Hi,
We are encountering problems with the migration of the Oracle databases behind Castor back to their original disk arrays. There is a severe instability in one of the Oracle RACs that is being investigated.
We have extended the outage for Atlas and LHCb until lunchtime on Monday (1st February). For CMS and the 'GEN' instance the extension is to lunchtime Tuesday (2nd). The different timings are due to a reconfiguration that will enable part of Castor to be brought up earlier.
We are working to understand and fix the instability.
