Archer to JASMIN transfers

Unified Model
1

Hello CMS

I am working with a Nesting suite where I have added additional workflow steps to transfer out files onto JASMIN gws after the jobs are over (suite u-dg192). It works fine but is a bit glitchy. When it connects via the host name aurocumulus@ln02, it transfers seamlessly which is desired. But often is the case, that it attempts to login through @ln01/ln03/ln04 when the transfer fails (archive_files_Alps and archive_files_Him steps). Is there a way that for transfers, I can mention somewhere that archer makes a connection with JASMIN only through ln02?

Hi Sid,

You have 2 options:

Either 1) add

[[[remote]]]
   host = ln02

To the task definition for archive_files_Alps and archive_files_Himalayas in the suite.rc file to force it always use ln02.

or 2) Set-up your ssh-agent on all the login nodes so it doesn’t matter which one is picked.

Regards,
Ros
