High availability

The following features contribute to the SAN768B’s high-availability design:
v Redundant, hot-swappable blades and FRUs v Enhanced data integrity on all data paths v Fabric Shortest Path First (FSPF) rerouting around failed links v Integration with Simple Network Management Protocol (SNMP) managers v Automatic control processor failover v Nondisruptive ″hot″ software code loads and activation v Easy configuration, save, and restore v Hot-swappable World Wide Name (WWN) cards
The high-availability software architecture of the SAN768B provides a common framework for all applications that reside on the system, allowing global and local status to be maintained through any component failure. High-availability elements consist of the High Availability Manager, the heartbeat, the fault/health framework, the replicated database, initialization, and software upgrade.
The High Availability Manager controls access to the standby control processor, facilitates software upgrades, prevents extraneous switchover activity, closes and flushes streams as needed, provides flow control and message buffering, and supports a centralized active and standby state.

Reliability

Serviceability

The SAN768B uses the following error detection and correction mechanisms to ensure reliability of data:
v Data is protected by the Error Detection and Correction mechanism, which
checks for encoder errors and fault isolation , such as cyclic redundancy checking (CRC), parity checking, checksum, and illegal address checking
v Power-on self test (POST) v Dual control processors that enable hot, nondisruptive fast firmware upgrades v Each control processor contains one serial port and two Ethernet ports, for
management and for service. Offline control processor diagnostics and remote diagnostics simplify troubleshooting. The standby control processor monitors diagnostics to ensure it is operational, should a failover be necessary
v Bus monitoring and control of blades and other field-replaceable units (FRUs).
The SAN768B provides the following features to enhance and ensure serviceability:
v Modular design with hot-swappable components v Flash memory that stores two firmware images per control processor v Nonvolatile random-access memory (NVRAM), containing the OEM serial
number, IBM serial number, revision information, and part number information
v Background health-check daemon v Memory scrubber, self test, and bus ping to determine if a bus is not functioning v RASlog messages v SMI-S compliant v Watchdog timers

Software features

| | | | |
v Status LEDs v Predictive diagnostics analysis through Fabric Watch v SNMP (including version 3) integration with higher-layer managers
The Fabric OS allows any Fibre Channel-compliant device to attach to the switches as long as it conforms to the device login, name service, and related Fibre Channel standards. Each operating environment requires that a Fibre Channel host bus adapter (HBA) be available with a standards-compliant driver for correct interface to the fabric.
Fabric OS consists of a set of embedded applications running on top of an embedded Linux operating system kernel. These applications include:
v Name server v Alias server v Zone server v Simple Network Management Protocol (SNMP) agent v SMI-S compliant API v Syslog auditing v RCS (Reliable Commit Service) v NTP v Tasks to manage address assignment, routing, link initialization, fabric
initialization, link shutdown, shutdown, and the user interface.
v Integrated Routing–This feature allows any port in a SAN768B, SAN80B-4, and
SAN40B-4 to be configured as an EX_port supporting Fibre Channel (FC) routing. This eliminates the need to add a routing blade or use of the SAN18B-R for FC routing (FCR) purposes, and this also provides double the bandwidth for each FC router connection when connected to another 8 Gbps-capable port.

Security

Table 3 highlights some of the key security features available for the SAN768B and for other switches running Fabric OS 5.2.0 or newer.

Network Manageability

The SAN768B has a single domain and is managed as a single element with the Brocade Enterprise Fabric Connectivity Manager (EFCM) or Brocade Fabric Manager (FM). The SAN768B responds to its own IP address and appears as a separate entity to the Telnet protocol and SNMP.
NTPv3 (to synchronize timestamps)

Port numbering

All management interfaces, such as Telnet, Web Tools, standards compliant SMI-S, and Management Server, support a “port N within blade M” naming scheme.
The SAN768B supports SNMPv1 and SNPMv3. When SNMP devices send SNMP messages to a management console running SAN management software, the information is stored in a management information base (MIB). Fabric OS v6.0.0 and later supports the latest Fibre Alliance Fibre Channel Management (FCMGMT) and Storage Management Initiative (SMI) MIBs, which allow common information necessary for management software to provide information to a SAN administrator.
Note: Refer to the Fabric OS MIB Reference for additional MIB information.

