Disclaimer, I recommend you call 3PAR support and get their assistance in fixing this, and also perform their recommended actions during a time when its safe to take an outage.
If you choose to disregard that advice, deleting only LUN 8's template should result in ONLY LUN 8 being removed.
Of concern is that is what might happen if your system(s) try to use LUN8... are they smart enough to recognize the drive has a signature already mounted elsewhere? Is there a SCSI2/3 lock on LUN0 that is keeping LUN8 safe? Or is the system dumb enough to try/allow LUN 8 to be formated as a new datastore?
On a different note, what sort of backup do you have set up there? Looks like you have an VTL appliance mapped directly to the live LUNs.
