Expanding EBS Storage
PrerequisiteRead the requirements and limitations before proceeding. See Storage Expansion.
This procedure should be used only after launching a Teradata Database instance.
If the storage expansion fails while you are running the utility, the system may have volumes that are greater in size than others. Re-run the utility with the same parameters. The process will continue where it left off.
- Stop the database.
# tpareset -y -x Shut down database to expand storagePutting the database in this state takes a few minutes.
- Wait for the database to shut down.
# psh pdestate -wPDE state: DOWN/HARDSTOP
- Run the utility.
# tdc-expand-storage --size value -ywhere:
After the utility runs, Volume Change Successful! displays in the output.
- value is the amount, in TB, you want to increase on each node. For example, if the current system has 5 TB per node, entering 5 increases the system to 10 TB per node.
- -y is an optional command that bypasses the confirmation prompt. Use this command only if you know the configuration of the system.
- [Optional] From inside the instance, view /var/log/tdc-expand-storage.log for the status or troubleshooting issues.
