1 General description The HP StorageWorks 8/20q Fibre Channel Switch (Figure 1) is a 20-port, 8-Gb/s switch with both Ethernet and serial management interfaces.
Switch LEDs and controls The switch LEDs provide information about the switch’s operational status. These LEDS include the Input Power LED (green), Heartbeat LED (green), and the System Fault LED (amber) (Figure 2). For information about port LEDs, see ”Port LEDs” on page 14. The Maintenance button (Figure 2) is the only switch control. It is used to reset a switch or to recover a disabled switch.
Maintenance button The Maintenance button (Figure 2) is a dual-function momentary switch on the front panel. Its purpose is to reset the switch or to place the switch in maintenance mode. Maintenance mode sets the IP address to 10.0.0.1 and provides access to the switch for maintenance purposes when flash memory or the resident configuration file is corrupted. For more information, see ”Recovering a switch using maintenance mode” on page 46.
Fibre Channel ports The 8/20q Fibre Channel Switch has twenty Fibre Channel ports. Ports are numbered 0–19 (Figure 3). Each of the ports is served by a Small Form-Factor Pluggable (SFP+) transceiver and is capable of 8-Gb/s, 4-Gb/s, or 2-Gb/s transmission. SFPs are hot-pluggable. User ports can self-discover both the port type and transmission speed when connected to devices or other switches.
Transceivers The 8/20q Fibre Channel Switch supports SFP+ optical transceivers for the Fibre Channel ports. A transceiver converts electrical signals to and from optical laser signals to transmit and receive data. Duplex fiber optic cables plug into the transceivers which then connect to the devices. A port is capable of transmitting at 8 Gb/s, 4 Gb/s, or 2 Gb/s; however, the transceiver must also be capable of delivering at this rate. The SFP+ transceivers are hot-pluggable.
Serial port The 8/20q Fibre Channel Switch is equipped with an RS-232 serial port for maintenance purposes (Figure 6). You can manage the switch through the serial port using the CLI. 2 1 1 Serial port 2 RS-232 connnector pin identification Figure 6 Serial port and pin identification The serial port connector requires a null-modem F/F DB9 cable. The pins on the switch RS-232 connector (Figure 6) are identified in Table 2.
Switch management The switch supports the following management tools and protocols: • QuickTools web applet, page 17 • Simple SAN Connection Manager, page 17 • Command line interface, page 17 • Simple Network Management Protocol, page 17 • Storage Management Initiative–Specification (SMI-S), page 17 • File transfer protocols, page 17 QuickTools web applet QuickTools is a browser-based graphical user interface (GUI) that provides switch management capabilties beyond those of Simple SAN Connection Manager.
2 Planning Consider the following when planning a fabric: • Devices, page 19 • Device access, page 19 • Performance, page 20 • Feature licenses, page 21 • Multiple switch fabrics, page 21 • Switch services, page 22 • Fabric security, page 23 • Fabric management, page 26 Devices When planning a fabric, consider the number of devices and the anticipated demand. This will determine the number of ports that are needed and in turn the number of switches. Consider the transmission speeds of your HBAs and SFPs.
A zoning database is maintained on each switch. Table 3 describes the zoning database limits, excluding the active zone set. Table 3 Zoning database limits Limit Description MaxZoneSets Maximum number of zone sets (256). MaxZones Maximum number of zones (2,000). MaxAliases Maximum number of aliases (2,500). MaxTotalMembers Maximum number of zone and alias members (10,000) that can be stored in the zoning database. Each instance of a zone member or alias member counts toward this maximum.
Latency Latency is a measure of how fast a frame travels through a switch from one port to another. The factors that affect latency include transmission rate and the source/destination port relationship (Table 4). Table 4 Port-to-port latency Destination Rate Source Rate Gbps 2 4 8 2 < 0.6 μsec < 0.7 μsec1 < 0.6 μsec1 4 < 0.4 μsec < 0.3 μsec < 0.4 μsec1 8 < 0.3 μsec < 0.2 μsec < 0.2 μsec 1. Based on minimum frame size of 36 bytes. Latency increases for larger frame sizes.
Domain ID, principal priority, and domain ID lock The following switch configuration settings affect multiple switch fabrics: • Domain ID • Principal priority • Domain ID lock The domain ID is a unique number from 1–239 that identifies each switch in a fabric. The principal priority is a number (1–255) that determines the principal switch which manages domain ID assignments for the fabric. The switch with the highest principal priority (1 is high, 255 is low) becomes the principal switch.
• Secure Socket Layer (SSL): Provides for secure SSL connections for the QuickTools web applet and SMI-S. This service must be enabled to authenticate users through a Remote Authenticaton Dial-in Service (RADIUS) server. To enable secure SSL connections, you must first synchronize the date and time on the switch and the workstation. Enabling SSL automatically creates a security certificate on the switch. The default is disabled. NOTE: Simple SAN Connection Manager version 1.
Fabric security consists of the following: • Connection security, page 24 • User account security, page 24 • Port binding, page 25 • Device security, page 25 Connection security Connection security provides an encrypted data path for switch management methods. The switch supports the Secure Shell (SSH) protocol for the command line interface and the Secure Socket Layer (SSL) protocol for management applications such as QuickTools and SMI-S. Use the CLI to configure SSH and SSL.
Port binding Port binding provides authorization for a list of up to 32 switch and device WWNs that are permitted to log in to a particular switch port. Switches or devices that are not among the 32 are refused access to the port. Consider what ports to secure and the set of switches and devices that are permitted to log in to those ports. Use the CLI to configure port binding.
Fabric management The Simple SAN Connection Manager application is a GUI-based management application for HP StorageWorks that runs on the management station. It provides basic automated configuration and management of switches, HBAs, and storage devices. Switch management functions include IP address configuration and limited control of zoning. The browser-based application, QuickTools, and the CLI reside in the switch firmware and provide for the management of individual switches in a single fabric.
3 Installation This section describes how to install and configure the switch.

