Assigning Credentials

When configuring an agent to monitor a storage device, you need to assign a credential. Here are some typical scenarios:

•
A storage device has a unique account and password. Create a credential to contain the account and password and assign it to this device only.
•
Multiple storage devices of the same type are configured to use the same account and password. The first time you configure a Storage Collector Agent to monitor one of these devices, create and assign a credential that contains the account and password. When configuring additional agents to monitor the rest of the devices, select and assign this existing credential to the devices.
•
A single storage device has multiple accounts that can be used to access it. When you configure a Storage Collector Agent to monitor this device, create and assign a credential for each account. When the Storage Collector Agent attempts to authenticate itself with the device, it tries the credentials one at a time until it connects successfully. Any remaining credentials are not tried.

This section contains procedures that describe how to create or select a credential. It also contains information about releasing Agent Manager lockboxes.

Creating and assigning new credentials

To create a new credential:
1
In the Credential Assignment Wizard, click New Credential - Create and Assign.
The available options differ slightly depending on the storage device.
2
In the Unique Name field, type a name that is unique to this credential.

If the Domain box is displayed, type the domain.
* 
IMPORTANT: If the Domain box is not displayed, and you need to specify the domain, include the domain as part of the account name.

Do one of the following:
•
If the Account Name and Password boxes are displayed, provide user credentials for the target application and/or the target server hosting the management application.
•
If the SNMP Community String box is displayed, type the SNMP community name assigned to the storage array group that you want to access.

In the Select the lockbox to contain this credential table, select a Foglight lockbox to contain this credential. For more information, see Creating a Lockbox for Foglight for Storage Management Credentials.
6
Click Submit.
The Credential Assignment Wizard page is updated to display the new credential.

For Hitachi Data Systems AMS, USP, and VSP devices, click Next to continue with Configuring the Hitachi Tuning Manager. For all other device types, click Finish to return to the Storage Device Setup dialog.

Selecting and assigning an existing credential

To select and assign existing credentials:
1
In the Credential Assignment Wizard, click Existing Credential - Select and Assign.
The Select Existing Credential dialog box opens.
2
Select the credential to use with the target storage device.
3
Click Submit.
The Credential Assignment Wizard page is updated to display the assigned credential.

For Hitachi Data Systems AMS, USP, and VSP devices, click Next to continue with Configuring the Hitachi Tuning Manager. For all other device types, click Finish to return to the Storage Device Setup dialog.

About releasing the Agent Manager lockbox

An Agent Manager lockbox needs to be released the first time an agent is deployed to the Agent Manager host. This releases the lockbox to the client Agent Manager Host, making all the credentials in the lockbox available to the agents on that host. You can release the lockbox from the Storage Device Setup wizard, the Edit Agent Properties dialog box, or from the Credentials dashboard.
