Hi @Vaibhav Waghmare , 

I checked he details. 

From the error, we see the Chunk processing is failed. I suggest to check the following options:

1. On the Particular disk and mount path, check if you are available to acces the chunk on its folder eV_xxxxxxx]. 
2. Check if the Read/write permissions are given to the folder/path
3. Check if the chunk is in readable format and having all files on it. 
4. As the error message mentioned the job ID, go to that Client/Job and run a verification job to check if the particular job is healthy or not. 
5. If the Verification job fails, there are chances that the job is corrupted due to bad chunk/file. 

Further if the issue persists, please reach out to Commvault team for a detailed review on the issue. 

Also, please refer the available solutions on Commvault Docs with similar issues:
