Enabling Auto-Addressing
► To enable auto-addressing, set the “Auto Address Request” bit
(bit index 0, Drive Talk Drive-Control Flags).
Drive Control Flags
The “Drive Talk Drive Control Flags” let you get and send
configuration data, set up the Aries error log, and retrieve status
data.
NOTE: All Drive Talk control bits are self-clearing. To perform an
action one time, set the control bit. When the bit is cleared,
the action is complete or the action has timed out.
Configuration
You can get and send the configuration data of an Aries drive. On
power up the controller does not contain any drive configuration
data. When you get drive configuration data, the controller stores it
in the “Drive Talk Parameters”.
Upload
► To upload configuration data, set the “Get Configuration
Request” bit (bit index 1, “Drive Talk Drive-Control Flags”).
Download
► To download configuration data, set the “Send Configuration
Request” bit (bit index 2, “Drive Talk Drive-Control Flags”).
Error Log Flags
You can set the Aries drive to log errors you are concerned with.
Using the “Drive Talk Error-Log Flags”, set the bits for those errors you
want to monitor. Then use the “Send ERRORL Request” bit to send
the request to the Aries drive. The Aries drive logs the error data as
text.
Because the Aries error log is maintained as a text file, there is no
parameter or bit data the ACR controller can get. You can read the
error log by directly accessing the Aries drive. For more information,
see the section titled Using the “DTALK” Mode (below), and the Aries
User Guide, p/n 88-021610-01.
► To indicate what errors a drive is to log, set the bits in “Drive Talk
Error-Log Flags.”
► To send the error data request, set the “Send ERRORL Request”
bit (bit index 3, “Drive Talk Drive-Control Flags”).
