MSA1050 admin密码忘记如何恢复

方法1：就是日常通过串口线使用临时账户登录进行修改的办法
If the end user has a second MSA 2040/1040/P2000 try the following procedure:
1. Remove both controllers from the system with the lost password. Take both controllers to the secondary site/array location.
2. At the secondary site - perform the following actions during a down time or period of low host IO.
3. On the secondary array - log into SMU, disable Partner Firmware Upgrade (PFU), remain logged into SMU while performing the next steps.
4. On the secondary array - shutdown the B controller. Once the controller is fully down remove the good controller. Label it and set aside.
5. Insert a controller from the affected system (it does not matter which controller A/B). Allow the controller to boot fully, this may take 15 minutes. Please give the controller plenty of time to power up and copy the configuration from the A controller.
6.In SMU check the A controller and confirm the user settings. Check and verify the password is correct by using CLI to log into the B controller IP address. The password should now be set to the same user settings as the A controller. We cannot have two different passwords on the two controllers. We will need to wait until you return to the original array to change the settings.
7. Once the password has been confirmed properly shutdown the B controller. Once the controller has powered down repeat steps 5-step7.
8. Once both controllers have been reset insert the original B controller. After the controller has powered on enable PFU.

Once back to the original array you may insert both controllers and power on the system. It does not matter which controller goes into which slot. The controllers should come up with the credentials from the secondary site. Log into the system and confirm all settings such as users, IP addresses, and any other settings configured.
方法2：同时更换2个控制器，密码是存放在控制器中，而不是背板中
The option is to replace both controllers at the same time. We will need to power down the array completely by removing all power cords from all enclosures. Allow 10-15 minutes for the controllers to finish flushing the cache. Once the cache LED has stopped flashing on the controllers. Remove both controllers and replace with two new controllers. DO NOT swap the Compact FLASH cards between the old and new controllers. The new Compact Flash cards should be in the new controllers and installed in the system or we will generate a Signature Mismatch on the Vdisks. When you power back on the system will come back up with default settings for most of the user set preferences. We will need to reset some configuration details but we should now be able to log into the system.
Please be sure that both controllers need to be replaced at the same time. This is the critical step. If one controller is replaced at a time the new controller will copy over the configuration from the surviving controller. So the problem will propagate from the old controller to the new controller and you will not resolve the issue.
NOTE: Only same model of MSA to be tried for interchange of controllers. This should not be attempted between different model of MSA.© Copyright 2015 Hewlett-Packard Development Company, L.P.
