Control Station: Check all callhome files delivered
Warning HC_CS_18800050328: There are 36 undelivered Call Home
incidents and 3 scheduled Call Home files left in the
/nas/log/ConnectHome directory(es)
Action :

Check the /nas/log/connectemc/ConnectEMC log to ensure the connection
is established correctly. To test your Callhome configuration, you can
run /nas/sbin/nas_connecthome -test { -email_1 | -email_2 | -ftp_1 |
-ftp_2 | -modem_1 | -modem_2 } command. View the RSC*.xml files under
the /nas/log/ConnectHome directory(es) and inspect the CDATA content
to find out and possibly resolve the problem. To remove the call home
incidents and files, run the command “/nas/sbin/nas_connecthome –
service clear”. Otherwise escalate this issue through your support
organization.

Control Station: Check auto transfer status
Warning HC_CS_18800050417: The automatic transfer feature is disabled.
