Power and Cooling Module (PCM)

Each iSR6250 chassis blade has a power and cooling module (PCM), located on the back-side of the chassis. Each PCM consists of one power supply, three fans, and one external status LED.

Introduction

Power and Cooling Module (PCM)

Figure 1-3 Power and Cooling Module (PCM)

Figure 1-4 PCM — Back Plate

Each blade is capable of simultaneously driving all six fans in both PCMs. Normally, only one blade controls both fans, running them at a normal speed. However, if the system detects higher than expected temperature on either side of the blade, it forces the fans to run at full speed. Once the temperature is back to normal, the fans resume running at their normal speed.

The following paragraphs describe the fan speed and temperature parameters listed in Table 1-1.

 High Fan Speed Temperature – When a sensor detects a temperature that

exceeds this value, the fan speed will run at their maximum RPM. The system logs the event and the system fault LED blinks five times every two seconds.

 Low Fan Speed Recovery Temperature – When the fans are running at

their maximum RPM and all sensors report values less than this value, the fan speed resets to normal.

 Critical Temperature – When a sensor detects a temperature that exceeds

this value, the system powers down the blade. When this happens, the CPUs enter sleep state 5; the system sets the PCI power state of capable devices to D3 and turns off the power supplies not essential to wake up the CPUs. When the temperature goes below the Recovery Temperature value, the sensor that reported the over temperature value will generate an SMB_ALERT.

 Recovery Temperature – Value at which a sensor will generate an

SMB_ALERT to wake up the CPU and cause the blade to reboot.

Router Blade LEDs

Each chassis blade provides LEDs and connectors that face the front of the chassis and may provide additional ports, depending on its model. The router blade LEDs shown in Figure 1-6 provide information about the router’s operational status. These LEDs include the heartbeat LED, the system fault LED, and the input power LED. The blade also includes a recessed beacon indicator used to locate the physical blade monitored using the SANsurfer Router Manager.

Heartbeat LED (Green)

The heartbeat LED blinks once a second as long the router firmware is operational.

System Fault LED (Amber)

The system fault LED lights up to show that a fault exists in the router firmware or hardware. Fault conditions include POST errors and over-temperature conditions. The LED shows a blink code for POST errors and the over temperature condition. See Figure 1-6 and Tab le 1 -2 .

Reset a Router Blade

To reset the router blade, use a pointed, nonmetallic tool to momentarily press and release (less than two seconds) the maintenance button. The router responds as follows:

1. All the router blade LEDs illuminate.

2. After about 2 seconds, the POST begins, turning off the heartbeat and system fault LEDs.

3. When the POST is complete, the power LED is on and the heartbeat LED flashes once per second.

Reset and Select Boot Image

You can reset the router using either the primary or secondary boot image:

 Primary Image – To reset the router and select the primary boot image, use

a pointed, nonmetallic tool to press and hold the maintenance button until the heartbeat LED flashes once, then release the button. The router will boot from the primary boot image. The boot time is less than one minute.

 Secondary Image – To reset the router and select the secondary boot

Reset IP Address

To reset the router and restore the maintenance port IP address to the default (10.0.0.1), use a pointed, nonmetallic tool to press and hold the maintenance button until the heartbeat LED flashes six times, then release the button. The router boots and sets the maintenance port to IP address 10.0.0.1. The boot time is less than one minute.

The IP address set by this method is not persistent; to make the change persistent, use the command line interface (CLI) or SANsurfer Router Manager to set the IP address. For more information, see the iSR6200 Router Manager User's Guide and the iSR6200 Router CLI User's Guide.

Fibre Channel Transceivers

Each port is served by a small form-factor pluggable (SFP) optical transceiver and is capable of 1-, 2-, 4-, or 8-Gbps transmission. SFPs are hot-pluggable. User ports can self-discover both the port type and transmission speed when connected to public devices or switches.

The iSR6250 router 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. For example, a 1-Gbps/2-Gbps Fibre Channel port can transmit at 1-Gbps or 2-Gbps; however, the transceiver must also be capable of delivering these rates.

The SFP transceivers are hot pluggable. You can remove or install a transceiver while the router is operating without harming the router or the transceiver. However, this interrupts communication with the connected device. See page 3-7 for information about installing and removing SFP optical transceivers.

