Scheduled outage on June 17th, 2014

23 June 2014

Dear all,

During the outage scheduled on June 17th, 2014, maintenance operations have been performed on several systems. The tests of electrical installations and the intervention on the network did have some repercussions on the planned operations and delayed the restart of some services.

- Following the regulatory electrical tests a few machines lost their power supply which impacted temporarily dCache, Xrootd and iRODS.

- The intervention on the network has not been completed : the updates took more time than expected and we faced a software / hardware incompatibility. An other operation on the network is planned during an other scheduled outage. The network outage had minor impacts (NIS, nscd, AFS) that have been corrected by restarting the relevant services. But some maintenance operation on HPSS and TSM have been postponed.

- The restart of HPSS took longer than planned due to hardware incidents on the robotics. An on-site intervention by Oracle support helped cure the problem.

The next scheduled outage will take place near the end of September.
