When disk usage no longer exceeds the threshold, the alarm "Disk Threshold Exceeded" is not cleared
After you enabled File System monitoring (RFC 2790), when the File System usage is higher than the alarm threshold, you would receive a "Disk Threshold Exceeded" alarm below and the cause code is 0x40030.
After the File System usage usage no longer exceeds each alarm threshold which you have defined under "Monitored File System (RFC 2790)", the above alarm is still there and not cleared. The File System Condition also shows incorrectly which is "Minor Threshold exceeded".
