Alarm Information
Handling Process
Step 1  Check whether the hardware is normal. If no, find out causes.
Step 2  If the hardware is normal, run the ssh_connect command under debug and type the password 123456 twice. This operation is carried out on one controller.
Step 3  If the problem persists, run the following command on the two controllers:
rm -rf /tmp/.ssh/*
rm /root/.ssh/*
Do not delete files wrongly.
Run the ssh_connect command on one controller.
Step 4  If the problem persists, check the /root/ directory permission. Run the chmod 755 /root/ command to change the permission
Root Cause
The communication between two controllers of the VIS is abnormal and the command cannot be transferred correctly.
