The steps in this section restore the previous release of the product if restoration becomes necessary.
To display the NAMES file modification screen, enter the VMSERVER command. The format is:
VMSERVER name
Specifies the user ID of the CA VM:Director server. For more information about this ID, see Define the Product Deployment.
The first step in Deploying the Product for an Upgrade documented how to update the entry in the VMSERVER NAMES file to define a new Product Parameter File. You updated the PPF Name field on the screen by overtyping it. Reverse that step to restore the field to its original contents.
If you deployed this new product release to the ALTERNATE disk space, you can direct the product to revert to using the PRIMARY disk space the next time it is started. Deploying to ALTERNATE space leaves the older release intact on the PRIMARY disks. To bring back the old release of the product, set the Runtime Environment tag value to PRIMARY and restart the service virtual machine(s).
Note: For more information about the ENVIRONMENT tag, see the chapter "Defining a VMSERVER NAMES File Entry" in the CA Mainframe VM Product Manager Reference Guide.
If you deployed the new product release to the PRIMARY disk space, you can repopulate that space with the older release product materials. To copy product materials to the runtime disk space, enter the VMDEPLOY command using the following format.
VMDEPLOY name PRIMARY
Specifies the user ID of the product server machine being deployed.
Copies product files to the product PRIMARY disk space. This value results in overwriting the upgraded Product Materials from the newer product release or version with the older release materials.
After you resolve the situation that required you to back out the upgrade, repeat the upgrade procedure from the beginning to re-install the upgrade.
