New Server for JASMIN Transfers?

Unified Model
,
1

Dear CMS Helpdesk,

I’ve read in the recent updates to JASMIN and their migration to the new Rocky 9 environment that they are not planning to replace gridftp1.jasmin.ac.uk. The server is still active at the moment but I guess at some point soon it will be closed down.

It says in the JASMIN documentation that the new hpxfer3.jasmin.ac.uk and hpxfer4.jasmin.ac.uk servers are active and equipped for ssh transfer from ARCHER2. However, when I tried recently to run a suite with transfer to JASMIN via hpxfer3, it failed to connect. Is this an issue that you are aware of?

The specific error is:

error: Unable to check destination url for sync: gsiftp://hpxfer3.jasmin.ac.uk/gws/nopw/j04/mh_gsp/Palaeoconditioning/u-dl162/18500101T0000Z/
globus_xio: Unable to connect to hpxfer3.jasmin.ac.uk:2811
globus_xio: System error in connect: No route to host
globus_xio: A system call failed: No route to host

I thought perhaps it’s to do with the cred.jasmin file? Is there a process for generating credentials specific to hpxfer3 or hpxfer4 servers?

Any advice is always appreciated, thanks!

Hi Alfred,

The hpxfer3 & hpxfer4 machines are equipped for use with ssh transfers only NOT gridftp. CMS will be announcing very soon the action that will be required & the changes that will need to be made to suites to continue transferring data from ARCHER2 to JASMIN. For the moment please continue to use gridftp1.jasmin.ac.uk until announced otherwise.

Regards,

Hi Alfred,

Just to follow up. See our new item IMPORTANT: Retirement of JASMIN Gridftp server for the announcement regarding retirement of gridftp1.jasmin.ac.uk and instructions on how to move to using Globus for data transfers.
