JLab Scientific Computing Users,

The scientific computing environment will be unavailable during maintenance on Tuesday, December 15.

First on Tuesday morning, the farm computing environment will be stopped so that the scifs2 /work fileserver can be taken out of service, for troubleshooting recent ongoing fileserver issues. (Data currently on scifs2 is being relocated to other servers and will continue to be available after this server is removed).

Also, the interactive farm nodes ifarm1401 and ifarm1102 will be updated to QDR Infiniband, and ifarm1101 will be upgraded to CentOS 6.5.

In addition, the old Lustre 1.8 environment will be completely retired from service, and an old server sfsgw will be decommissioned.

Please plan for these necessary interruptions during the maintenance work on Tuesday.  Direct any questions or issues you have to [log in to unmask], 757-269-7152.

Sandy Philpott

IT Maintenance Day Set for Tuesday, Dec. 15, 5-10 p.m.
The IT Division is planning a maintenance period for 5-10 p.m. on Tuesday, Dec. 15. During this maintenance period, all MIS applications will be unavailable while patches are installed and the systems are rebooted. All MIS applications should be back up and available by 10 p.m. Also, all Common User Environment-managed web severs and login servers will be rebooted to finalize patch installations. A short incoming email outage will also occur while the email servers are updated. This email outage will be short and will last no more than 15 minutes. All incoming email will be queued on remote servers and delivered when service is restored. Finally, Windows and Linux patches will be released to all CUE desktops. Plan on rebooting your desktop to finalize patch installation no later than Dec. 18. If you have any questions or concerns, contact the IT Division Helpdesk at [log in to unmask] or x7155.