2 Planning

This section describes how to plan for the iSR6250 router. The following sections describe the devices and services you need to consider when planning to use the iSR6250 router:

 “Devices” on page 2-1

 “Device Access” on page 2-2

 “FC Switches Required for VPGroups” on page 2-2

 “FC Performance” on page 2-2

 “iSCSI Performance” on page 2-3

 “Performance Tuning” on page 2-4

 “High Availability” on page 2-7

 “Management” on page 2-7

 “Recovery” on page 2-7

 “Services” on page 2-8

 “Security” on page 2-8

Devices

When planning to use the router, consider the number of devices and the anticipated demand. This determines the number of ports required and in turn the number of routers.

The router uses SFP transceivers in the 8-Gbps Fibre Channel (FC) ports, but some FC devices may not use the same transceivers. Consider whether the FC device you want to connect the router to uses SFP or gigabit interface converters (GBIC) transceivers, and choose fibre optic cables accordingly. Use LC-type cable connectors for SFP transceivers and SC-type cable connectors for GBIC transceivers. Also consider the transmission speed compatibility of your devices, host bus adapters (HBAs), switches, and SFPs.

SN0051103-00 A 2-1

Planning Device Access

Device Access

Consider device access needs within the FC and iSCSI SANs. Controlling access to FC device LUNs requires mapping FC device LUNs to specific iSCSI initiators. You may map LUNs to more than one initiator. Giving multiple initiators access to a LUN requires access management.

Fibre Channel

The Fibre Channel ports automatically discover all FC target devices, whether connected directly (loop) or by fabric (switch).

iSCSI

The iSCSI ports automatically present targets discovered on the Fibre Channel ports. If the FC target’s LUN 0 is a controller LUN, it becomes accessible (mapped) to all iSCSI initiators. All data LUNs are inaccessible until mapped. The exception to this is if LUN 0 is a controller LUN, then it is mapped automatically to allow for management of the FC target controller.

When an iSCSI initiator logs on, the router records the initiator’s iSCSI name and IP address. The management interface [command line interface (CLI) and SANsurfer Router Manager] uses the initiator information to simplify the mapping process.

FC Switches Required for VPGroups

iSR6250 uses QLogic HBA technology and is compatible with all Fibre Channel switches from Brocade, Cisco, McData, and QLogic. If you want to use more than one VPGroup, you must use Fibre Channel Switches.

FC Performance

The iSR6250 router supports Fibre Channel service at transmission rates of 2, 4, or 8 Gbps with a maximum frame size of 2148 bytes. Related performance characteristics include the following:

 Distance (see page 2-3)

 Bandwidth (see page 2-3)

 Latency (see page 2-3)

2-2 SN0051103-00 A

Distance

Consider the physical distance between Fibre Channel devices. Choose SFP transceivers that are compatible with the cable type and distance.

Each Fibre Channel port is supported by a data buffer with a three-credit capacity; that is, three maximum sized frames. For fibre optic cables, this enables full bandwidth over the following approximate distances:

 5 kilometers at 1 Gbps (0.6 credits/Km)

 2.5 kilometers at 2 Gbps (1.2 credits/Km)

Beyond these distances, however, the connection loses some efficiency because the transmitting port must wait for an acknowledgement before sending the next frame.

Bandwidth

Bandwidth is a measure of the volume of data that can be transmitted at a given transmission rate. A 1-Gbps/2-Gbps FC port can transmit or receive at nominal rates of 1- or 2-Gbps, depending on the device to which it is connected. This corresponds to actual bandwidth values of 106 MB and 212 MB, respectively.

Planning

iSCSI Performance

Latency

Latency is a measure of how fast a transaction travels through the router.

iSCSI Performance

The iSR6250 router supports Ethernet service at transmission rates of 1000-, 100or 10-Mbps with an MTU size of 1500 or 9000 (jumbo frames).

NOTE:

An MTU size greater than 1500 should only be used when the router is connected to a 1000 Mbps Ethernet network.

Related performance characteristics include the following:

 Distance

 Bandwidth

 Latency

Distance

Consider the physical distance between routers.This is usually measured in round-trip delay. Round-trip delays range anywhere from less than 1 millisecond to as great as 250 milliseconds.

SN0051103-00 A 2-3

Planning Performance Tuning

Bandwidth

Bandwidth is a measure of the volume of data that can be transmitted at a given transmission rate. WAN data rates range from 1.5 megabits per second (T1) to greater than 600 megabits per second (OC-12).

Latency

Latency is a measure of how fast a transaction travels through the router and LAN/WAN.

