Hi,

  Is it possible to move a content database from one SQL drive to another without doing IISRESET because client does not want to

create an outage for other sites. 

the recommendation is to Dismount-SPContentDatabase, make the change and then mount-SPContentDatabase.

For this action you don`t need an IISreset