svc00169
A fully populated SAN768B weighs approximately 104 kg (228 lb). Before you install it, verify that the additional weight of the chassis does not exceed the cabinet’s weight limit or unbalance the cabinet. When you calculate the additional weight, include the weights of all components that can potentially be added, to avoid overloading in the future.
Before you install a SAN768B into the cabinet, perform the following tasks:
v To ensure adequate cooling, plan to install the chassis with the port side facing
the aisle where exhaust air is released (usually called the service aisle). This prevents the fans from pulling in heated exhaust air.
v Plan for managing the cables before you install the chassis. A fully populated
SAN768B will have a large number of cables that must be carefully routed to minimize problems with installation and replacement of components, and in order

Chapter 3. Starting and configuring the SAN768B

Attention: Refer to the latest Fabric OS Release Notes or Interoperability Matrix
(see http://www.ibm.com/servers/storage/support/san) for information regarding Fabric OS compatibility. This is particularly important for fabrics with 1-Gbps switches using earlier Fabric OS versions.
The SAN768B must be configured before it is connected to the fabric, and all of the configuration commands must be entered through the active CP blade. The SAN768B configuration includes the following parameters:
v IP address and subnet mask for the SAN768B v IP addresses (or ″native″ IP address), host names, subnet masks, and gateway
addresses for both CP blades
v Switch name v Domain ID for the SAN768B (optional) v WWN for the SAN768B
Note: The SAN768B WWN is initially set by the factory to match the license ID
(which is based on the chassis serial number). The WWN can be changed, but the license ID cannot be modified.
configuration information is mirrored to the standby CP blade, which allows the
The most current configuration to remain available even if the active CP blade fails. The configuration information for the SAN768B is stored in the WWN blade and the flash memory of the CP blades. The configuration can be backed up to a workstation (uploaded) and then downloaded to the active CP blade if necessary.
The initial physical hardware installation continues with the following steps:
v “Providing power to the SAN768B” on page 26 v “Establishing a serial connection and logging on to the SAN768B” on page 26 v “Configuring the SAN768B IP addresses” on page 27
following additional steps are customer responsibilities required for the initial

the supplied power cords. Ensure the facility power receptacle is the
Use correct type, supplies the required voltage, and is properly grounded. (D004)
To provide power to the SAN768B:
1. Connect the AC power cords to the power supply assemblies. One to four power cords are required depending on electrical service.
2. Connect the power cords to a power source with voltage of 200 to 240 VAC, 47 to 63 Hz (normally two power cords).
3. Turn the AC power switches on the power supplies to ON (I). The AC power switches light green when switched on and power is supplied.
4. The SAN768B performs a power-on self-test (POST) each time it is powered on. POST takes approximately 10 minutes and is complete when indicator light activity indicates the operational state. For information about LED patterns, see Chapter 4, “Monitoring system components,” on page 33.
You can bypass POST by using the fastBoot command. You can also disable POST for successive reboots on the SAN768B using the diagDisablePost command.
Attention: To prevent a potential IP address conflict, do not connect the
SAN768B to the network until the IP addresses are configured.
To power off the SAN768B, see “Powering off the SAN768B” on page
Note:
109.

Establishing a serial connection and logging on to the SAN768B

Note: The preferred method of establishing a connection to the SAN768B is via the
serial port. However, if a serial connection is not possible (for example, if a serial cable is not available), then an Ethernet connection can be established using an Ethernet crossover cable. To establish an Ethernet connection, you must know the IP address of the control processor.
To establish a serial connection and log on to the SAN768B:
1. Verify that the SAN768B is powered on and that POST is complete by verifying that all power LED indicators on the port, control processor, and core switch blades display a steady green light.
2. Remove the shipping cap from the SERVICE port on the active CP. The active CP blade is indicated by an illuminated (blue) LED. Use the serial cable provided with the SAN768B to connect the SERVICE port on the active CP to a computer workstation.
Attention: The SERVICE port is intended primarily for the initial setting of the
IP address and for service purposes.
3. Access the SAN768B using a terminal emulator application (such as HyperTerminal in a Windows environment or TERM in a UNIX environment).
4. Disable any serial communication programs running on the workstation (such as synchronization programs).
5. Open the terminal emulator application and configure as follows:
26 SAN768B Installation, Service, and User’s Guide

Password was not changed. Will prompt again at next login until password is changed. swDir:admin>
7. (Optional) Modify passwords. Passwords can be 8 to 40 characters long. They must begin with an alphabetic character. They can include numeric characters, the dot (.), and the underscore (_). Passwords are case-sensitive, and they are not displayed when you enter them on the command line. To skip modifying the password, press Ctrl-C. For more information on passwords, refer to the Fabric OS Administrator’s Guide.