Performance Tuning

Proper configuration maximizes the router’s performance. Knowing the round trip delay (distance between the router and iSCSI initiators) and WAN effective data rate (connection type) allows you to tune the router for optimal performance. The following tables provide TCP Window Size settings for specific WAN environments. The TCP Window Size is configured as two parameters: Window

Size and Scaling Factor. See the iSR6200 Router Manager User's Guide and the iSR6200 Router CLI User's Guide for configuring the TCP window size.

High Availability

A dual-blade iSR6250 router supports high availability, which provides link-level, switch-level, and blade-level failure protection. To make this effective, you must connect the iSCSI hosts to both iSR6250 blades. For details, see “Connecting

iSCSI Hosts to your iSR6250” on page 4-13.

Management

The SANsurfer Router Manager application and CLI run on a management workstation used to configure, control, and maintain the router. Support platforms include Windows, Solaris, and Linux. The SANsurfer Router Manager application is installed and executed on the workstation.

The router supports the following management interfaces:

 SANsurfer Router Manager – Graphical user interface (GUI) application,

which runs on a management workstation (see the iSR6200 Router Manager User's Guide).

Planning

NOTE:

Services

You can configure your router to suit the demands of your environment using a variety of router services. Familiarize yourself with the following router services and determine which ones you need:

 Telnet – Enables you to manage the router over a telnet connection.

 Router management – Provides for out-of-band management of the router

 Simple network management protocol (SNMP) – Enables you to monitor

the workstation dates and times with an NTP server. NTP is disabled (not configured) by default.

Security

 File transfer protocol (FTP) – Enables you to transfer files rapidly between

the workstation and router using FTP.

 Secure SHell (SSH) – Provides secure and encrypted connections to

traditionally non-encrypted services.

Passwords provide router security. The SANsurfer Router Manager requires a password each time a user logs into the application. Once connected, the SANsurfer Router Manager prompts for an administrative password before it accepts configuration changes.

The CLI also requires the user to enter a user ID and password to start. CLI must be in an admin session to perform any set operations. An admin session requires a password.

The default password for both these management tools is password for the default user ID of guest. The default administrative password is config.

Once logged on, you can change the password using the application’s security features.

4 Configuration

This section describes how to configure the iSR6250 router to support virtual port groups (VPGs) and LUN mapping.

Some storage arrays limit the number of LUNs exposed to a host to 256 LUNs. Each iSR6250 router blade supports up to four virtual port groups (VPGs), making it possible for these storage arrays to present up to 1024 LUNs per blade.

When configuring VPGs on the iSR6250 router, follow these guidelines:

 All Fibre Channel (FC) virtual ports from a single VPG must be part of only

one logical host on the storage array.

 FC ports from different VPGs must not be part of the same logical host on

the storage array.

 A given LUN can be presented to one and only one VPG. It can be

presented to other FC hosts, but only one VPG on a given iSR6250 router (chassis).

The following sections describe how to configure VPGs and the Fibre Channel arrays connected to them:

 “Enabling Virtual Port Groups” on page 4-2

 “Zoning Virtual Port Groups on the SAN” on page 4-9

 “Configuring FC Array Hosts and LUN Assignments with the iSR6250” on

page 4-10

 “Controlling per Host LUN Access on the iSR6250” on page 4-20

SN0051103-00 A 4-1

Configuration Enabling Virtual Port Groups

Enabling Virtual Port Groups

Each iSR6250 router blade has one virtual port group (VPG) enabled by default, which gives the iSCSI hosts access to 256 LUNs. You can enable and configure additional VPGs to give the iSCSI hosts access to more than 256 distinct LUNS from a given FC Target Array.

Each blade has VPG 1 enabled by default; VPG 1 is the primary virtual port group and cannot be disabled. Enabling additional virtual port groups creates additional logical FC HBA initiator ports on the fabric. These ports act as separate FC HBA host ports, and additional 256 LUNs can be presented to each of them. With all four VPGs enabled, a single iSR6250 blade can access up to1024 LUNs from a single target WWPN.

You can display virtual port group information using the show vpgroups command in the CLI, as shown in the following example.

Zoning Virtual Port Groups on the SAN

When connecting the iSR6250 for high availability, connect one FC port from each blade to each of your fabrics (see Figure 4-5). This topology provides link-level, switch-level, and blade-level failure protection. To make this effective, you must connect the iSCSI hosts to both iSR6250 blades. For details, see “Connecting

iSCSI Hosts to your iSR6250” on page 4-13.

