Print this reportTest of a new guardian serverA new guardian server was prepared as k1grd1 on the Debian13 system and now only SYS_SDF is running on this new server as an initial test. Detailed installation procedure can be found in JGW-T2617316.
Because the guardctrl, guardlog, and guardutils commands determine which Guardian server to connect to based on the GUARD_HOST, GUARDCTRL_HOST and GUARDLOG_HOST environment variables, we cannot currently view logs of SYS_SDF from the MEDM screen. Additionally, we cannot use guardctrl to perform start/stop/restart operations (not EXEC/PAUSE/STOP via MEDM screens) without changing these environment variables to "k1grd1". Since I don’t think we would perform the above operations including viewing logs on SYS_SDF when it is not under observing runs, it shouldn't be a problem. But, please be careful if such a situation arises.
Any other guardian nodes are still running on k1grd0 which is a current production server and haven't been tested yet. So the others can be operated as usual.

Print this reportLoading check of guardian nodes were done. Complete user code check hasn't been done because it requires to enter each GuardState one-by-one. The GStreamer environment must be set up for a mode analysis by OMC_LSC guardian. All guardian nodes should work fine with minor (but might be many) user code fixing after setting up the GStreamer environment.
Special Notes
python3-foton package was installed for loading kagralib.py. Because the automatic filter generation function by Guardian that Nakano-kun used is likely no longer in use, python3-foton may no longer be necessary.
Log-in configuration from the new guardian server to k1dc0 and TCam servers was set for SYS_DAQ and TCam guardians. Now DAQ kill and Taking TCam photos work fine on the new guardian server.
Thanks to the net-masquerade for PICO network by k1script, HWP in LSC_LOCK guardian can be used without any modification.
Mode analysis binary can be used also on the new server without any linker mismatch.
Taking GigE picture for mode analysis of OMC_TRANS haven't work yet due to missed some plugins of GStreamer. Set up of them on the new guardian server will be required.
