ibm光纖交換機
具有高可用性技術,高級虛擬化技術方面,簡化管理方案,技術服務等優勢，那么偶爾丟了初始密碼怎么辦？要怎么恢復？今天廈門耐誠小編就教大家一個ibm光纖交換機恢復密碼的辦法。
在IBM 系列光纖交換機中一共存在下列用戶：
用戶名初始密碼
adminpassword
rootfibranne
factory
user
一般我們使用admin用戶進行Zone的劃分以及日常管理。
如果不慎將admin用戶密碼忘記：
1）可以用root用戶登陸，然后使用 #passwd admin 命令將密碼更改回來；
2）如果連root密碼也被改了，那么按如下步驟恢復：
1. Connect serial cable to switch (test it before you reboot your
switch).
2. reboot the switch and press ESC key within 4 seconds at boot message
“press ESC key within 4 sec….”
3. Menu will appear, go to Command Prompt shell (mostly option 3)
4. Enter the command:
#mount -o remount,rw,noatime /
5. Enter the command:
mount /dev/hda2 /mnt
6. Enter the command:
#passwddefault
or
#passwd admin (to reset admin password only)
7. #reboot -f
***********************************************************************
If you fail at step 5, Enter the command:
#printenv
and look for “OSRootPartition” param, the second partition should be
mounted (usually hda2)
***********************************************************************
3）如果以上兩個步驟均不成功，這樣就只好聯系brocade/IBM了：
a. 記下該switch的WWN
b. 將這個信息發給support@brocade.com
c. 會得到passwd reset的image file
d.
用一臺機器通過串口連switch，并用這臺機器和switch的lan口連接，之后就按照brocade回復的郵件里面的操作來進行就可以了。（詳見附錄B）
附A：
FOSV2.6 password recovery:
1. Open a serial connection to the switch. Use Windows HyperTerminal in
Windows or Kermit in UNIX.
2. Power cycle the switch.
3. From the serial console window, press any key when the message Press any
key to stop auto-boot... This will display the boot prompt.
4. At the [VxWorks Boot] prompt, type c and press enter to start changing
the boot parameters in order to boot from the network.
附B：
Recovering from a Forgotten Password on Switch
If you forget your password on a switch, perform the following:
1. Contact Brocade’s Customer Support to acquire the Password
Recovery firmware version. The contacts are:
? Telephone: 1-888-283-4273
? Web site: www.brocade.com
? Email address: support@brocade.com
You will need to provide the WWN of your primary FCS switch.
To perform password recovery, you must set up boot parameters on your
switch, using a serial connection, to perform a netboot. The Password Recovery
firmware is used only to reset the passwords to their defaults, change the
firmware to boot from the flash again, and freeze the switch until it’s manually
rebooted. No other switch functions can be performed by the password recovery
firmware.
If you do not have a serial connection, contact Brocade’s Customer
Support.
2. Open a serial connection with the switch.
Use Windows HyperTerminal in Windows OS or the Kermit program in Unix.
3. Power cycle the switch.
If your switch is on, turn it off and on. If your switch is off, turn it
on.
4. From the serial prompt window，
press any key when you see the message:
Press any key to stop autoboot....
This process gives you access to the boot prompt.
5. When you see the prompt:
[VxWorks Boot]
Enter c to start changing the boot parameters to boot from the network.
At each question, the default answer will be displayed. To change it, enter
the new value next to the default.
The following example shows a typical message that appears from the
console.
Example:
6. Enter @ at the [VxWorks Boot] prompt to start booting the
Password Recovery version of the firmware from the network.
EXAMPLE：
The firmware will reset the passwords to defaults.
The following example shows a typical message that appears from the
console.
Attaching network interface fei0...done.
Attaching network interface lo0...done.
MyHostMachine is alive.
Loading...4173912 + 339516 + 423108

gateway inet (g) :123.456.789.1
user (u) :jsmith
flags (f) :0x8
target name (tn) :switch
Passwords have been reset.
7. You need to reset your boot parameters back to their default
settings so that the switch will boot from flash. Repeat steps 3 and
4.
8. When you see the prompt:
[VxWorks Boot]
Enter c to start resetting the boot parameters back to their default
settings.
9. Remove the fields that you added in step 5 by entering a dot (.)
to clear the fields and pressing Enter.
The boot parameters have returned to their original settings.
10. Power cycle the switch so that the original firmware is
re-loaded from flash and normal operations resume.
