There will be a scheduled maintenance on Hexagon on November 6th from
10:00. We expect the maintenace will take around 8-10 hours. There
will be no access to the machine. All running jobs will be affected,
therefore a reservation is set in the system to prevent from starting
jobs which can't finish before the maintenance.

During the maintenance we are going to update:

* software on hexagon management station
* software on compute nodes to version CLE4.2UP01

Update: 18:20 update finished, machine is open for access.
