The Corral login node login1.corral.tacc.utexas.edu will be retired during this maintenance. Users accessing Corral through the SSH/SCP hostname login1.corral.tacc.utexas.edu should update their configurations to use data.tacc.utexas.edu as the target host for SSH sessions and SCP transfers.

New Corral Login Node

The Corral login node, accessed as corral.tacc.utexas.edu or login1.corral.tacc.utexas.edu, will soon be retired and replaced with general-purpose “data transfer nodes”, all accessed through the alias data.tacc.utexas.edu. Alongside this transition, the new nodes will require the use of TACC’s multi-factor authentication tokens ( https://portal.tacc.utexas.edu/tutorials/multifactor-authentication).

This transition will allow us to better serve our user community with improved performance, reliability, scaling and security.

The new data transfer nodes are available now for testing, and provide direct access to both the Corral 3 file systems as well as the Stockyard/work file system. These nodes have all the most common file transfer facilities installed, including the iRODS client “i-Commands" and the Globus GridFTP client tools.

If you have automated transfers or otherwise perform large-scale data transfer through the current Corral login node you should test your workflows using the new data transfer nodes as soon as possible.

Note that no data migration from the /home areas of the Corral login node will be performed since those areas are not intended for any significant data storage. If you have configuration or other files stored in $HOME on corral.tacc.utexas.edu then please migrate these files to the data transfer node or another resource in a timely manner to ensure you do not lose any data.

A follow-up notification will be sent in the coming weeks announcing the retirement date for the current Corral login node. Please ensure that you have tested any workflows relying on the current Corral login node with the new infrastructure prior to the final shutdown date.

Please submit any questions you may have via the TACC User Portal.
