Information in this document applies to any platform.

Symptoms

When carrying out configuration changes in a Sun Storage 2500, 2500-M2 or 6000 Array using Sun Storage Common Array Manager (CAM), CAM might return the error message "The operation cannot be completed because you did not provide a valid password" if you use the browser user interface (BUI), or "Authentication failed - incorrect password" if you use the command line (CLI).

Example when using the CLI:

bash-3.2# service -d <arrayname> -c reset -t t85bat1
Executing the reset command on st2540-tvp540-d
Completion Status: Authentication failed - incorrect password
bash-3.2#

Example when creating a new volume in the BUI:

The volume could not be created. The operation cannot be completed because you did not provide a valid password. Open the Storage Systems folder in the left hand navigational tree, click on the Administration folder, then click on Manage passwords and provide a valid Storage System password.

Cause

It is first important to understand the different passwords associated with a Sun Storage 2500, 2500-M2 or 6000 Array. Please refer to <Document 1012351.1> Passwords Associated with Sun Storage RAID Arrays.

By default all the new Storage Arrays are delivered with no array password, which means that it is blank.

An array password provides access to an array. When you set the password, the management software stores an encrypted copy of the password in its array registration database locally and in the array metadata (DACstore). Thereafter, the management software can perform modification operations on the array without a password challenge.

Multiple management hosts can access a single array. Each management host has its own instance of management software, each of which has its own array registration database. For the management software to perform modification operations on an array, the password stored in the array registration database locally for that instance of the management software must match the password stored on the array metadata.

You can change the array password at any time. When you change the password on one management host, only the array registration database used by that management host is updated with the changed password. Before another management host can perform modification operations on that array, the array registration database for that management host must also be updated with the new password.

You may also need to update the password stored in the array registration database if the array was registered without a password or with an incorrectly typed password.

If the password stored in the array registration database does not match the array password, an error message displays as described above.

Solution

If you do not remember the array password, please refer to <Document 1011201.1> How to Reset the Array Password on a Sun Storage[TM] RAID Array in order to reset the password and synchronize CAM.

If you remember the array password and you want to synchronize CAM, please follow the instructions in the section entitled "Changing the Array Password" on printed page 37 of the document Sun Storage Common Array Manager - Array Administration Guide for your version of CAM in Disk Device Software Documentation.
