Registering SLE Micro Clients

This section contains information about registering clients running these  SLE Micro operating systems:

  • SLE Micro 5.0 x86-64

  • SLE Micro 5.0 ARM64

Support for SLE Micro clients is provided as a technology preview for testing purposes, and not all features are fully functional at this stage. This feature is expected to be fully supported in a later version of SUSE Manager. Do not use this feature on production systems.

The SLE Micro is an ultra-reliable, lightweight operating system purpose built for edge computing. It leverages the enterprise hardened security and compliance components of SUSE Linux Enterprise and merges them with a modern, immutable, developer-friendly OS platform.

The SLE Micro uses transactional updates. Transactional updates are atomic (all updates are applied only if all updates succeed) and support rollbacks. They do not affect a running system as no changes are activated until after the system is rebooted. This information is displayed in the Systems  Details  Overview subtab.

1. Add Software Channels

Before you register SLE Micro clients to your SUSE Manager Server, you need to add the required software channels, and synchronize them.

The products you need for this procedure are:

Table 1. SLE Micro Products - WebUI
OS Version Product Name

SLE Micro 5.0 x86-64

SUSE Linux Enterprise Micro 5.0 aarch64

SLE Micro 5.0 ARM64

SUSE Linux Enterprise Micro 5.0 x86_64

Procedure: Adding Software Channels
  1. In the SUSE Manager Web UI, navigate to Admin  Setup Wizard  Products.

  2. Locate the appropriate products for your client operating system and architecture using the search bar, and check the appropriate product. This will automatically check all required channels. Click the arrow to see the complete list of related products, and ensure that any extra products you require are checked.

  3. Click Add Products and wait until the products have finished synchronizing.

Alternatively, you can add channels at the command prompt. The channels you need for this procedure are:

Table 2. SLE Micro Products - CLI
OS Version Base Channel Updates Channel

SLE Micro 5.0 x86-64

suse-microos-5.0-pool-x86_64

suse-microos-5.0-updates-x86_64

SLE Micro 5.0 ARM64

suse-microos-5.0-pool-aarch64

suse-microos-5.0-updates-aarch64

Procedure: Adding Software Channels at the Command Prompt
  1. At the command prompt on the SUSE Manager Server, as root, use the mgr-sync command to add the appropriate channels:

    mgr-sync add channel <channel_label_1>
    mgr-sync add channel <channel_label_2>
    mgr-sync add channel <channel_label_n>
  2. Synchronization starts automatically. If you want to synchronize the channels manually, use:

    mgr-sync sync --with-children <channel_name>
  3. Ensure the synchronization is complete before continuing.

2. Check Synchronization Status

Procedure: Checking Synchronization Progress
  1. In the SUSE Manager Web UI, navigate to Admin  Setup Wizard and select the Products tab. This dialog displays a completion bar for each product when they are being synchronized.

  2. Alternatively, you can navigate to Software  Manage  Channels, then click the channel associated to the repository. Navigate to the Repositories tab, then click Sync and check Sync Status.

Procedure: Checking Synchronization Progress from the Command Prompt
  1. At the command prompt on the SUSE Manager Server, as root, use the tail command to check the synchronization log file:

    tail -f /var/log/rhn/reposync/<channel-label>.log
  2. Each child channel generates its own log during the synchronization progress. You need to check all the base and child channel log files to be sure that the synchronization is complete.
