The installvcs script handles most license key validations. However, if you install a VCS key outside of installvcs (using vxlicinst, for example), you can validate the key using the procedure described below.

1. The vxlicinst command handles some of the basic validations:

   node lock: Ensures that you are installing a node-locked key on the correct system

   demo hard end date: Ensures that you are not installing an expired demo key

2. Run the vxlicrep command to make sure a VCS key is installed on the system. The output of the command resembles:

   License Key      = XXXX-XXXX-XXXX-XXXX-XXXX-XXXX
   Product Name     = VERITAS Cluster Server
   Serial number    = XXXX
   License Type     = PERMANENT
   OEM ID           = XXXX
   Site License     = YES
   Editions Product = YES
   Features :
   Platform:        = Unused
   Version                   =  7.0
   Tier                      = Tiern3
   Reserved                  = 0
   Mode                      = VCS
   Global Cluster Option     = Enabled
   CPU_TIER                  = 0

3. Look for the following in the command output:

   Make sure the Product Name lists the name of your purchased component, for example, Cluster Server. If the command output does not return the product name, you do not have a VCS key installed.

   If the output shows the License Type for a VCS key as DEMO, ensure that the Demo End Date does not display a past date.

   Make sure the Mode attribute displays the correct value.

   If you have purchased a license key for the Global Cluster Option, make sure its status is Enabled.

4. Start VCS. If HAD rejects a license key, see the licensing error message at the end of the engine_A log file.
