- This Thursday, 12.03.2020, a new DESY guest WLAN will be brought into
operation: Science-Hotspot. This replaces DESY-Guest and XFEL-Guest.
The new WLAN does not require a registration, one click to accept the
terms and condition will be sufficient.
The action will take place early Thursday afternoon. Connections
will be broken at that time. As soon as Science-Hotspot becomes
visible it can be used.
- GPFS outage 5.3.2020: at 1:54 a GPFS deadlock occured on one of the ESS
building blocks, maybe due to a faulty RDMA send. The issue was
brought to IBM they investigate.
- SardanaAIO.py, ignore offline motors: motors that are offline are ignored; offline: state cannot be
evaluated or state is FAULT or state is ALARM.
The change is a measure against crashes caused by terminating Macros by Ctrl-C.
SardanaAIO still inserts other devices that are offline into the Pool. To
make them available: start the device servers and issue 'SardanaRestartBoth.py -x'.
- SardanaAIO no longer creates core dump files. '-c' command line option still exists but is ignored.
- Taurus slow, P65: the problem depends on the application, under investigation.
Possible workaround: TngGui.py. To prevent users from accessing certain motors,
it is possible to select motors on the command line:
$ TngGui.py eh_mot01 eh_mot02
selects 2 motors
$ TngGui.py eh_mot0
selects 9 motors
The pattern is not used for other devices.
- Nexus entities: the directories /online_dir/nexusSaves/dir_00001, etc.
contain the lists of components, mandatory components, data sources and profiles (.lis).
In addition they contain the xml files describing the components and data sources and
the json files for the profiles.
An exercise to save-delete-restore Nexus components and data sources
can be found