Rack the switch 1. Remove and discard the four 10-32 screws from the sides of the switch. 2. Attach each rail to the switch using two 10-32 x .375-inch screws with captive washers (Figure 7). Make sure the slotted ends of the rails are on the power-supply side (not the SFP-port side) of the switch. Figure 7 Attaching the rails to the switch 3. On the rack vertical posts, mark the holes that will be used by the rail flanges (three on each rear vertical post, two on each front vertical post).
5. Fasten each rail flange to the front of the rack using two M6 machine screws (Figure 10). Figure 10 Fastening the rail to the front of the rack 6. Fasten each slotted-rail end to the rear mounting bracket using a flat washer and a 1/4-20 hex nut (Figure 11). Figure 11 Fastening the rail to the rear mounting bracket 7. Optional: Fasten the filler panel to the rear mounting brackets with two M6 machine screws (Figure 12).
Install the transceivers A small form-factor pluggable (SFP) transceiver is required for each switch port that will be connected to a device or another switch. SFPs are not included with the switch. Only HP SFPs are supported for use in the switch. To install an SFP transceiver, insert the transceiver into any of the active switch ports and gently press until it snaps in place. TIP: The transceiver will fit only one way. If the transceiver is not installed under gentle pressure, flip it over and try again.

CLI switch configuration To configure the switch using the command line interface. 1.
You can load and activate firmware upgrades on an operating switch without disrupting data traffic or re-initializing attached devices. If you attempt to perform a non-disruptive activation without satisfying the following conditions, the activation will fail. If the non-disruptive activation fails, you will usually be prompted to try again later. Otherwise, the switch will perform a disruptive activation.
One-step firmware installation The firmware install and image install commands download the firmware image file from an FTP or TFTP server to the switch, unpack the image file, and perform a disruptive activation in one step.
Custom firmware installation A custom firmware installation downloads the firmware image file from an FTP or TFTP server to the switch, unpacks the image file, and resets the switch in separate steps. This allows you to choose the type of switch reset and whether the activation will be disruptive (reset switch command) or nondisruptive (hotreset command). The following example illustrates a custom firmware installation with a nondisruptive activation. 1.

In the Add License Key dialog, enter the license key in the Key field. 4. Click Get Description to display the upgrade description. 5. Click Add to upgrade the switch.
4 Diagnostics and troubleshooting Diagnostic information about the switch is available through the switch LEDs and the port LEDs. Diagnostic information is also available through the CLI, QuickTools, or Simple SAN Connection Manager event logs and error displays. This section describes the following types of diagnostics: • Switch diagnostics, page 41 describes the Input Power LED and System Fault LED indications.
System fault LED is illuminated The System Fault LED illuminates to indicate that a fault exists in the switch firmware or hardware. If the System Fault LED illuminates, identify the Heartbeat LED error blink pattern and take the necessary actions. See ”Heartbeat LED blink patterns” on page 42. Power-On self test diagnostics The switch performs a series of tests as part of its power-up procedure.
Fatal POST error blink pattern A system error blink pattern is 3 blinks followed by a 2-second pause. The 3-blink error pattern indicates that a POST failure or a system error has left the switch inoperable. If a system error occurs, contact your authorized maintenance provider. Momentarily press and release the Maintenance button to reset the switch. 2 seconds Configuration file system error blink pattern A configuration file system error blink pattern is 4 blinks followed by a 2-second pause.
Logged-in LED indications Port diagnostics are indicated by the Logged-in LED for each port (Figure 15). 1 2 1 Logged-in LED (port 0) 2 Logged-in LED (port 10) Figure 15 Logged-in LED The Logged-in LED has three indications: • Continuous illumination: A device is logged in to the port. • Flashing once per second: A device is logging in to the port, or the port is in the diagnostics state. • Flashing twice per second: The port is down, offline, or an error has occurred.
3. Display the fabric domain IDs using the show domains CLI command or by selecting the QuickTools Switch tab, Summary icon. Are all domain IDs in the fabric unique? • Yes—Continue. • No—Correct the domain IDs on the offending switches using the set config switch CLI command or the QuickTools Switch Properties dialog. Reset the port. If the condition remains, continue. 4.
Review the event browser to determine if excessive port errors are responsible for disabling the port. Look for a message that mentions one of the monitored error types indicating that the port has been disabled, then perform the following procedure: 1. Examine the alarm configuration for the associated error using the show config threshold CLI command. See the show config threshold CLI command in the HP StorageWorks 8/20q Fibre Channel Switch command line interface guide.
4. The maintenance menu displays several recovery options. To select a switch recovery option, press the corresponding number (displayed in option: field) on the keyboard and press Enter. 0) Exit 1) Image Unpack 2) Reset Network Config 3) Reset User Accounts to Default 4) Copy Log Files 5) Remove Switch Config 6) Remake Filesystem 7) Reset Switch 8) Update Boot Loader Option: These options and their use are described in the following subsections.
Copying log files in maintenance mode (option 4) The Copy Log Files option copies all log file buffers to a file on the switch named logfile. You can use FTP to download this file to the workstation, however, you must download logfile before resetting the switch. For information about downloading files from the switch, see the HP StorageWorks 8/20q Fibre Channel Switch command line interface guide.
