Symptoms

Unable to run a CAVA fsscan on file system in Unity.

Receive the following error:

svc_cava nasserver -fsscan -create
552913155: VC: 3: ERROR: File system not found.
Command failed
Error 13158645870: emcproduction02 : ERROR: File system not found.

Cause

The path provided was incorrect for the file system Mount path. Unlike VNX where it specifies only the file system name, the same does not work in Unity.

The following paths fail: 
/fs_name/ 
\fs_name
\fs_name\
\\nas_server\Filesystem\
//fs_name
and so forth

Ensure that CAVA is enabled and running before running the scan. The below command can check this: 
uemcli /net/nas/cava show
 
Example: 
uemcli -d 10.0.0.1 -u Local/joe -p MyPassword456! /net/nas/cava show
Storage system address: 10.0.0.1
Storage system port: 443
HTTPS connection
1: NAS server = nas_0
Enabled = yes
2: NAS server = nas_1
Enabled = no

Resolution

The syntax of the command is:  
svc_cava { <NAS_Server_Name> | ALL } [ -fsscan [<fs_mountpath> { -list | -create | -delete } ]
-fsscan [<fs_mountpath> { -list | -create | -delete } ]
Start, stop, or view the status of a full file system scan, where:
  • l <fs_mountpath> Specifies the location of the file system to be scanned. The Correct path is /fs_name
  • l -list Displays the scan status for the specified file system.
  • l -create Starts a full scan on the file system <fs_name>, and the offline options allow the file system scan on all offline files. By default, offline file systems are not included.
  • l -delete Stops the scan.
Example:  
16:43:50 service@APM001805XXXX spa:~/user> svc_cava nas_server02 -fsscan /test_fs -create
nas_server02 : commands processed: 1
command(s) succeeded
output is complete
8 dirs scanned and 22 files submitted to the scan engine firstFNN=0x0, lastFNN=0xe0f34b70, queueCount=0, burst=10

Additional Information

This option may be useful after an update of the virus definition files on the CAVA servers, to ensure that there is no existing infected file in the NAS server.

Another option to scan existing files is to enable scan-on-first-read feature. If no file system is specified when running the command, the -fsscan option displays the file system scan status for all file systems.
