Troubleshooting
Problem
Scheduled backups using the snapdiff option will fail with: ANS2831E Incremental by snapshot difference cannot be performed on '\\host02\api_test_vol$' as it is not a NAS NFS or CIFS volume
Cause
This is a limitation in the Tivoli Storage Manager Client software.
Environment
Windows
Diagnosing The Problem
Review the dsmsched.log for ANS2831E messages.
Resolving The Problem
To avoid this limitation, use the workaround stated below.
1. Define a schedule and associate it with the client. Verify the OPTIONS field is “-SNAPDIFF”
2. Make sure the scheduler service is configured to run under an account with admin privileges.
--------------- IMPORTANT -------------------------
3. Define a script to be run as a pre schedule command
net use \\hostname\vol$ <Administrator_password> /user:simulator\<Administrator_account>
4. In the dsm.opt file, make sure the volume is listed in the DOMAIN, for example:
DOMAIN \\hostname\vol$
5. Edit the options file for this node to call the pre schedule command file
presched <path\to\script.cmd>
Retry the scheduled backup that is now setup to call the script.
** If the problem is not resolved, try using the fully qualified domain name in place of the hostname.
