We reached limits on our Teradata VM environment and we would like to know if it is possible to increase disk capacity ? Where can we find a procedure for this ?
If your 'vm' is TD Express then no you can't.
If this is a 'TVME' system (i.e. licensed from Teradata) then you'll need to talk to your Teradata a/c team. I suspect that if it can be done theyll have to backup/reconfig/sysinit/restore to achieve this.
