllers feature a command-line interface port used to cable directly to the controller and initially set IP addresses, or perform other configuration tasks. This port employs a mini-USB Type B form factor, requiring a cable that is supplied with the controller, and additional support, so that a server or other computer running a Linux or Windows operating system can recognize the controller enclosure as a connected device.
1. Locate the DVD included with your MSA 2040 storage device. 2. Insert the DVD into the drive on a Linux or Windows computer on the network that is connected to your controller enclosure. 3. Use Autorun or manually start the DVD. The MSA Device Discovery Tool will run. 4. Follow the instructions to discover the IP addresses of the controller or controllers. Record these IP addresses so that you can specify them whenever you manage the controllers using the SMU or the command-line interface.

6 Basic operation Verify that you have completed the sequential “Installation Checklist” instructions in Table 1 (page 19). Once you have successfully completed steps 1 through 8 therein, you can access the management interface using your web browser, to complete the system setup. Accessing the SMU Upon completing the hardware installation, you can access the web-based management interface—SMU (Storage Management Utility)—from the controller module to monitor and manage the storage system.
Basic operation
7 Troubleshooting USB CLI port connection MSA 2040 controllers feature a CLI port employing a mini-USB Type B form factor. If you encounter problems communicating with the port after cabling your computer to the USB device, you may need to either download a device driver (Windows), or set appropriate parameters via an operating system command (Linux). See "Connecting to the controller CLI port" (page 43) for more information.
Use the CLI As an alternative to using the SMU, you can run the show system command in the CLI to view the health of the system and its components. If any component has a problem, the system health will be Degraded, Fault, or Unknown, and those components will be listed as Unhealthy Components. Follow the recommended actions in the component Health Recommendations field to resolve the problem.
• Informational. A configuration or state change occurred, or a problem occurred that the system corrected. No immediate action is required. See the HP MSA 2040 Event Descriptions Reference Guide for information about specific events, located at your HP MSA 2040 manuals page: http://www.hp.com/support/msa2040/Manuals. The event logs record all system events. It is very important to review the logs, not only to identify the fault, but also to search for events that might have caused the fault to occur.
The Number of Reads and Number of Writes outputs show the number of these operations that have occurred since the statistic was last reset, or since the controller was restarted. 2. Run the show vdisk-statistics command a second time. This provides you a specific window of time (the interval between requesting the statistics) to determine if data is being written to or read from the disk. 3. If any reads or writes occur during this interval, a host is still reading from or writing to this vdisk.
Is the enclosure rear panel Fault/Service Required LED amber? Answer Possible reasons Actions No System functioning properly. No action required. Yes (blinking) One of the following errors occurred: • Table 6 • • • Hardware-controlled power-up error Cache flush error Cache self-refresh error • • Restart this controller from the other controller using the SMU or the CLI. If the above action does not resolve the fault, remove the controller and reinsert it.
Is a connected host port Host Link Status LED off? Answer Possible reasons Actions No System functioning properly. No action required. (see Link LED note: page 79) Yes The link is down. • • • • • • • • Table 9 Check cable connections and reseat if necessary. Inspect cables for damage. Replace cable if necessary. Swap cables to determine if fault is caused by a defective cable. Replace cable if necessary. Verify that the switch, if any, is operating properly. If possible, test with another port.
Is the power supply Input Power Source LED off? Answer Possible reasons Actions No System functioning properly. No action required. Yes The power supply is not receiving adequate power. • • • • Verify that the power cord is properly connected and check the power source to which it connects. Check that the power supply FRU is firmly locked into position. In the SMU, check the event log for specific information regarding the fault; follow any Recommended Actions.
If the controller has failed or does not start, is the Cache Status LED on/blinking? Answer Actions No, the Cache LED status is off, and the controller does not boot. If valid data is thought to be in Flash, see Transporting cache; otherwise, replace the controller module. No, the Cache Status LED is off, and the controller boots. The system has flushed data to disks. If the problem persists, replace the controller module. Yes, at a strobe 1:10 rate - 1 Hz, and the controller does not boot.
3. Check the Cache Status LED to verify that the controller cached data is flushed to the disk drives. • Solid – Cache contains data yet to be written to the disk. • Blinking – Cache data is being written to CompactFlash. • Flashing at 1/10 second on and 9/10 second off – Cache is being refreshed by the supercapacitor. • Off – Cache is clean (no unwritten data). 4. Remove the SFP and host cable and inspect for damage. 5. Reseat the SFP and host cable.
• Flashing at 1/10 second on and 9/10 second off – Cache is being refreshed by the supercapacitor. • Off – Cache is clean (no unwritten data). 4. Reseat the host cable and inspect for damage. Is the host link status LED on? • Yes – Monitor the status to ensure that there is no intermittent error present. If the fault occurs again, clean the connections to ensure that a dirty connector is not interfering with the data path. • No – Proceed to the next step. 5.
• No – Proceed to the next step. 5. Move the expansion cable to a port on the controller enclosure with a known good link status. This step isolates the problem to the expansion cable or to the controller module expansion port. Is the expansion port status LED on? • Yes – You now know that the expansion cable is good. Return the cable to the original port. If the expansion port status LED remains off, you have isolated the fault to the controller module expansion port. Replace the controller module.
secondary systems. Once setup is successfully completed, you can initiate replication from the SMU or the CLI. • For descriptions of replication-related events, see the Event Descriptions Reference Guide. Diagnostic steps for replication setup Can you successfully use the Remote Snap feature? Answer Possible reasons Actions Yes System functioning properly. No action required. No Remote Snap is not licensed on each controller enclosure used for replication.
Can you create a replication set? Answer Possible reasons Actions Yes System functioning properly. No action required. No Selected link type or port-to-link connections are incorrect. • Remote Replication mode: In the Configuration View panel in the SMU, right-click the remote system, and select Tools > Check Remote System Link. Click Check Links to verify correct link type and remote host port-to-link connections.
Can you replicate a volume? Answer Possible reasons Actions Yes System functioning properly. No action required. No Remote Snap is not licensed on each controller enclosure used for replication. See actions described in "Can you successfully use the Remote Snap feature?" (page 62). No Nonexistent replication set. • • • No Network error occurred during in-progress replication. • • • No Communication link is down. Determine existence of primary or secondary volumes.
Resolving voltage and temperature warnings 1. Check that all of the fans are working by making sure the Voltage/Fan Fault/Service Required LED on each power supply is off, or by using the SMU to check enclosure health status. In the Configuration View panel, right-click the enclosure and select View > Overview to view the health status of the enclosure and its components.
Temperature sensors Extreme high and low temperatures can cause significant damage if they go unnoticed. Each controller module has six temperature sensors. Of these, if the CPU or FPGA (Field Programmable Gate Array) temperature reaches a shutdown value, the controller module is automatically shut down. Each power supply has one temperature sensor. When a temperature fault is reported, it must be remedied as quickly as possible to avoid system damage.

