The process of an NVR is normal and the NVR is in multi-machine mode, but the status of the NVR on the ESM is offline.
Emergency measures: Collect logs and restart the NVR.
Solution: Update the iNVS V100R002C01.
If the iNVS network and processes are normal, collect logs and restart the NVR to cope with the problem in an urgent situation.
Connect an SSH tool to the NVR.
The default user name is root
and default password is 123456
Under the root directory, run the getraidinfo command.
Collecting software RAID logs
After the command is run, raidinfo.tar
is generated under the root directory.
If the RAID program is abnormal, multiple NCQ errors can be found in the RAID logs.
