Setting the VASA credentials

The VASA credentials comprise a username and a password that is set separately from the Spectrum Connect user accounts, and separately from the storage system credentials.

VMware vCenter servers can use the VASA credentials to connect to Spectrum Connect and utilize VASA functions, as explained in Registering Spectrum Connect as a storage provider on vCenter server.

From the Spectrum Connect UI you can set, change, or display these VASA credentials at any time.

Note:

Only one set of a username and a password can be used for the VASA credentials, which applies to all vCenter servers that require VASA functions and connect to Spectrum Connect.
The same operations are available from the CLI as well, as explained in CLI – Setting the VASA credentials.

Click VASA Provider settings on the Settings menu.
The VASA Provider settings dialog box is displayed.

Enter the username and password that you want to set, confirm the password and then click Apply.

Note: The VASA username must be different from any username stored in the Spectrum Connect user database. See Managing Spectrum Connect users.

In the Priority drop-down box, select a priority (0–255) of Spectrum Connect as a storage provider in vCenter. In its turn, it defines priority of all storage systems added to the current Spectrum Connect instance on the vCenter server.

Note: You can use the Priority setting for resolving an issue, when a Spectrum Connect instance defined for the same storage system is active on one vCenter server and passive on another vCenter. This might occur, when two SC instances with the same priority, managing the same storage system are registered as storage providers on two different vCenters. A loss of connectivity between any of the Spectrum Connect instances and vCenter servers might result in the following configuration:

Spectrum Connect A is an active storage provider on vCenter 1.
Spectrum Connect B is an active storage provider on vCenter 2.

This renders Spectrum Connect A to be the active storage provider on vCenter 1 and passive on vCenter 2. In its turn, Spectrum Connect B is active provider on vCenter 2 and passive on vCenter 1. To avoid this situation, use the Priority parameter to define the required Spectrum Connect instance to have a higher priority than another one. This ensures that it remains active after a failover.