Configuring the SAN768B IP addresses

The SAN768B requires three IP addresses; one for the single logical switch in the SAN768B chassis (shown as SWITCH in the ipAddrShow command), and one for each of the CP blades (CP0 and CP1). These IP addresses are set using the
ipAddrSet command through the serial or Ethernet connection to the active CP
blade.
Notes:
1. The default IP addresses and host names for the SAN768B are as follows:
v 10.77.77.75 for CP0 (the CP blade in slot 6 at the time of configuration) v 10.77.77.74 for CP1 (the CP blade in slot 7 at the time of configuration)
Chapter 3. Starting and configuring the SAN768B 27
Page 56
2. The default password is "password."
Attention: Resetting an IP address while the SAN768B has active IP traffic such
as Fabric Manager, Fabric Watch, SNMP, or other applications can cause traffic to be interrupted or stopped. Changing the IP address causes a domain address format RSCN to be issued.
Follow these steps to configure the IP addresses for both CP blades (from the active CP blade):
1. Log in to the active CP as admin using the serial or Ethernet connection.
2. Set up the SAN768B IP address by entering the ipaddrset -sw 0 command at the prompt.
swDir:admin> ipAddrSet -sw 0
Enter the requested information at the prompts. Specify the -sw 0 IP address. There is no -sw 1 IP address.
The addresses 10.0.0.0 through 10.0.0.255 are reserved and used
Note:
internally by the SAN768B. External IPs cannot use these addresses either.
3. Set up the CP0 blade IP address by entering the ipaddrset -cp 0 command at the prompt.
swDir:admin> ipAddrSet -cp 0
Enter the requested information at the prompts.
4. Set up the CP1 blade IP address by entering the ipaddrset -cp 1 command at the prompt.
swDir:admin> ipAddrSet -cp 1
Enter the requested information at the prompts. The following is a sample IP configuration for the SAN768B (sw -0) and the two
CP blades (cp0 and cp1).

Committing configuration...Done. swDir:admin> reboot
5. Reboot the SAN768B by typing reboot at the prompt.
The serial port can be used to monitor error messages through a serial connection. It is not recommended as a command interface during normal operations. If this port is not going to be in ongoing use, remove the serial cable and protect the port from dust by replacing the shipping cap.

Establish an Ethernet connection

After using a serial connection to configure the IP addresses for the SAN768B, you can connect the active CP blade to the local area network (LAN) if desired.
Note: Connecting the CP blades to a private network/VLAN is recommended.
By establishing an Ethernet connection, you can complete the SAN768B configuration using either the serial session or a Telnet session, or through the graphical management interfaces: Web Tools and Fabric Manager. However, you must ensure that the SAN768B is not modified from other connections at the same time.
To establish an Ethernet connection to the SAN768B, follow these steps:
1. Remove the shipping plug from the Ethernet port on the active CP blade.
2. Insert one end of an Ethernet cable into the Ethernet port.
3. Connect the other end to an Ethernet 10/100 Base-T LAN. The SAN768B can now be accessed by remote connection using any of the
available management tools, such as Telnet, Web Tools, or Fabric Manager.
4. To complete any additional SAN768B configuration procedures through a Telnet session, log in to the SAN768B by Telnet, using the admin login. The default password is password.
Chapter 3. Starting and configuring the SAN768B 29
Page 58

Customize a switch name

The switch name of the SAN768B can be up to 15 characters long; can include alpha, numeric, and underscore characters; and must begin with an alpha character.
Changing the name causes a domain address format RSCN to be issued.
Note:
To customize the name, follow these steps:
1. Enter the switchName command with the new name in quotes.
2. Record the new name for future reference.

Set the Domain ID

Each switch in the fabric must have a unique Domain ID. The Domain ID can be set using the configure command. You can also allow the Domain ID to be automatically set. The default Domain ID for the SAN768B is 1.
To set the Domain ID, follow these steps:
1. Enter the fabricshow command to determine the already assigned Domain IDs.
2. Enter the switchdisable command to disable the SAN768B.
3. Enter the configure command.
4. Enter y at the Fabric parameters prompt:
5. Enter a unique Domain ID:
6. Complete the remaining prompts or press Ctrl+D to accept the other settings
7. Enter the switchEnable command to reenable the SAN768B.
swDir:admin> switchName "swDirector5" Committing configuration... Done. swDirector5:admin
Fabric parameters (yes, y, no, n): [no] y
Domain: (1..239) [1] 3
and to exit.

