1 Introduction The HP 6Gb SAS BL Switch is a single-wide interconnect module for HP BladeSystem c-Class enclosures that enables a server blade with an HP Smart Array 6Gb SAS Controller to communicate with external SAS storage enclosures and tape devices. Its 6Gb SAS technology delivers high performance, with high data bandwidth up to 600 MB/s per physical link, and is fully compatible with 3G SAS, 3G SATA, and 1.5G SATA technology.
Supported devices The HP 6Gb SAS BL Switch supports the following types of devices: • “Shared SAS storage enclosures (P2000 G3 SAS MSA arrays)” (page 6) • “Zoned SAS storage enclosures (MDS600, D6000, and D2600/D2700 drive enclosures)” (page 6) • “Tape devices” (page 7) For information about cabling and configuring the switch and any attached devices, see “Connecting cables to the switch” (page 15).
• The SAS BL Switch and the connected SAS storage are configured using drive bay zone groups. The group of drive bays is presented to the c-Class enclosure blade port (server bay) as if it was directly connected to that server bay. NOTE: Unpopulated drive bays in the storage enclosure can be included in a zone group, to help plan for future growth. • • The server bay that needs access to drive bays must be assigned to the appropriate zone group. ◦ A server bay can be assigned multiple zone groups.
2 Component identification 1 Unit ID LED Blue • Off—Normal • Solid —Being identified • Blinking—Firmware is being updated 2 Health LED Green • Off—Not powered up • Solid green—Healthy Amber • Off—Not powered up • Blinking—Error, there is a problem with the switch 3 Locking latch handle 4 Link LED Green • Off—No link between the server and storage • Solid —Link between server and storage is established • Steady blink (1Hz)—Switch hardware or software is starting up.
3 Installation procedures HP 6Gb SAS BL Switch installation procedures include the following steps: • “Getting started” (page 9) • “Planning the configuration” (page 9) • “Selecting the interconnect bay” (page 10) • “Installing the switch” (page 11) • “Accessing the switch” (page 13) • “Updating switch firmware” (page 13) • “Connecting cables to the switch” (page 15) • “Configuring the switch” (page 17) Getting started • Familiarize yourself with information available on the HP BladeSystem
For assistance, HP strongly recommends using the HP BladeSystem Deployment Guide for Solutions with 6Gb SAS BL Switches and External SAS Storage Enclosures. The deployment guide provides guidelines, instructions, and configuration examples for solutions centered around an HP BladeSystem c-Class enclosure with server blades, SAS BL switches, SAS controller cards, and external SAS storage enclosures.

1. Remove the air baffle from the selected interconnect bay. 2. Prepare the switch. 3. Install the switch in the open interconnect bay. When installed in an operational enclosure, the switch automatically powers up and performs a series of Power On Self Tests before being operational. NOTE: Do not connect cables to the switch at this time. HP recommends connecting cables only after confirming that the switch is operational and has the desired, supported version of firmware installed.
4. Note the following during startup: • All eight switch Link LEDs will blink while the switch and the VSM software are starting up. • Startup time is approximately five minutes. If startup is longer than five minutes, confirm that a supported version of Onboard Administrator is installed on the system. • After the switch and the VSM software have started up successfully, the switch Health LED will be solid green.
IMPORTANT: • Before updating switch firmware, HP strongly recommends backing up the existing configuration for safekeeping. For more information, see the HP 6G Virtual SAS Manager User Guide, available on the 6Gb SAS BL Switch page of the HP Support Center website (http:// www.hp.com/go/hpsc). • When two HP 6Gb SAS BL Switches are installed in the same row of an enclosure, make sure that they are running the same firmware version.
Connecting cables to the switch After confirming that the desired firmware is installed on the switch, connect SAS cables between the switch and the external SAS storage enclosures or external backup devices. Per your configuration plan, connect the external devices to switch ports that the desired servers will be able to access. (See “Getting started” (page 9) and “Planning the configuration” (page 9).) The 6Gb SAS BL Switch uses SAS cables with mini-SAS universal connectors.
Cabling example The following is one example of a configuration using HP 6Gb SAS BL Switches. For more information about configurations using HP 6Gb SAS BL Switches, see the HP BladeSystem Deployment Guide for Solutions with 6Gb SAS BL Switches and External SAS Storage Enclosures, available on the BladeSystem Interconnects page of the HP Support Center website (http:// www.hp.com/go/hpsc).
Configuring the switch Key configuration tasks include: 1. Entering switch parameters. (Enabling or disabling Multi-initiator mode.) 2. Creating zone groups. 3. 4. • Switch-port zone groups: For shared SAS storage enclosures (P2000 G3 SAS MSA) and tape libraries. • Drive-bay zone groups: For zoned SAS storage enclosures (D6000, MDS600, and D2600/D2700). Assigning zone groups to servers (c-Class enclosure device bays). Capturing the configuration for safekeeping.
4 Supported software tools Primary configuration and management utilities include: • “HP Onboard Administrator overview” (page 18) • “HP 6G Virtual SAS Manager overview” (page 20) HP Onboard Administrator overview HP BladeSystem Onboard Administrator (OA) is the enclosure management processor, subsystem, and firmware base used to support the HP BladeSystem c-Class enclosures and the managed devices contained within the enclosure.
As shown in the following image, selecting an item in the navigation tree displays management and monitoring tasks for the selected device. For example, when a SAS BL Switch installed in interconnect bay 5 is selected in the navigation tree, additional information about the device is displayed, with tabs at the top of the display providing additional functions.
HP 6G Virtual SAS Manager overview HP 6G Virtual SAS Manager (VSM) is embedded in the HP 6Gb SAS BL Switch firmware and is the software application used to create hardware-based zone groups to control access to external SAS storage enclosures and tape devices. Servers in the c-Class enclosure are then granted access to these zone groups, allowing them to access the storage.
5 Firmware As part of a routine system maintenance program, periodically check firmware versions installed on all devices in your solution, including the SAS BL Switch. Updated firmware may include additional features and functions, performance enhancements, support for newly released hardware, or fixes to known issues. HP SAS BL Switch firmware updates can be performed using the HP Smart Update Firmware DVD or the HP Virtual SAS Manager (VSM) utility.
6 Troubleshooting Problem Solution Amber LED on Switch • Check OA and VSM for status alerts to identify the problem. • See “Component identification” (page 8) for LED definitions. Storage not ready during POST (blade) OR Controller lockup during POST Verify the power up sequence and allow sufficient time for each component to power up. Verify cabling from the switch to the storage enclosures. For more information about cabling, see “Connecting cables to the switch” (page 15).
