Allocation Length

The library transfers either the number of bytes specified by the Allocation Length field or all of the available log sense data, whichever is less. The page lengths are:

  • 06h (6d) bytes for supported pages data
  • 28h (40d) bytes for the last n errors events page

Supported Pages Page

The Supported Pages Page lists all the Log Sense page codes supported by the library.

Last n Errors Events Page

The Last n Errors Event Page does not return specific error information. Instead, the operator should gather the log/error information from the GUI.