Verifying the PID mode and connecting to the fabric

Before connecting the SAN768B to the fabric, verify that the port identifier (PID) mode on the SAN768B matches the other switches in the fabric. This parameter must be set identically on all switches in the fabric. This parameter is set using the
configure command.
For information on PID mode, refer to the Fabric OS Administrator’s Guide. Before starting, also refer to “Managing cables” on page 9 for more information on how to organize and route cables to minimize potential problems with large numbers of fiber optic cables.
To connect the SAN768B to the fabric, follow these steps:
1. Add SFP transceivers and cables to the fibre channel ports, as required. The ports are color-coded to indicate which ones can be used in the same port
group for trunking. Trunking port groups can be up to eight ports. Trunk groups
30 SAN768B Installation, Service, and User’s Guide
Page 59
are displayed by shaded or nonshaded ports. The ports and cables used in trunking groups must meet specific requirements.
For a list of these requirements, refer to the Fabric OS Administrator’s Guide.
2. Position one of the SFP transceivers so that the key is oriented correctly to the port. Insert the transceiver into the port until it is firmly seated and the latching mechanism clicks.
Transceivers are keyed so that they can only be inserted with the correct orientation. If a transceiver does not slide in easily, ensure that it is correctly oriented. For instructions that are specific to the transceiver model, refer to the transceiver manufacturer’s documentation.
3. Position a cable so that the key (the ridge on one side of the cable connector) is aligned with the slot in the transceiver; then, insert the cable into the transceiver until the latching mechanism clicks.
Cables are keyed so that they can only be inserted with the correct orientation. If a cable does not slide in easily, ensure that it is correctly oriented.
4. Repeat step 1 on page 30 through step 3 for the remaining ports.
5. Organize the cables as required. For recommendations regarding cable management, refer to “Managing cables” on page 9.
6. Verify the SAN768B for switch and port status by entering the switchshow command.
The switchshow command provides detailed information about the SAN768B.
7. Verify fabric connectivity by entering the fabricshow command. The fabricshow command provides general information about the fabric.

Enabling software licenses

To determine which licenses are currently enabled, enter the licenseShow command.
Table 8. Example of viewing enabled licenses
swDir:admin> licenseshow AAbbccDDeeFFeeGG:
Web license Zoning license Extended Fabric license Fabric Watch license Performance Monitor license Trunking license Security license
In the example above, the license key is AAbbccDDeeFFeeGG. Make sure you keep a hardcopy of your license key in a secure location for emergency reference.
The 64-bit chassis ID is required to obtain and activate licenses for the SAN768B. The chassis ID is available through the licenseIdShow command.
Both the licenseShow and licenseIdShow commands must be entered through the active CP blade.
For information about activating licenses, refer to the Fabric OS Administrator’s Guide.
Chapter 3. Starting and configuring the SAN768B 31
Page 60

Backing up the configuration

Save all key configuration data for the SAN768B, including license key information, and upload it to a host for emergency reference. Routine backups of the configuration are recommended to ensure the current configuration is available if needed.
After all zoning configurations and other changes are complete, back up the configuration by entering the configUpload command at the prompt.
The configUpload command uploads the SAN768B configuration to the server so that it is available for downloading to a replacement SAN768B, if necessary.
An easy way to backup configuration information is to enable logging on your Telnet session and then running the following commands and saving the output in a file on a secure host. Once you enable logging, run the following commands:
v configShow v ipAddrShow v licenseShow v switchShow
hardcopy versions of key data such as passwords, license keys, and IP
Keep addresses. This is sensitive information and should be kept in a secure location.
Note: Passwords are not saved in the configuration file, and are not uploaded
during a configUpload. Password information should be saved in hardcopy in a secure location for emergency reference, subject to your security and password management policy.

