“Missing stemcell” shown for BOSH Director tile after upgrading Ops Manager to v2.10.46+

Products

• Operations Manager

Issue/Introduction

Previously it was only possible to deploy the Bosh Director with the stemcell that was bundled with Ops Manager. Later it's allowed to specify stemcell version for Bosh Director tile in Ops Manager. But there is a bug in Ops Manager versions prior to 2.10.46 that if the stemcell is upgraded first, then upgrading Ops Manager to a version that does not include that stemcell would fail. 

A fix is implemented in Ops Manager 2.10.46 that correctly flag the Bosh Director product as “Missing stemcell” to warn the operator that the Ops Manager doesn't have the binary on its local disk for the specified stemcell version. This is because when you export an Ops Manager installation settings for upgrade, the actual stemcell binary and the bosh release package won't be included.

Ops Manager 2.10.46 release note

* [Bug Fix] Upgrading stemcell, then upgrading Ops Manager to version that does not include that stemcell does not fail

When the "Missing stemcell" flag is shown, "Apply Changes" for Bosh Director tile should fail because it can’t find required stemcell binary on disk. 

 

Environment

Product Version: 2.10

Resolution

To resolve this issue, you can either upload required version of stemcell to Ops Manager and use the that one

Or specify older version of stemcell (e.g. the one shipped with Ops Manager) for Bosh Director tile


To avoid such situation for Platform Automation, add one more step to upload the required version of stemcell after importing Ops Manager installation settings.
