A Teradata crashdump table cannot be automatically saved if:
- The ctl Save Dumps setting is off.
- An AMP is down and FALLBACK is not defined for Crashdumps database. This will not happen on platforms optimized for fallback because fallback is defined automatically.
- The system is not up.
- There is not enough space.
You can, however, manually save crashdumps using the CSP utility. For more information, see Manually Saving Teradata Crashdumps to the Crashdumps Database.
