ISC_DRMI Node CONNECT ERROR
During locking tonight, had the following ERROR for ISC_DRMI:
EZCA CONNECTION ERROR: Could not connect to channel (timeout=2s): H1:LSC-PD_DOF_MTRX_SETTING_1_23
I tried a couple things: I hit "LOAD", which did nothing. Then I hit "Execute" which broke the lock.
One thing I did not do was Re-Request the state I was in. (Nutsinee just let me know that this is what works for her when she has had "CONNECTION ERRORS".
After double checking that all CDS systems are running, waiting a few minutes, and checking that you can do a caget with the channel in question, then change the operating mode of the node with the connection error from EXEC to STOP. Wait for node to change to a Yellow background before requesting EXEC again. If one of these nodes was previously managed, then you may need to INIT the manager (if the manager is working, a possible way to do this would be wait for the current state to finish, if it can, and then go to manual, INIT, and then back to where it was was).
