12. The Service Action Allowed LED on the replaced drive drawer should be turned off automatically by
the controllers. If it is not turned off automatically, open the script window for the DCS3700 storage
subsystem, and execute the following SMcli script command:
set enclosure [enclosureID] drawer [drawerID] serviceAllowedIndicator=off;
Where:
v [enclosureID] is the identifier of the storage expansion enclosure that contains the replaced drive
drawer. Drive tray ID values are 0 to 99.
v [drawerID] is the identifier of the replaced drive drawer. Drawer ID values are 1 to 5.
This command turns off the blue Service Action Allowed LED that is located on the drive drawer
and allows the controller to access the storage expansion enclosure.
13. Use the DS Storage Manager to verify that the new drive drawer is operating correctly.