avoid unintentional merging of fabrics. Before you can successfully configure FCIP tunnels, you must enable the ports. When the blade is first powered up, all port status LEDs will continue to flash amber. This is normal. Use the portCfgShow command to view the status of the ports. Use the portCfgPersistentEnable command to enable a port. Refer to the Brocade Fabric OS Administrator’s Guide and the Brocade Fabric OS Command Reference Manual for more information on these commands.
Perform the following to determine the status of a FR4-18i router blade:
1. The FR4-18i router blade must be installed in a SAN768B in order to be powered on.
2. Power is supplied to the blade once it is installed in the SAN768B and the power switch on the blade is moved to the On position. The router blade runs POST by default each time it is powered on. It typically requires from 1 to 3 minutes to boot and complete POST.
3. Log in to the SAN768B as admin and run the slotShow command. The status of the FR4-18i blade is displayed in the output.
Chapter 4. Monitoring system components 37
Page 66
4. Run the errShow command to determine if any errors detected during POST are written to the system log. For information about this command, see the Fabric OS Command Reference Manual. For information about specific error messages, see the Fabric OS System Error Message Reference Manual.
5. Check the LED indicators on the power supply (see Figure 13.) The LED patterns may temporarily change during POST and other diagnostic tests; for information about how to interpret the LED patterns and verify that all components are healthy, refer to Table 11 on page 39.
6. If any of the LEDs appear to indicate a problem, verify that the LEDs are not set to "beacon" (this can be determined through the switchShow command or Web Tools). For information about how to turn beaconing on and off, see the Brocade
Fabric OS Administrator’s Guide or the Brocade Web Tools Administrator’s Guide. Follow the recommended action for the observed LED behavior, as listed
in Table 11 on page 39.

Removing and installing port blades

This section describes how to remove and install port blades.
Attention: A filler panel should be removed only when being replaced with a port
blade, or a filler panel. Any slot that is not occupied by a blade should be occupied by a filler panel to ensure correct cooling of the chassis and protection from dust.
Slots are numbered from 1 through 12, from left to right when facing the port side of the SAN768B. Port blades can be installed in slots 1 through 4 and 9 through 12.
Chapter 5. Removing and installing components 53
Page 82

Time and items required

The installation procedure for each port blade takes less than 10 minutes. The following items are required for the blade and filler panel installation:
v ESD (electrostatic discharge) grounding strap v Workstation computer v Installation blade or filler panel v Phillips screwdriver v Small form-factor pluggable (SFP) or extended form-factor pluggable (XFP,
FC10-6 blade only) transceivers (as needed)
v Optical cables (as needed)

Removing a port blade

To remove a port blade, do the following:
Attention: Follow ESD precautions.
1. Remove the chassis door. (See “Removing and installing the chassis door” on page 51.)
2. A failed port or application blade can be identified by inspecting the LEDs on the front panel of each blade. Check the power LED, status LED, and port status LED to identify any possible problems. See Figure 14 on page 41 to Figure 13 on page 38 for LED locations.
3. Establish a Telnet or console session. Before installing a blade, establish a Telnet or console connection to determine
a failure and verify operation after installation. Use the switchShow command to view the status of blades.
4. Check for adequate cable slack. Ensure there is plenty of cable slack to remove a blade without cable obstruction.
5. Ensure that the part number on the unit being installed matches the replacement part number. The chassisShow command displays information about the blades, including part numbers, serial numbers, and additional status.
6. Ensure that traffic is not flowing through the blade (port status LED should be off) prior to disconnecting cables.
Before removing any cables from a blade, note the cable order (identify
Note:
each cable by its physical port). If multiple blades are being installed, install one blade at a time.
7. Ensure that traffic is not flowing through the blade.
8. Disconnect all cables and SFP or XFP transceivers from the blade.
9. For FC8-16, FC8-32, FC8-48, and FC10-6 port blades: Adjust the ejectors to the open position. (See Figure 23 on page 55.) Unscrew the two thumb screws from the top and bottom ejectors on the blade using the Phillips screwdriver. Unscrew the top thumb screw until it pops out. This initiates a hot-swap request.
10. Wait for the power LED to turn off in response to the hot-swap request before removing the blade.
11. Open the ejectors. Pull the blade out of the chassis using the ejectors.
12. If the blade is not being replaced by another blade, install a filler panel. See “Removing and installing port blade filler panels” on page 56.

Removing and installing a control processor blade (CP8)

This section describes how to remove and install a control processor (CP8) blade. Each SAN768B has two CP8 blades located in slot 6 and slot 7.
If the new CP blade does not have the same firmware as the active CP
Note:
blade, you must upgrade the new blade to the same firmware version.
Chapter 5. Removing and installing components 57
Page 86
Firmware downloads require that Ethernet connections be made to both CP blades. Procedures for loading firmware are described in the Brocade Fabric OS Administrator’s Guide.

Time and items required

The installation procedure for the CP blade takes approximately 30 minutes. The following items are required for the CP blade installation:
v ESD (electrostatic discharge) grounding strap v Workstation computer v Serial cable v IP address of an FTP server for backing up the SAN768B configuration v Phillips #2 screwdriver v Replacement CP blade. SAN768B requires the CP blade (CP8).

