Subject:	Recent DaVinci Maintenance Periods

Greetings DaVinci Users, As many of you have noticed, we have had several scheduled maintenance periods on DaVinci since the beginning of the year. These have all been a result of our efforts to upgrade the operating system from SUSE LINUX Enterprise Server 9 (sles9) to sles10. Sles10 has been available for almost two years, and several projects have requested software which is only available under sles10. Unfortunately, we have encountered many serious problems with this upgrade. Some of these are due to the unique SGI ccNuma architecture, and some are due to NERSC's particular disk configuration. We are working closely with SGI to complete this upgrade. There are currently two more scheduled outages, on Wednesday March 12 and Wednesday March 19. Both of these outages will be from 07:00 - 17:00, Pacific Time. All scheduled outages are announced at least seven days in advance on the NERSC "Message of the Day" web page located at: http://www.nersc.gov/nusers/status/motd.php We appreciate your patience during this time. -- Best regards, David Turner User Services Group email: dpturner@lbl.gov NERSC Division phone: (510) 486-4027 Lawrence Berkeley Lab fax: (510) 486-4316
