After uploading packages to the filesystem (typically /var/lib/pulp/uploads/), you must synchronize the repository to import the uploaded content into Pulp’s database and make it available. The `hammer repository synchronize` command triggers this process. Creating a repository or content view is a prerequisite step done before the upload, not after.

Lifecycle environments in Satellite form a chain. To insert a new environment (QA) between Development and Production, you create QA with Development as its prior. You must then update the Production environment’s prior environment to be QA, otherwise Production would still point to Development, breaking the chain. The Library is the starting point, not an intermediate step.

The `hammer host info` command provides a comprehensive overview of the host’s configuration, including the ‘Content View’ and ‘Lifecycle Environment’ fields, which directly answer the question. While `hammer content-host info` is an older alias, `hammer host` is the modern subcommand. The other options either use incorrect subcommands or flags that don’t exist.

The ‘Subscriptions’ page in the Satellite web UI (Monitor -> Subscriptions) provides a detailed, filterable report showing consumption across all subscriptions. It allows you to drill down into a specific subscription and see a list of all content hosts consuming it. This is the primary, supported interface for subscription accountability. The `hammer` commands listed do not offer this specific, aggregated view.

In Satellite, host groups can have Puppet classes directly assigned to them under the Puppet Classes tab. This is the native, integrated method. When a host is created from this host group (or the host group is assigned to an existing host), Satellite’s built-in ENC automatically assigns those Puppet classes to the host. This ensures consistency and automatic application for future hosts.

When a content view version is deleted, the repositories on the content hosts still point to the now-missing Pulp repositories. Simply restoring the Satellite database will not automatically fix these broken client-side references. You must first unregister (`subscription-manager clean`) and then re-register the hosts. This forces them to get new repository URLs from the restored Satellite instance.

Within a content view, the order of repositories matters for dependency resolution. Yum will use the first repository in the list that provides a package. By placing the custom repository containing the specific library version above the standard RHEL repositories, you ensure that version is preferred, effectively overriding the base OS version for hosts consuming that content view.

Remote execution for a command like `yum update -y` uses a Job Template (the ‘Run Command – Script Default’ is a built-in template perfect for this). You target hosts using a search query (e.g., `os_major = 7`). To run it every 24 hours, you create a recurring schedule in Satellite with a cron-style definition (e.g., `0 2 * * *` for 2 AM daily). This is the direct method within Satellite’s remote execution framework.

Virtual data center subscriptions work on a per-physical-host basis. The `virt-who` service runs on the Satellite server or a proxy, and it contacts the hypervisor (vCenter, RHV, etc.) to get the list of guest IDs. If the hypervisor host itself is not subscribed to Satellite, or if `virt-who` is misconfigured, the association cannot be made, and guests will not consume from the virtual pool. The primary fix is to ensure the hypervisor hosts are registered and reporting correctly.
