5.3 Host Commands
(41) READ LOG EXT (X '2F')
The READ LOG EXTEND command reads versatile log data. Versatile log data includes the Extended SMART Comprehensive Error log, the Extended SMART
The number of the log to be read is specified as the Log address. For log data consisting of multiple sectors, a sector offset can be specified as an instruction so that data transfer starts from the specified sector. The number of sectors to be transferred is specified as the Sector count.
If an error occurs in the FP Queued protocol, Read Log Ext log page 10h containing the error information is transferred. This Read Log Ext log page can be read by specifying Sector offset = 00h, Sector count = 01h, and Log address = 10h. For the data format of Read Log Ext log page 10h, see Table 5.39.
The events of the PHY level on an interface are collected and it registers with Read Log Extend page 11h. This Read Log Ext log page can be read by specifying Sector offset = 00h, Sector count = 01h, and Log address = 11h. For the data format of Read Log Ext log page 11h, see Table 5.41.
If this command is not supported, or if an invalid value is specified for the Log address, Sector count, or Sector offset, the Aborted Command error occurs.