Verifying the necessity of installation

Confirm that you need to install the CP blade. The following events might indicate that a CP blade is faulty:
v The status LED on the CP blade is lit amber, or the power LED is not lit. v The CP blade does not respond to Telnet commands, or the serial console is not
available.
v The slotShow command does not show that the CP blade is enabled. v The haShow command indicates an error. v The clock is inaccurate, or the CP blade does not boot up or shut down normally. v Any of the following messages display in the error log:
“Slot unknown” message relating to a CP slot CP blade errors or I2C timeouts FRU: FRU_FAULTY messages for a CP blade Configuration loader messages or “Sys PCI config” messages Generic system driver messages (“FABSYS”) Platform system driver messages (“Platform”) EM messages that indicate a problem with a CP blade Function fail messages for the CP master
more information about error messages, refer to the Fabric OS Message
For Reference.

Recording critical SAN768B information

Back up the SAN768B configuration before you replace a CP blade. Refer to the
Fabric OS Administrator’s Guide for backup information.
To record critical SAN768B information, do the following:
1. Login to the functioning CP blade as admin, using either a Telnet or a serial console connection.
2. Type haShow to determine which CP blade is active:
swDir:admin> haShow Local CP (Slot 7, CP1) : Active Remote CP (Slot 6, CP0) : Standby, Healthy HA Enabled, Heartbeat Up, HA State Synchronized
58 SAN768B Installation, Service, and User’s Guide
Page 87
3. Enter all remaining commands from the serial console for the active CP blade, unless otherwise indicated. For more information about commands, refer to the Fabric OS Command Reference.
4. If the functioning CP blade is performing as the active CP blade, go to step 5. If the faulty CP blade is performing as the active CP blade, failover the blades:
a. Login to the faulty CP blade as admin, using either a Telnet or a serial
console connection. If you connect successfully to the faulty CP, continue to step b. If you cannot connect to the faulty CP, remove the faulty CP blade for repair
as follows:
1) Turn the CP blade off and notify the SAN768B of a hot swap request by sliding the slider switch in the top ejector down to the off position (see Figure 25 on page 61).
2) Wait until the active CP LED on the functioning CP blade is lit. Remove the CP blade.
b. Type haFailover. The functioning CP blade becomes the active CP blade. c. Wait until the status LED on the functioning CP blade is no longer lit. d. Type haShow from the functioning CP blade (the new active CP blade) to
verify the failover. This is an example of failing over a CP blade:
Fabric OS (cp1)
cp1 login: admin Password: swDir:admin> hashow Local CP (Slot 7, CP1): Active Remote CP (Slot 6, CP0): Standby, Healthy HA enabled, Heartbeat Up, HA State synchronized swDir:admin> hafailover Local CP (Slot 7, CP1): Active Remote CP (Slot 6, CP0): Standby, Healthy HA enabled, Heartbeat Up, HA State synchronized
Warning: This command is being run on a redundant control processor(CP) system. If the above status does not indicate ’HA State synchronized’, then the CPs are not synchronized and this operation will cause the active CP to reset. This will cause disruption to devices attached to both switch 0 and switch 1 and will require that existing Telnet sessions be restarted. To reboot a single logical switch on this system, use the switchreboot command while logged in to that logical switch.
Are you sure you want to fail over to the standby CP [y/n]? swDir:admin> haShow Local CP (Slot 7, CP1) : Standby, Healthy Remote CP (Slot 6, CP0) : Active HA Enabled, Heartbeat Up, HA State Synchronized
5. Type firmwareShow to note the firmware version of the active CP blade.
6. Type haDisable from the active CP blade to prevent failover or communication between the CP blades during the replacement.
7. Logged into the active CP, use the configUpload command to upload the SAN768B configuration to a specified FTP server. Enter information at the prompts.
This is a sample of backing up the configuration files:
Chapter 5. Removing and installing components 59
Page 88

Removing a control processor blade (CP8)

The SAN768B continues to operate while a CP blade is being installed if the redundant CP blade is active and a failover does not occur. Yo u can prevent failover by entering the haDisable command.
To remove a CP blade, do the following:
1. Remove the chassis door. (See “Removing and installing the chassis door” on page 51.)
2. Login to the active CP as the admin user. Yo u can use a serial cable or Telnet, Web Tools, or Fabric Manger. Determine which CP is active using the haShow command or view the active LED on the front of the CP.
3. If the faulty CP is the active CP, issue the haFailover command. Wait until the failover has completed. Use the haShow command to verify the CPs are synchronized and the failover is complete.
4. Power off the blade by sliding the slider switch in the top ejector down to the off position (see Figure 25 on page 61).
5. Disconnect all cables from the faulty (standby) CP.
6. Unscrew the thumb screw from both ejectors using the Phillips screwdriver.

