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 29). 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 13 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 13). 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 15 DC power cable featuring sectioned D-shell and lug connectors See Figure 15 and the illustration at left (in Figure 14) 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 1040 SMU Reference Guide. Proceed to step 3. • Use the command-line interface to shut down both controllers, as described in the HP MSA 1040 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 1040 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.
Fibre Channel ports are used in either of two capacities: • To connect two storage systems through a Fibre Channel switch for use of Remote Snap replication. • For attachment to FC hosts directly, or through a switch used for the FC traffic. The first usage option requires valid licensing for the Remote Snap replication feature, whereas the second option requires that the host computer supports FC and optionally, multipath I/O. TIP: Use the SMU Configuration Wizard to set FC port speed.
The first usage option requires valid licensing for the Remote Snap replication feature, whereas the second option requires that the host computer supports Ethernet, iSCSI, and optionally, multipath I/O. Connecting direct attach configurations The MSA 1040 controller enclosures support up to four direct-connect server connections, two per controller module. Connect appropriate cables from the server HBAs to the controller host ports as described below, and shown in the following illustrations.
Two servers/one HBA per server/dual path MSA 1040 Server 1 Server 2 6Gb/s 6Gb/s Figure 18 Connecting hosts: direct attach—two servers/one HBA per server/dual path Connecting switch attach configurations Dual controller configuration Two servers/two switches MSA 1040 Server 1 Server 2 Switch A Switch B 6Gb/s 6Gb/s Figure 19 Connecting hosts: switch attach—two servers/two switches Connecting remote management hosts The management host directly manages systems out-of-band over an Ethernet network.
replication set need only be connected to the primary system. If the primary system goes offline, a connected server can access the replicated data from the secondary system. Replication configuration possibilities are many, and can be cabled—in switch attach fashion—to support MSA 1040 systems on the same network, or on different networks.
Once the MSA 1040 systems are physically cabled, see the SMU Reference Guide or online help for information about configuring, provisioning, and using the optional Remote Snap feature. NOTE: See the HP MSA 1040 SMU Reference Guide for more information about using Remote Snap to perform replication tasks. The SMU Replication Setup Wizard guides you through replication setup. Host ports and replication MSA 1040 controller modules use qualified SFP options of the same type (FC or iSCSI).
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 one port from each controller module to the first switch to facilitate I/O traffic, and connect one port from each controller module to the second switch to facilitate replication.
IMPORTANT: See the “About firmware update” and “Updating firmware” topics within the MSA 1040 SMU Reference Guide before performing a firmware update. NOTE: To locate and download the latest software and firmware updates for your product, go to http://www.hp.com/support.
5 Connecting to the controller CLI port Device description The MSA 1040 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.
NOTE: For more information, see Using the Configuration Wizard > Configuring network ports within the HP MSA 1040 SMU Reference Guide. Setting network port IP addresses using the CLI port and cable You can set network port IP addresses manually using the command-line interface port and cable. If you have not done so already, you need to enable your system for using the command-line interface port [also see "Using the CLI port and cable—known issues on Windows" (page 40)].
• Linux customers should enter the command syntax provided in "Preparing a Linux computer before cabling to the CLI port" (page 37). • Windows customers should locate the downloaded device driver described in "Downloading a device driver for Windows computers" (page 37), and follow the instructions provided for proper installation. 4.
Network parameters, including the IP address, subnet mask, and gateway address are displayed for each controller. 9. Use the ping command to verify network connectivity. For example: # ping 192.168.0.1 (gateway) Info: Pinging 192.168.0.1 with 4 packets. Success: Command completed successfully. - The remote computer responded with 4 packets. 10.
2. Connect using the USB COM port and Detect Carrier Loss option. a. Select Connect To > Connect using: > pick a COM port from the list. b. Select the Detect Carrier Loss check box. The Device Manager page should show “Ports (COM & LPT)” with an entry entitled “Disk Array USB Port (COMn)”—where n is your system’s COM port number. 3. Set network port IP addresses using the CLI (see procedure on page 38). To restore a hung connection when the MC is restarted (any supported terminal emulator): 1.

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 1040 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 37) 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 Event Descriptions Reference Guide for information about specific events, located at your HP MSA 1040 manuals page: http://www.hp.com/support/msa1040/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.
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. Continue to stop IOPS from hosts, and repeat step 1 until the Number of Reads and Number of Writes statistics are zero. See the HP MSA 1040 CLI Reference Guide for additional information, at your HP MSA 1040 manuals page: http://www.hp.

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.
1. Halt all I/O to the storage system as described in "Stopping I/O" (page 47). 2. Check the host link status/link activity LED. If there is activity, halt all applications that access the storage system. 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.
NOTE: Do not perform more than one step at a time. Changing more than one variable at a time can complicate the troubleshooting process. 1. Halt all I/O to the storage system as described in "Stopping I/O" (page 47). 2. Check the host activity LED. If there is activity, halt all applications that access the storage system. 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.
Replication setup and verification After storage systems and hosts are cabled for replication, you can use the Replication Setup Wizard in the SMU to prepare to use the Remote Snap feature. Optionally, you can use telnet to access the IP address of the controller module and access the Remote Snap feature using the CLI.
