Error: Bad file descriptor There are network connectivity issues between the source and the target primary server. Please refer troubleshooting section in user guide for more details.

Cause

1. sourcesecret.tar file is corrupted
2. sourcesecret.tar has expired.

Solution

1. Add the default port 9990/9991/9992/9993/9994/9995/9996/9997/9998/9999 into the firewall exception list.
2. Check if the sourcesecret.tar file is present at the source primary server.
   a) If not, then copy it from the target primary server.
   b) if yes, then:
   1) delete the following from nbsm directory:
       Source primary server:
       I) sourcessl
       ii) sourcesecret.tar
       Target primary server:
       I) targetssl
       ii) sourcesecret.tar
   2) Generate the sourcesecret.tar on target primary server using the following command:
       "nbsm_target -generate_sourcesecret <number_of_days>".
       Example: nbsm_target -generate_sourcesecret 2
   3) Copy the newly generated sourcesecret.tar from target primary server to source primary server in nbsm folder.
   4) Proceed with the report/overwrite operation.