Removing and installing an FR4-18i router blade

This section describes how to remove and install an FR4-18i router blade in the SAN768B. Yo u can install up to two router blades in any of slots 1-4 and 9-12. To ensure proper cooling, install only one router blade in each slot grouping. See Figure 13 on page 38, for blade removal and installation, as an example of how to remove a router blade.
Attention: Follow these precautions for all procedures in this section to avoid
damaging the router blades or chassis:
v Wear a grounded ESD strap when handling the router blade. v To ensure adequate system pressure for cooling purposes, leave the faulty router
blade in the slot until you are ready to perform the installation or replacement procedure.
v Do not force the router blade into the chassis. If the blade does not slide in
easily, ensure that it is correctly aligned inside the rail guides before continuing. Installing a router blade with incorrect alignment can damage both the chassis and the router blade.
v Hold the router blade by the edges of the metal pan. Do not use the ejectors to
hold a router blade.
v Disassembling any part of a router blade voids the part warranty and regulatory
certifications. There are no user-serviceable parts inside the router blade.

Time required

Approximately 10 minutes

Items required

v ESD (electrostatic discharge) grounding strap v Workstation computer v Replacement router blade v Phillips screwdriver

Removing a router blade

A failed router blade can be identified by inspecting its LEDs and by using CLI commands to verify status. Refer to Figure 13 on page 38, for a description of the router blade LEDs. See the Fabric OS Administrator's Guide for information about how to check the status of hardware components using the CLI.
Perform the following steps to remove a router blade:
1. Check the power LED, status LEDs, port speed LEDs, and port status LEDs to identify any possible problems with the router blade.
66 SAN768B Installation, Service, and User’s Guide
Page 95
2. Establish a Telnet or console session before removing an router blade to determine a failure and verify operation before removal. Use the switchShow command to view the status of blades on the SAN768B.
3. Check for adequate cable slack. Make sure there is plenty of cable slack to remove a router blade without
optical, power, or Ethernet cable obstruction. Refer to “Managing cables” on page 9 for cabling guidelines.
4. Ensure that you have the proper spare part (filler panel or replacement router blade).
Make sure that the part numbers match for the unit being replaced. The
chassisShow command displays information about the router blades,
including part numbers, serial numbers, and additional status.
5. Ensure that traffic is not flowing through the router blade (all port status LEDs should be off) prior to disconnecting cables.
Before removing any cables from the faulty router blade, label the
Note:
cables or make a note of the cable order by identifying each cable by the physical port it attaches to. This will reduce confusion when you reattach cables. If two router blades are being replaced, install one blade at a time.
6. Disconnect all cables and remove the SFP transceivers from the Fibre Channel and GbE ports as required.
7. Turn the router blade off by sliding the on/off switch in the top ejector down, to the off position (see 3 in Figure 13 on page 38 as an example). This initiates a hot-swap request.
8. Wait for the power LED to turn off in response to the hot-swap request before removing the router blade.
9. Unscrew the captive screws from the top and bottom ejectors on the blade using a Phillips screwdriver.
10. Lever both ejectors open simultaneously to approximately 45 degrees, and pull the router blade out of the chassis.
11. If the blade is not being replaced by another router blade, install a filler panel
to ensure correct cooling of the chassis and protection from dust. See “Installing a filler panel” on page 57 for instructions.

