What should the engineer do to prevent Tier 1 storage from filling and causing poor performance?
use the “Copy to Tier” function to move data from Tier 1 to Tier 3
use the “Headroom” attribute for the Tier 1 disk folder to make more space
use the “Import to Lowest Tier” attribute for the volumes
use the “Re-route Migration Data” attribute for the Tier 1 disk folder
