Dealing With Managed System Passwords

Dealing With Managed System Passwords:

There are two sets of the passwords when you are dealing with the power machines.These are very important when you are adding  managed systems to the HMC ( Hardware Management Console).

And those passwords are 
  •  Server (HMC Access) Password
  •  Advanced System Management (ASM) Password

1) Advanced System Management (ASM) Password:

Advanced System Management Interface (ASMI) is a graphical interface that is part of the service processor firmware. The ASMI manages and communicates with the service processor. The ASMI is required to set up the service processor and to perform service tasks, such as reading service processor error logs, reading vital product data, and controlling the system power. There will be seperate password for  ASM to access it.

The ASMI might also be referred to as the service processor menus

2) HMC Access password:

The HMC Access password is a managed system password used to authenticate the HMC to the server. It is one of three managed system passwords set when the system is first installed. The three user IDs whose passwords must be set are admin, general, and HMC (also referred to as HMC Access). 

There is no default password for the HMC ID. The HMC access password is initially clear and the user is prompted to set a password the first time a HMC connects. After setting or entering the HMC access password once, the HMC caches the password locally. It is important to record the password for future use because the password will need to be re-entered if a new or scratch-installed HMC is used.

If the HMC password has not been set, the HMC connection will go to the state Pending Authentication - Password Update Required. The user is prompted to set an initial password for each of the three accounts in the Update Password Pending Authentication window.

If the window does not appear, ensure the user is logged into the HMC as hscroot: Pre-version 7 HMC, right click on the server entry on the console. The window for setting passwords opens. Set the passwords as directed. On Version 7 or later, select the server. Under tasks, select the Update password task then enter the passwords.

Setting Passwords for ASM & HMC Access

When you are trying to add managed system,If you received the message Authentication Pending, the HMC prompts you to set the passwords for the managed system.

If you did not receive the message Authentication Pending, complete the following steps to set the passwords for the managed system.

Updating your server(HMC Access) password

To update your server password, do the following:
  1. In the navigation area, select the managed system.
  2. In the Tasks area, click Operations.
  3. Click Change Password. The Update Password window opens.
  4. Type the required information and click OK.

Updating your Advanced System Management (ASM) general password

Note: The default password for the general user ID is general, and the default password for the administrator ID is admin.
To update your ASM general password, do the following:
  1. In the navigation area of the HMC, select the managed system.
  2. In the Tasks area, click Operations.
  3. Click Advanced System Management (ASM). The Launch ASM Interface window opens.
  4. Select a Service Processor IP Address and click OK. The ASM interface opens.
  5. On the ASMI Welcome pane, specify your user ID and password, and click Log In.
  6. In the navigation area, expand Login Profile.
  7. Select Change Password.
  8. Specify the required information, and click Continue.

Resetting Passwords:

1) ASM Administrator Access Password Reset:

To reset the administrator password, contact an authorized service provider.

2) HMC Access Password Reset:

If the HMC Access password has already been set and an incorrect password is entered, the state is Failed Authentication - Incorrect password. The HMC will prompt the user to enter the HMC access password. After several invalid password attempts, the connection will go into the Failed Authentication - Firmware Password Locked state (0803-0001-00000203). The user must wait five minutes or reset the password in ASMI before any further attempts can be made.

To reset a lost HMC Access password, you should use one of the following methods:

oIf the admin password is known, use ASMI to reset the HMC password.  Refer this link .
Note: The default password for user admin is admin.
oIf the admin password is lost, contact an authorized service provider for information on how to reset both passwords. There are two methods available for the service provider:
- Provide a temporary login for user celogin
- Reset passwords and network settings using the FSP dip switches.

For further information, you should refer to Set Passwords for the Managed System , Reset the Advanced System Management (ASM) administrator password section  refer this link Database 'DCF Technotes (IBM i)', View 'Products', Document 'Changing an ASM Password'.

Resetting HMC Access Password  ( if ASMI  admin password known):

From the Advanced System Management (ASM) login screen, type the user ID and password, and click the Log in button or press the Enter key. 

Note: Ensure the desired system is selected.

Expand Login Profile, select Change Password, and then select the User ID you want to change.

Note: The Current password field indicates the user signed into ASM (not necessarily the User ID being changed).

Note:If the admin password is lost, contact your service provider for a temporary celoginprofile that can be used to reset admin.