Installing a router blade

You can install up to two FR4-18i router blade in slots 1–4 or 9-12. If you are installing two router blades, install one in one of the slots 1–4, and the other in one of the slots 9-12 to maintain proper cooling. The control processor (CP) blades occupy slots 6 and 7. The core switch (CR) blades occupy slots 5 and 8. Any slots that are not occupied by a port blade, router blade, or CP blade must have a filler panel installed to ensure proper cooling of the chassis and protection from dust. If you are performing a new installation of a router blade, you must either remove the filler panel or a port blade from the slot where you will install the router blade.
Attention: All ports on the router blades are by default, persistently disabled to
avoid unintentional merging of fabrics. Before you can successfully configure FCIP tunnels, you must enable the ports. When the blade is first powered up, all port status LEDs will continue to flash amber. This is normal. Use the portCfgShow command to view the status of the ports. Use the portCfgPersistentEnable command to enable a port. Refer to the Fabric OS Administrator’s Guide and the
Fabric OS Command Reference Manual for more information on these commands.
Chapter 5. Removing and installing components 67
Page 96
To install an FR4-18i router blade, complete these steps:
1. Enter the chassisConfig command, and verify that it is in mode 5. If the chassisConfig mode is 5, this step is complete. If not, enter the chassisConfig
5 command.
Attention: Changing the chassisConfig mode requires a reboot, and is
disruptive to SAN768B operation.
2. Select an empty slot from slots 1-4 or 9-12 to install the router blade.
3. Make sure the latches on the router blade are unscrewed and open. If you are performing a new installation of a router blade, you must either remove the filler panel or a port blade from the slot where you will install the router blade.
4. Orient the router blade so that the ports are at the front of the chassis and the router blade power switch is at the top.
5. Make sure the latches on the router blade are unscrewed and open.
6. Slide the router blade into the open slot until it is fully seated.
7. Close the latches and tighten the screws on the latches.
8. Power on the blade using the power switch at the top of the blade. Keep the blade in an offline (disabled) state until the ports are configured.
The router blade will begin POST as soon as the power is turned on.
Note:
After POST is complete the firmware version on the blade will autolevel with the firmware version on the active CP.
9. Verify that the blade power and blade status LEDs are green after the blade has completed booting up.
10. Verify the installation. For information about how to check the status of hardware components using the CLI, See the Fabric OS Administrator’s Guide.
11. Log into the SAN768B as the admin user.

Configuring FCIP and Fibre Channel routing services and enabling the ports

Refer to the Fabric OS Administrator’s Guide or the Web Tools Administrator’s Guide for detailed information on configuring the router blade. The following steps
provide only a brief overview of the procedure.
1. Verify that the FR4-18i router blade is in an offline (disabled) state until the ports
are configured.
Attention: The ports on the FR4-18i router blade are initially set to
persistently disabled. They will flash amber until they are enabled. This is normal. If you want to use the FC ports and EX_Ports, you must configure the Fibre Channel Routing Services feature prior to enabling the ports.
2. Use the portCfgPersistentEnable command to enable standard E_ports or
F_ports.
The GbE ports can only be used once you have configured FCIP and
Note:
enabled VE_Ports. See the Fabric OS Administrator’s Guide for detailed instructions on configuring the Fibre Channel Router ports and GbE ports on the FR4-18i router blade.

Cabling the FR4-18i router blade

Complete the router blade configuration by installing the SFP transceivers in the Fibre Channel and GbE ports.
68 SAN768B Installation, Service, and User’s Guide
Page 97
1. Install the SFP transceivers in the Fibre Channel and GbE ports, as required. Refer to “Installing and removing FC transceivers in a port blade” on page 76 for more detailed instructions.
2. Remove the rubber plugs from the ports to be used.
3. Position a transceiver so that it is oriented correctly and insert it into a port until it is firmly seated and the latching mechanism clicks. For instructions specific to the type of transceiver, see the transceiver manufacturer’s documentation.
The transceivers are keyed to ensure correct orientation. If a transceiver
Note:
does not install easily, ensure that it is correctly oriented.
4. Repeat Steps 2 and 3 for the remaining ports, as required.
5. Connect the cables to the transceivers.
Attention: A 50-micron cable should not be bent to a radius less than 2
inches under full tensile load and 1.2 inches with no tensile load. Tie wraps are not recommended for optical cables because they are easily overtightened.
6. Orient a cable connector so that the key (the ridge on one side of connector) aligns with the slot in the transceiver. Then, insert the cable into the transceiver until the latching mechanism clicks. For instructions specific to cable type, see the cable manufacturer’s documentation.
7. Repeat Step 6 for the remaining cables as required.
8. Check the LEDs to verify that all components are functional. For information about LED patterns, see “FR4-18i router blade” on page 37.
9. Log in to the SAN768B as admin.
10. Verify the correct operation of the FR4-18i router blade ports by typing the
switchShow command from the SAN768B command prompt. This command
provides information about switch and port status. Once the FR4-18i router blade is installed and fully configured in a SAN768B,
the switchShow command displays 32 Fibre Channel ports (port numbers 0 through 31) and 2 GbE ports. The first 16 Fibre Channel ports are physical ports on the FR4-18i router blade, Ports 16-23 are virtual ports associated with the GE0 physical GbE link and ports 24-31 are virtual ports associated with GE1 physical GbE links. The GbE ports are displayed as ge0 and ge1 and are not assigned port numbers or area numbers.
