NetApp NFS error and troubleshooting tools

1) Mount:  Verifies the exports that are mounted on the client
2) Showmount -a <storagesystem>: Lists all mounts from a storage system
3) Showmount -e <storagesystem> List all mounts available from a storage system
4) rpcinfo -p : Helps confirm is NFS service is listed (port 2049)

Review Secd Logs
::> set diag
::*> debug log files modify -incl-files secd
::*> debug log show or ::*> debug secd log show -node <NodeName>
The secd log are located at /mroot/etc/log/mlog/secd.log

you can also use diag secd authenticate translate command to verify the name mapping
similarly, diag secd authenticate show-creds is a useful command


A way to check if client has access to an export is to use the following command:
export-policy check-access -vserver

Within autosupport look for export-rule-table, nfs-servers-by-volume etc.
