Importing and Managing Stemcells

Page last updated:

This topic explains how to use the Stemcell Library to import and stage stemcells to products.

The Stemcell Library shows a table with columns headed Product, Required, Deployed, and Staged as well as an Import Stemcell button and a Save Button

For more conceptual information about floating stemcells and stemcell upgrades, see Understanding Floating Stemcells.

WARNING: Some product releases require Xenial stemcells, as listed in Tiles Using Xenial Stemcells in PCF. If you are importing and using Xenial stemcells for the first time, see Updates for Xenial Stemcell Support.

Import and Stage a Stemcell

The Import Stemcell button is floated to the right of the Stemcell Library header next to the Save button

Download the appropriate .tgz stemcell file from Pivotal Network, then click Import Stemcell to permanently import a stemcell into Ops Manager.

A modal that appears after importing a stemcell. The modal reads, **Select the products you want to stage**. The modal has a checkbox next to the product name. It also has a dismiss button and an Apply Stemcell to Products button

To stage your stemcell to compatible products, enable the products in the Import Stemcell dialog. Click Apply Stemcell to Products to save your selections. Click Dismiss to dismiss the Import Stemcell dialog.

Choose a Stemcell Version

If you have uploaded multiple versions of a stemcell, you can use the dropdown in the Staged column to choose which version to use.

You can choose a different version until you deploy. After deployment, older stemcell versions are no longer available.

The dropdown menu for a stemcell is displayed in the Staged column. Three versions are available.

If the stemcell displays with a green checkmark and the words Latest stemcell below the Staged dropdown, the stemcell is the latest available version on your host. An outdated stemcell displays Stemcell out-of-date.

Beneath the **Staged** version dropdown, a green checkmark next to the words **Latest stemcell** appears. The stemcell in this image is the latest available version.
