This post introduces how to configure zones of a Brocade FC switch, reset its password, and also common configuration operations with Brocade, Cisco, and QLogic switches.
[Configuring zones of a Brocade FC switch]
Step 1: Connect to a switch
Connect a PC to a management network port of a Brocade FC switch using a network cable. The switch default IP address is 10.77.77.77, the switch subnet mask 255.255.255.0, the default user name admin, and the password is password (all characters are lowercase.)
Step 2: Change the switch name
Click Switch Admin, and type a new name for the switch in Switch Name and Domain ID of the Switch tab. NOTE: The domain ID of each switch must be different if they are cascaded.
Then click Apply at the lower right corner.
Step 3: Change the IP address of the FC switch.
Click the Network tap, and type a new IP address, a new subnet mask, and a gateway IP in the IPv4 as shown in the following figure.
Drag the scroll box on the right side to the bottom and click Apply.
Then the PC is disconnected from the FC switch. Connect the PC to another FC switch and repeat Step 1 through Step 3 until the information of the two switches is changed.
Step 4: Configure Zones
Configure the IP address of the PC on the same network segment as that of the switch and connect the PC to the switch. Log in to the switch and click Zone Admin.
Click the Zone Config tab and click New Zone Config. Enter a new config name such as Config1 in the Create New Config box that is displayed and click OK.
Click the Zone tab and New Zone. Enter a new zone name such as P570_S2600 in the Create New Zone box that is displayed and click OK. NOTE: Only underscores can be used to connect characters in a zone name.
In the Member Selection List on the Zone tab, choose Ports & Attached Devices > 1 (a switch name). Select a port to be added in the Zone and click Add Member. Make sure that the port is displayed on the right side of the window.
Repeat the Step 4 until all define-required zones and zone members are defined.
Step 5: Enable defined configurations
Click Zone Config, and select all new defined zones on the left side. Click Add Member to add these zones to the zone config. Make sure that all new defined zones are added to the Zone Config Member box.
Click Save Config. A dialog box is displayed. Click Yes.NOTE: All the information about zone configurations is saved to the configuration file Config1, but the configuration file is not enabled.
Click Enable Config and select Config1 in the dialog box that is displayed to enable the configuration file.
A dialog box is displayed. Click Yes
Check the information bar at the lower left corner. When the Successfully committed the changes to the fabric is displayed, the newly configured information takes effect.
Check the information Enabled Zone Config: at the lower right side. When the information changes to Enabled Zone Config: Config1, the configuration file is successfully enabled and takes effect.
NOTE: Information about when to enable the configuration file. When the configuration file for a switch is enabled, the entire fabric encounters instant intermittent disconnections, but the enabling process can still be complete online. However, if a database with intensive read and write operations is used, the database cannot tolerate intermittent disconnections shorter than 0.3 seconds.<0}
[Resetting the password of a Brocade FC switch]
1. Use user root to recover the initial password of user admin.
Reset the password for a Brocade 300 SAN Switch. Let's take an HP StorageWorks 8/8 SAN Switch as an example. 8 of its 24 ports are activated. The switch is actually a Brocade 300 SAN Switch with the HP brand, including its delivery-attached CD-ROM.
The default user name and password of a Brocade 300 SAN Switch are admin and password. As the user name and its password have been changed, it is necessary to reset the switch. One way to reset the switch is to run commands using a cable to connect through the console port, because there is no reset button in the switch.
The OS of the Brocade 300 uses Linux 2.6 kernel. The administrative account with the highest permission is user root. Use user root to reset the switch's password.
swd77 login: root
Password: fibranne
After using the account to log in, you find the following information:
Disclaimer for Root and Factory Accounts Usage!
This Fibre Channel switch is equipped with Root and Factory accounts
that are intended for diagnostics and debugging purposes solely by
the Equipment vendor's trained engineers. Improper use of the
functionality made available through the Root or Factory account could
cause significant harm and disruption to the operation of the SAN fabric.
Your use of the functionality made available through the Root or Factory
account is at your sole risk and you assume all liability resulting from
such use. The Equipment vendor shall have no liability for any losses
or damages arising from or relating to the use of the Root or Factory
account (and the functionality enabled thereby) by anyone other than
the Equipment vendor's authorized engineers.
Proceeding with the usage of this switch as the Root or Factory user
explicitly indicates your agreement to the terms of this disclaimer.
Please change passwords for switch default accounts now.
Use Control-C to exit or press 'Enter' key to proceed.
Use Control-C to exit. If you press Enter to proceed, all account passwords are reset with the following information:
Warning: Access to the Root and Factory accounts may be required for
proper support of the switch. Please ensure the Root and Factory
passwords are documented in a secure location. Recovery of a lost Root
or Factory password will result in fabric downtime.
for user - root
Changing password for root
Enter new password:
Password unchanged.
passwd: Authentication token manipulation error
Please change passwords for switch default accounts now.
for user - factory
Changing password for factory
Enter new password:
Password unchanged.
passwd: Authentication token manipulation error
Please change passwords for switch default accounts now.
for user - admin
Changing password for admin
Enter new password:
Password unchanged.
passwd: Authentication token manipulation error
Please change passwords for switch default accounts now.
for user - user
Changing password for user
Enter new password:
Password unchanged.
passwd: Authentication token manipulation error
After logging in, run the passwddefault command to set a password to the factory default.
swd77:root> passwddefault
Password policies are already set to default.
All account passwords have been successfully set to factory default.
swd77:root>
2. Use the Boot PROM to recover a password.
When you forget the password of user admin and cannot log in using user root, you can change the OS of the switch to a single-user mode to initialize the password.Connect the serial port of your PC to the switch and then restart the switch. When press ESC key within 4 sec is displayed, press the ESC key within 4 seconds. The following options are displayed:
- 1) Start system
Used to reboot the system.
- 2) Recover password.
Used to generate a character string for your support provider to recover the Boot PROM password.
- 3) Enter command shell.
Used to enter the command shell, to reset all passwords on the system.
2. Choose 3，Command Prompt shell
The system is coming up, please wait...
Checking system RAM - press any key to stop test
01a00000
System RAM check terminated by keyboard
System RAM check complete
Press escape within 4 seconds to enter boot interface.
1) Start system.
2) Recover password.
3) Enter command shell.
Option? 3
4. Run the setenv OSLoadOptions single command.
5. Run the boot command and sh-2.04# is displayed.
6. Run the mount -o remount,rw,noatime / command.
7. Run the mount /dev/hda2 /mnt command.<0}
8. Run the /sbin/passwddefault command to initialize the password.<0}
9. Restart the switch and run the reboot-f command.<0}
3. Run the printenv command.
