Description: 

Dear int11r, int12r, int2r, int8r and test2 integration database users,

Due to a risk of database storage corruption possible, in current storage systems used in IT-DB, we are starting a campaign of patching the storage systems. In order to safely patch the storage systems, we need to briefly suspend the activities on many databases at once and we are starting this with the integration databases mentioned above (for the full list of services affected please look below). The intervention will NOT be transparent and will require 30 minutes of suspension of database activity. We would like to conduct the intervention on

         Thursday, 13th of June 2013 between 9:30 and 10:30

Services affected will be:
INT11R_LB, INT11R_NOLB, LCG_CERT_SAM_INT11R, LCG_DASHBOARD_INT11R, LCG_DPM_INT11R, LCG_FTS_INT11R, LCG_FTS_PPS_INT11R, LCG_GRIDOPS_INT11R, LCG_GRIDVIEW_INT11R, LCG_LDIF_INT11R, LCG_LFC_INT11R, LCG_MESSAGING_INT11R, LCG_SAM_INT11R, LCG_SITEMON_INT11R, LCG_VOMS_INT11R, INT12R_LB, INT12R_NOLB, CMS_POPULARITY_SYSTEM_INT2R, CMS_VAL_LB, INT2R_APEX, INT2R_LB, INT2R_NOLB, INT8R_LB, INT8R_NOLB, INT8R_PANDA, TEST2_APEX, TEST2_LB, TEST2_NOLB, TEST2_NIGHTLY

Please note that during the intervention the database will be suspended for around 30 minutes (no sessions will be lost, but no queries or data modifications will be possible during that time)!
