About SMT

To help with product updates and registrations centrally via a local server without requiring each server to have outgoing connectivity directly to Suse Customer Center (SCC) or Internet. This also helps in avoiding repeat download of OS update packages for each server over WAN link.

Error while registering an internal machine with local SMT

We might see error such as below while using local SMT server:

Activating SLES_SAP 15.1 x86_64 ...
Error: Registration server returned 'Product not (fully) mirrored on this server.
Mirroring of the following repos has to be enabled on the SMT server:
  * SLE-Product-SLES_SAP15-SP1-Pool (SLES_SAP,15.1,x86_64)
  * SLE-Product-SLES_SAP15-SP1-Updates (SLES_SAP,15.1,x86_64)

For these refer:

• https://documentation.suse.com/sles/12-SP4/html/SLES-all/smt-mirroring.html
• https://documentation.suse.com/sles/12-SP4/html/SLES-all/smt-installation.html

Basics of SMT

We can use

To list all repos

smt-repos

List only repos that are mirrored

smt-repos -m

See whether specific repository is mirrored

smt-repos | grep SLE-Product-SLES_SAP15-SP1-Pool

Enable mirroring for a repository

• smt-repos -m -e SLE-Product-SLES_SAP15-SP1-Pool
• smt-repos -m -e SLE-Product-SLES_SAP15-SP1-Updates

Then sync via

smt-sync; smt-mirror

Troubleshooting SMT issues

Unfortunately when we enable verbose and logging for smt-sync it is clear that sites are not reachable

 smt-sync -v 5 --logfile /tmp/smt.log 

followed by 'tail -f /tmp/smt.log' we can see:

Enabling repositories at SMT server for sync / mirror

We can see which repositories are enabled via:

# smt-repos | grep SLE-Product-SLES_SAP15-SP1-Pool
| No      | 2910 | nu   | SLE-Product-SLES_SAP15-SP1-Pool                                     | sle-15-ppc64le | SLE-Product-SLES_SAP15-SP1le                                    | No              | No      |
| No      | 2911 | nu   | SLE-Product-SLES_SAP15-SP1-Pool                                     | sle-15-x86_64  | SLE-Product-SLES_SAP15-SP14                                     | Yes             | No      |

We can optionally enable a repo using:

# smt-repos -m -e SLE-Product-SLES_SAP15-SP1-Pool
1 repository enabled.

Then validate whether repository is enabled properly or not via:

# smt-repos | grep SLE-Product-SLES_SAP15-SP1-Pool
| No      | 2910 | nu   | SLE-Product-SLES_SAP15-SP1-Pool                                     | sle-15-ppc64le | SLE-Product-SLES_SAP15-SP1le                                    | No              | No      |
| Yes     | 2911 | nu   | SLE-Product-SLES_SAP15-SP1-Pool                                     | sle-15-x86_64  | SLE-Product-SLES_SAP15-SP14                                     | Yes             | No      |
