NAME scsi_trace_decode - Decodes files produced by enabling the trace_scsi option SYNOPSIS /opt/SUNWsamfs/tools/scsi_trace_decode -f trace_file [eq_id] AVAILABILITY SUNWsamtp DESCRIPTION The scsi_trace_decode command decodes the raw SCSI trace file produced when the debug trace_scsi option in the defaults.conf file is enabled. OPTIONS This command accepts the following options: -f trace_file Specifies the trace file. Enter a full path name for the trace file. Typically, the trace file is /tmp/sam_scsi_trace_ml_eq_id, where ml_eq_id is the Equipment Number of the library that contains the devices being traced. For example, assume that you have two libraries. Their Equipment Numbers are 20 and 50. Each library has two tape drives, and their Equipment Numbers are 21, 22, 51, and 52. You could specify that trace information for devices 20, 21, and 22 go to file /tmp/sam_scsi_trace_20 and that trace information for devices 50, 51, and 52 go to file /tmp/sam_scsi_trace_50. eq_id Shows entries in trace_file for the device identified by Equipment Number eq_id only. The default is to show entries for all Equipment Numbers in this trace file.

Issue The scsi command has been issued. Reply The command completed. Completion status is shown. 09:22:45 The time of day when the command was sent or received. 8 The file descriptor upon which the command was issued. Not useful for non-Oracle Corporation analysts. cdb The cdb (command descriptor block): the scsi command issued. sense The sense data. If the command erred, then sense data is obtained and displayed. If the command did not err, then this field is all zero. Sense key ... Decoded sense data, showing the sense key, additional sense code, and additional sense code qualifier. These values define the error that occurred. Internal target failure The ASCII representation of the ASC, ASCQ information. SEE ALSO defaults.conf(4)
