The system must not be run without all units in place. Operate the system with the enclosure top cover closed.9Warning To ensure protection against electric shock caused by HIGH LEAKAGE CURRENT (TOUCH CURRENT), the SGI InfiniteStorage 15000 must be connected to at least two separate and independent sources. This is to ensure a reliable earth connection.9Warning To ensure your system has warning of a power failure please disconnect the power from the power supply, by either the switch (where present) or by physically removing the power source, prior to removing the PCM from the enclosure/shelf.10Warning Do not remove covers from the PCM. Danger of electric shock inside. Return the PCM to your supplier for repair.10Warning Operation of the Enclosure with ANY modules missing will disrupt the airflow and the drives will not receive sufficient cooling. It is ESSENTIAL that all apertures are filled before operating the unit.11Recycling of Waste Electrical and Electronic Equipment (WEEE)11Important Observe all applicable safety precautions, e.g. weight restrictions, handling batteries and lasers etc., detailed in the preceding paragraphs when dismantling and disposing of this equipment11Rack System Precautions11Important SGI InfiniteStorage 15000 drive enclosures should only be installed in SGI InfiniteStorage 15000 racks. Mounting and installing these drive enclosures in any other rack is not authorized or supported by SGI.11Warning It is recommended that you do not slide more than one enclosure out of the rack at a time, to avoid danger of the rack tipping over.11ESD Precautions12Caution It is recommended that you fit and check a suitable anti-static wrist or ankle strap and observe all conventional ESD precautions when handling plug-in modules and components. Avoid contact with backplane components and module connectors, etc.12Data Security12Chapter 115Introduction151.1 Controller Features151.2 The Controller Hardware16Figure 1-1 SGI InfiniteStorage 15000 IB - Front and Rear Views171.2.1 Power Supply and Fan Modules18Figure 1-2 Fan Module (front panel)181.2.2 I/O Connectors and Status LED Indicators19Figure 1-3 I/O Ports on the Rear Panel of the Controller19Figure 1-4 Host Port LEDs20Figure 1-5 LED Status Indicators - Rear Panel of the Controller21Table 1-1 LED Indicators221.2.3 Uninterruptible Power Supply (UPS)23Chapter 225Controller Installation251. Unpack the controller system.252. If it is necessary to install the controller in the 19-inch cabinet(s), contact your service provider.253. Set up and connect the drive enclosures to the controller.254. Connect the controller to your Infiniband (IB) or Fibre Channel (FC) switch and host computer(s).255. Connect your RS-232 terminal to the controller.256. Power up the system.257. Configure the storage array (create and format LUNs - Logical Units) via RS-232 interface, Telnet, or GUI.258. Define and provide access rights for the clients in your SAN environment. Shared LUNs need to be managed by SAN management software. Individual dedicated LUNs appear to the client as local storage and do not require management software.259. Initialize the system LUNs for use with your server/client systems. Partition disk space and create file systems as needed.252.1 Setting Up the Controller252.2 Unpacking the System262.2.1 Rack-Mounting the Controller Chassis262.2.2 Connecting the Controller in Dual Mode261. Connect the LINK ports on the two controller units using the supplied cable.262. Connect the COM ports on the two units using the supplied cable.262.2.3 Connecting the Controller271. There are 10 disk channels on the controller. They correspond with disk ports. The disk ports are labeled as follows (Figure ...27Figure 2-1 I/O Connectors272. Each controller supports up to four host connections. You may connect more than four client systems to the controller using switches and you can restrict user access to the LUNs (as described in Section 2.3 "Configuring the Controller" of this guide).272.2.4 Selecting SAS- ID for Your Drives272.2.5 Laying Out your Storage Drives272.2.6 Connecting the RS-232 Terminal281. Connect your terminal to the CLI port at the back of the controller using a standard DB-9 female- to-male null modem cable (Figure 2-2).28Figure 2-2 Controller CLI Port282. Open the terminal window.283. Use the following settings for your serial port:282.2.6.1 Basic Key Operations28Table 2-1 Basic Key Assignments292.2.7 Powering On the Controller291. Verify that the power switches on the two (2) power supply module at the back of each controller are off.292. Connect the two AC connectors, using the power cords provided at the back to the AC power source for each controller unit. For maximum redundancy, connect the two power connectors to two different AC power circuits for each unit.293. Check that all your drive enclosures are powered up.294. Check that the drives are spun up and ready.295. Turn on the power supplies on the controller unit(s). The controller will undergo a series of system diagnostics and the bootup sequence is displayed on your terminal.296. Wait until the bootup sequence is complete and the controller system prompt is displayed.292.3 Configuring the Controller302.3.1 Planning Your Setup and Configuration30Figure 2-3 Striping Across Tiers - RAID302.3.2 Configuration Interface312.3.3 Login as Administrator311.

Use the NETWORK command to display the current settings (Figure 4-2).992. Change the controller’s IP address for your network environment: network IP=<new IP address>.993. Change the netmask of the controller (if needed): network netmask=<new netmask>.994. Enable the Telnet capability (if needed): network telnet=ON.995. Decide whether the SNMP functionality should be enabled.100Figure 4-2 Current Network Configuration Screen1006. If the SNMP function is enabled, enter the IP address of the computer to be used to monitor the SNMP traps: network trapip=<computer’s IP address>1007. Decide whether the Syslog capability should be enabled. To enable (ON) or disable (OFF) the Syslog, enter: network syslog=on|off1008. If the SYSLOG function is enabled, enter the destination IP address for the Syslog packets: network SYSLOGIP=<destination IP address>1009. The default destination port number for Syslog packets is 514. To change it, enter: network SYSLOGPORT=<port number>10010. Set up the routing table. This table describes how the controller communicates with the hosts on other networks. Use the ROUTE command to display the current settings (Figure 4-3).100Figure 4-3 Current Controller Routing Table10111. On boot up, verify the network connections, enter NETWORK PING=<IP address of a network system>.101a) Ping a host on the same subnet as the controller.101b) Ping another host on a different subnet.10112. Make sure your firewall is running (which will block traffic and keep hosts from talking to each other), ensure it is set up to allow the controller to pass information on Port 23 (for Telnet), Port 161 (for SNMP), and Port 162 (for SNMP traps).1014.1.3 Login Names and Passwords1014.1.4 SNMP Set Up on Host Computer1021. Ensure the host computer, which will receive the traps, has an SNMP browser (such as HP OpenView) properly installed and configured. Refer to your browser’s documentation for instructions on how to load the MIB files.1022. Set up the host computer to listen to Ports 161 and 162.1023. Load the following controller MIB. Note these MIB files:1024. Start a query. You should be able to see various controller information such as tempLevel, powerNumber, fanNumber, powerTable, tierNumber, and tierTable.1025. To verify that the SNMP function has been set up correctly:102a) Unplug one of the power supplies.102b) Check that a power failure message appears in your SNMP browser.1024.1.4.1 Controller Implementation of SNMP102InfiniteStorage 15000 MIB (The InfiniteStorage 15000 MIB is read only.)1024.1.4.2 Traps1034.2 Troubleshooting the Controller1034.2.1 Component Failure Recovery1034.2.1.1 Power Supply Failure103Figure 4-4 Power Modules - Front View1031.
