Purpose
Enables tape acceleration (and write acceleration—if
not already enabled).
Enables tape acceleration with automatic flow
control (default).
Sets tape acceleration flow control buffer size to 2
MB.
Disables tape acceleration (default) and resets the
FCIP tunnel.
The write acceleration feature remains
Note
enabled.
Changes the flow control buffer size to the default
value of automatic. The tape acceleration and write
acceleration features remain enabled. This command
does not reset the FCIP tunnel.
Disables both the write acceleration and tape
acceleration features and resets the FCIP tunnel.
