Abstract
As I reported in klog#32854 camera servers couldn't be updated due to the expired OS though they have several problems.So I launched a test server with new environment and it works fine.
A next step is to move it to the mine and connect some camera which is not used so frequently such as BS, IFI, etc.
Details
Update test was done by Ikeda-san in a few years ago (see also klog#22965) and construction procedure was also prepared as JGW-T2214512. After this work, the camera packages were updated in LIGO and compatible OS list was also updated. So I re-tried to construct the camera server on modern OS. Install procedure will be uploaded JGWDoc soon.A format of configuration file for camera server is changed from old one. So I updated a client script (/kagra/apps/camera-bin/camera_client.py) and the client script can parse both old and new format. Because operation commands were also different, a recovery script (/kagra/apps/camera/bin/camera-service-client.sh) was also updated. So end user can recover from GigE troubles same manner as before (see also Recovery manual). After these updates, we can now mix the old and new camera-server code without any conflict of commissioning activities. (A new camera server is actually running as k1cam2 in DGS network with a spare GigE camera and client applications can access both old camera-server on k1cam[01] and new camera-server on k1cam2.
Next work is to move k1cam2 in the mine and to connect some cameras which are not so important such as BS, IFI, etc. Finally all cameras will be moved to the new camera-server gradually and k1cam0 and k1cam1 will be also upgraded to the new environment.
