DNAC Assurance Backup

[CSCO11733021]

Hello All,

I want to take backup of DNAC assurance. When I have configure NFS settings on DNAC it gave me below error..

Remote directory issue: Error running showmount on remote server: '['showmount', '--no-headers', '--exports', '10.46.0.148']'. Output: 'clnt_create: RPC: Port mapper failure - Unable to receive: errno 0 (Success)

Would you encountered this error ?

I could able to take backup but without assurance options.

is there anything to be enabled on DNAC box ?

From the other post:
Server Requirements for Assurance Backup
To support Assurance data backups, the server must meet the following requirements:
Support NFS v4 and NFS v3 (To verify this support, from the server, enter nfsstat -s)
Have read and write permissions on the NFS export directory
Have a stable network connection between Cisco DNA Center and the NFS server
Have sufficient network speed between Cisco DNA Center and the NFS server

See here for greater detail: https://www.cisco.com/c/en/us/td/docs/cloud-systems-management/network-automation-and-management/dna-center/1-3-3-0/admin-guide/b_cisco_dna_center_admin_guide_1_3_3_0/b_cisco_dna_center_admin_guide_1_3_2_0_chapter_0110.html

I suggest working with TAC as well if it is still failing after ensuring you have met the requirements. Good luck & HTH!
