When I set a CI to maintenance mode manually in SOI it switches to maintenance mode in UIM as expected. But after 2 minutes it changes back into production mode in UIM.
SOI 3.3 and SOI 4.0
UIM connector 3.0.71
The problem is seen because the default maintenanceModeScheduleDuration in the \CA\Catalyst\CatalystConnector\registry\topology\physical\<hostname>_CatalystConnector\modules\configuration\NimsoftConnector.xml
File is 120000 which are 2 minutes.
You can modify the value for maintenanceModeScheduleDuration to your prefered time. If you leave the value empty
The duration will be 2 months.