Any of these LUNs can be presented to any number of other FC hosts on the array; but can be presented to one and only one VPG of the iSR6250.

Configuring FC Array Hosts and LUN Assignments with the iSR6250

Figure 4-8 shows presenting LUN 3 incorrectly. If an iSCSI host logged into both

VPG0 and VPG1 it will have access to LUN 3 through 2 Virtual port groups. This is invalid and will lead to serious problems.

Figure 4-8 Incorrectly Presenting LUN 3

Presenting the LUN at different LUN indexes for each VP will confuse the iSCSI host MPIO software because it will see the same LUN WWLUNID at two different indexes. This would cause the MPIO driver to panic or crash. Without an MPIO driver, you want to avoid.

Connecting iSCSI Hosts to your iSR6250

Upon logging into a Fibre Channel target WWPN, an iSR6250 blade will present an iSCSI Target for iSCSI initiators to connect to. This target is defined by its iSCSI Qualified Name (IQN) string. To connect iSCSI initiators to Fibre Channel targets through the iSR6250 correctly, it is important to understand the composition of the iSCSI target IQN string.

The following example shows the anatomy of a sample IQN string from an iSR6250 router:

iqn.2004-08.com.qlogic:isr6250.0834e00019.b1.01.20030020c2075970

Configuration

1. Vendor name and registration date

2. Product Name

3. iSR6250 Chassis Serial Number

4. Blade (b1 or b2)

5. VPGroup (01 through 04)

6. FC target WWPN

Notice that the IQN string does not contain any information about which iSR6250 physical iSCSI port you are connecting to. iSCSI load balancing and failover are handled by the iSCSI host and not on the iSR6250.

Also notice the IQN string does not contain any information about which physical Fibre Channel port on the iSR6250 the FC target device is attached through.

iSCSI host LUN access will be determined by the specific iSCSI target the host connects to, and the LUNs that VPG has access to from the storage array. Pay special attention to the VPG index of the IQN string you are logging into; it determines which group of LUNs on the Storage Array your host can access.

Controlling per Host LUN Access on the iSR6250

The iSR6250 allows multiple iSCSI initiators to connect to a single FC target through a given VPG. Controlling individual LUN access for each iSCSI host requires LUN mapping devices connected through the iSR6250.

NOTE:

Before proceeding with this section, be sure you have read and understand the previous sections of this chapter.

Figure 4-13 shows that even after logging into the VPG0 iSCSI target, the host

cannot access data LUNs on the storage array. To allow the iSCSI host access to each LUN, you must configure the iSR6250 using either the SANsurfer Router Manager or the command line interface (CLI).

 System Fault LED is On (see page 5-2)

SN0051103-00 A 5-1

Diagnostics and Troubleshooting Power-On Self-Test Diagnostics

Input Power LED is Off

The input power LED lights up to show that the router logic circuitry is receiving proper voltages. If the input power LED is off, do the following:

 Inspect power cord and connectors. Is the cord unplugged? Is the cord or

connector damaged?

 Yes – Make necessary corrections or repairs. If the condition remains,

continue.

 No – Continue.

 Inspect AC power source. Is the power source delivering the proper voltage?

 Yes – Continue.

 No – Make the necessary repairs. If the condition remains, continue.

 Replace the router.

System Fault LED is On

The System fault LED will blink a specific pattern to indicate the problem. If the system

fault LED lights up, take necessary actions (see page 5-3).

Power-On Self-Test Diagnostics

The router performs a series of tests as part of its power-on procedure. The POST diagnostic program performs the following tests:

 Memory

 FLASH validation

 PCI device discovery

 Management Ethernet port

5-2 SN0051103-00 A

LED Blink Patterns

The heartbeat and system fault LEDs show the operational status of the router. When the POST completes with no errors, these LEDs blink at a steady rate of once per second. When the router is in maintenance mode, the heartbeat and system fault LEDs are on continuously.

Diagnostics and Troubleshooting

LED Blink Patterns

system fault blink patterns show critical errors. The heartbeat LED shows

Table 5-1. System Fault LED Blink Patterns

System Fault LED Condition

Heartbeat Blink Pattern

A blink pattern on the heartbeat LED of one second ON followed by one second OFF means that the router is operating normally. The heartbeat LED shows this pattern when the router firmware is operational

System Error Blink Pattern

The system fault LED generates a three-blink pattern (once per second) followed by a two second pause to indicate a system error.

