How to put your SE in maintenance status

Although there actually is a way to publish an "inactive" status for a storage element in the information system, most clients do not (yet) look at the GlueSEStatus attribute to determine if the SE can be used: they will just try and fail (possibly after a timeout) when the SE happens to be unavailable. The user application might then try using another SE instead.

To help clients avoid trying an SE that is unavailable, the site admin could temporarily remove it from the site BDII, e.g. by switching off the resource BDII of the SE.

In any case, when an SE (or any other grid resource) is unavailable, a proper downtime record should be registered in the GOCDB. Some VOs (e.g. LHC experiments) will extract such records to blacklist resources according to the published downtime periods.