between the host and the chip on the controller, the controller is not communicating with the chip. To reset the LED, the controller must be properly power-cycled [see "Powering on/powering off" (page 27)]. Cache Status LED details If the LED is blinking evenly, a cache flush is in progress. When a controller module loses power and write cache contains data that has not been written to disk, the supercapacitor pack provides backup power to flush (copy) data from write cache to CompactFlash memory.
NOTE: See "Powering on/powering off" (page 27) for information on power-cycling enclosures. MSA 2040 6 Gb 3.5" 12-drive enclosure—rear panel layout MSA 2040 controllers support the MSA 2040 6 Gb 3.5" 12-drive enclosure.

B Environmental requirements and specifications Safety requirements Install the system in accordance with the local safety codes and regulations at the facility site. Follow all cautions and instructions marked on the equipment. Also, refer to the documentation included with your product ship kit. Site requirements and guidelines The following sections provide requirements and guidelines that you must address when preparing your site for the installation.
• Site wiring must include an earth ground connection to the DC power source. Grounding must comply with local, national, or other applicable government codes and regulations. • Power circuits and associated circuit breakers must provide sufficient power and overload protection. Weight and placement guidelines Refer to "Physical requirements" (page 85) for detailed size and weight specifications. • The weight of an enclosure depends on the number and type of modules installed.
modules with an Internet Protocol (IP) address, you then use a remote management host on an Ethernet network to configure, manage, and monitor. NOTE: Connections to this device must be made with shielded cables–grounded at both ends–with metallic RFI/EMI connector hoods, in order to maintain compliance with NEBS and FCC Rules and Regulations.
Environmental requirements NOTE: For operating and non-operating environmental technical specifications, see QuickSpecs: http://www.hp.com/support/msa2040/QuickSpecs. Electrical requirements Site wiring and power requirements Each enclosure has two power supply modules for redundancy. If full redundancy is required, use a separate power source for each module.
C Electrostatic discharge Preventing electrostatic discharge To prevent damaging the system, be aware of the precautions you need to follow when setting up the system or handling parts. A discharge of static electricity from a finger or other conductor may damage system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device. To prevent electrostatic damage: • Avoid hand contact by transporting and storing products in static-safe containers.

D SFP option for host ports Locate the SFP transceivers Locate the qualified SFP option for your Converged Network Controller module within your product ship kit. You can also obtain the part numbers using QuickSpecs. NOTE: See the “HP MSA 2040 SAN Storage array and iSCSI SFPs Read This First” document for important information pertaining to iSCSI SFPs. The SFP transceiver (SFP) should look similar to the generic SFP shown in the figure below.
The installed SFP should look similar to the position shown in the right detail view. 6. When ready to attach to the host, obtain and connect a qualified cable option to the duplex jack at the end of the SFP connector. NOTE: To remove an SFP module, perform the above steps in reverse order. Verify component operation View the host port Link Status/Link Activity LED on the controller module face plate.
