Overview
The Service type decommission procedure was created to define steps which have to be taken to remove service type from prodcution infrastructure.
Terminology
Support deadline
- from this day service type is unsupported
- sites should not register retired services in production infrastructure
- NGIs and sites should start action to move their services to supported versions
Decommission deadline
- from this day no services for the retired service type can be present in production infrastructure
- in case of violation security team can remove the site from production infrastructure
- service type is removed from operations tools
Steps
Following steps are taken since support deadline is known for COO
- COO on OMB announce decommission deadline for service migration
- The broadcast is send to NGI managers and Site administrators
- NGI managers announce the information to the sites
- Documentation about decommissioned service should re-classified as obsoleted (I would not remove it from our wiki, but I would just reclassify it)
- New probe is developed for the MW nagios that extracts hostnames from GOCDB and BDII associated to type and raises critical alarm in the operations dashboard
- ROD teams followup the service migration till the decommission deadline - site admins should provide migration or decommission plan. See escalation procedure
After Decommision deadline
- Probes for the service are removed from profiles:
- ROC
- ROC_OPERATORS
- ROC_CRITICAL
- the SAM probes at the earliest convenience are removed from the SAM release
- CSIRT team followup the migration and if needed suspend sites which didn't migrate
- If a service specific SU in GGUS exists, the SU should be removed from GGUS
- The service type should be disabled in GOCDB (i.e. service entries can no more declared to be of the service type), but existing instances associated to the type continue to exist