SN0051103-00 A 5-3

Diagnostics and Troubleshooting LED Blink Patterns

Management Port IP Address Conflict Blink Pattern

The system fault LED generates a four-blink pattern (once per second) followed by a two second pause when the router detects an IP address conflict on the management Ethernet port.

You can clear the IP address conflict blinking using the CLI or SANsurfer Router Manager. Use the beacon OFF function.

Over-Temperature Blink Pattern

The system fault LED generates a five-blink pattern (once per second) followed by a two second pause when the router is in an over-temperature condition. That is, the air temperature inside the router is over the failure temperature of 70 (158

°F).

°C

If the system fault LED shows the over temperature blink pattern, do the following:

 Inspect the chassis air vents. Are the intake and exhaust vents clear?

 Yes – Continue

 No – Remove any debris from the fan intake and exhaust if necessary.

If the condition remains, continue.

 Consider the ambient air temperature near the router and clearance around

the router. Make necessary corrections. If the condition remains, open a command line window and log on to the router. Enter the shutdown command, then power down the router. Contact your authorized maintenance provider.

Recovering a Router

You may have to recover a router for one of the following reasons:

 The password was changed and has been forgotten.

 The router’s management IP address is unknown.

To recover the router’s password, reset the password to the default by using the maintenance button (see page 1-7).

You can recover the router’s IP address using either of the following methods:

 Connect to the serial console port (see page 1-12), then use the CLI set

mgmt command to reconfigure the management port (see the iSR6200 CLI

User’s Guide).

 Use the maintenance button to reset the management port’s IP to the factory

default of 10.0.0.1 (see page 1-7).

6 Removal/Replacement

This section describes how to remove and replace the following field replaceable units (FRUs):

 “SFP Transceivers” on page 6-1

 “iSR6250 Chassis Blades” on page 6-2

 “Power and Cooling Modules” on page 6-6

SFP Transceivers

You can remove and replace the SFP transceivers while the iSR6250 router is operating without damaging the router or the transceiver. However, this interrupts transmission on the affected port until you install the transceiver.

 To remove a transceiver, gently press the transceiver into the port to release

the tension, then pull the release tab or lever and remove the transceiver. Different transceiver manufacturers have different release mechanisms. Consult the documentation for your transceiver.

 To install a transceiver, insert it into the port and gently press until it snaps in

place.

NOTE:

The SFP transceiver fits only one way. If the SFP does not install under gentle pressure, flip it over and try again.

Removal/Replacement iSR6250 Chassis Blades

iSR6250 Chassis Blades

The iSR6250 router provides an enhanced facility you can use to replace any blade in the field. When you replace a blade, it automatically restores all the configuration data from the other blade.

The following sections show how to remove and replace a failed blade in the iSR6250 dual-blade chassis:

 “Removing the Failed Blade” on page 6-2

 “Installing a New Replacement Blade” on page 6-4

Removing the Failed Blade

To remove a failed blade from an iSR6250 chassis:

1. Log all iSCSI initiators out of the iSR6250 blade you are replacing prior to replacing the iSR6250 router blade.

2. Disconnect all cables from the iSR6250 blade you are replacing. This includes Fibre Channel, iSCSI, management, Ethernet, and serial cables.

Removal/Replacement Power and Cooling Modules

Power and Cooling Modules

Each iSR6250 chassis blade has a power and cooling module (PCM), located on the back side of the chassis. Each PCM consists of one power supply, three fans, and one external status LED.

The PCM’s external status LED shows its status:

 Green = GOOD status, indicating that the PCM is running as expected.

 Amber = FAULT status, indicating that the PCM has failed.

You can remove and replace a failed PCM as described in the following sections:

 “Removing the Failed PCM” on page 6-6

 “Installing a New PCM” on page 6-8

Removing the Failed PCM

To remove a failed PCM from the iSR6250 chassis:

1. Locate the failed PCM unit on the back side of the iSR6250 chassis. A failed PCM unit displays an amber color status LED.

Figure 6-5 shows the back side of two PCMs installed in a chassis

configured with two iSR6250 chassis blades. The PCM on the left side displays its fault indicator in amber, which indicates a FAULT status. The PCM on the right side displays its fault indicator in green, which indicates a GOOD status.
