Procedure Statement | A procedure for the steps involved to decommission a Service operated by a Resource Centre in the EGI infrastructure. |
Grid Service Decommissioning Procedure
This procedure drafts the good practices between a Resource Centre (aka site) and its users when a grid service is being decommissioned.
Definitions
- Resource Centre refers to the definition in the "Resource Centre OLA".
- In this document, the term "site" is deprecated, and Resource Centre has been used in its place.
- Other entities involved in this procedure are defined in the EGI Glossary.
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", “MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119.
Entities involved in the procedure
- Resource Centre Operations Manager: person who is responsible for initiating the decommissioning procedure by contacting the Resource Infrastructure Operations Manager.
- Resource Infrastructure Operations Manager (aka NGI manager) : person who is responsible for finding and agreement with the Resource Centre about the timeline, in order to minimize the impact on the user communities and infrastructure.
- Virtual Organizations (VO's): Data and other stateful objects of the supported VO's may be stored at the Resource Centre.
- Virtual Organizations (VO) managers: persons who are responsible for retrieving this data from the Resource Centre in due time. Tracking is done through their support unit in GGUS. If such support unit is not available, the VOs should be contacted directly using the contact information available in the VO ID card.
The Resource Infrastructure Operations Manager can determine the level of involvement of other actors together with the Resource Centre Operations Manager.
Contact information
- EGI Resource Infrastructure Providers are listed on the EGI web site
- A list of EGI Operations Centres with their respective contact information is available from the GOCDB
- EGI CSIRT: egi-csirt-team (at) mailman.egi.eu
- The list of VO's served by a specific Resource Centre and their ID cards can be retrieved from the Operations Portal.
- The VO managers and their contact information for a specific VO can be retrieved from the Operations Portal.
Actions and responsibilities
Resource Centre Operations Manager
- The Operations Centre is responsible for decommissioning the service.
- The Operations Centre is responsible for updating the corresponding entries in the EGI configuration repository GOCDB.
- The Resource Centre Operations Manager is REQUIRED to provide the necessary Resource Centre information needed to complete the decommission process, and he/she is responsible for its accuracy and maintenance.
Resource Infrastructure Operations Manager
- A Resource Infrastructure Provider is REQUIRED to be responsible for all Resource Centres within its respective jurisdiction. For this reason the Resource Infrastructure Provider is responsible for assuring that all the Resource Centres follow this procedure for services decommissioning.
VO's and VO managers
- give the users the relevant information about the decommissioning (deadlines, involved resources, files, how to handle it)
- follow-up and support users in their file migration procedures until the deadline
- inform Resource Centre about the status of the migration(s)
Workflow
Service Centre decommissioning
Steps
- Actions tagged RC are the responsibility of the Resource Centre Operations Manager.
