Pokerplayer, Kevin Kohler lied to you.
The Global Lock ONLY APPLIES to whatever DTC directly controls, but does not in any way restrict other entities from clearing and settling trades out of the DTC's direct control.
All stock trades are recorded by the DTC, global lock or not.
The below was from Kevin Kohler:
"The global lock simply means that DTC has suspended all trade settlement services for the particular security. With no legitimate means of settling trades, Scottrade will not accept orders for ANVH until the suspension has been lifted."
