Regular maintenance of clusters requires downtime. By creating a maintenance schedule we can reduce surprises and not unnecessarily delay required maintenance.

Our maintenance operating steps

For a snapshot inventory, and the costs to CCB if they were hosted elsewhere, see ChemIT's spreadsheet in <R:\Chem IT\Projects & Tracking>. The data and analysis is in spreadsheet, "Chem IT Support & Services", tab "Alternative server costs".

Templates of notification emails

Two e-mails will be sent before the maintenance:

• One email will be sent to group users at two weeks before the maintenance down time. If there is any problem with the date and time, the group users should contact group IT representative. Then group IT representative should contact and discuss with us about the new date and time.
• The second email will be sent to all group users 24 hours before.

One email will be sent once maintenance is complete:

• one email will be sent to all group users about the completion of the work or extension of the downtime will be posted.
