SCSI Description
Quantum Atlas 10K II Ultra160/m SCSI Hard Disk Drives 5–53
5.13 LOG SENSE Command (4Dh)
NOTE
Log Sense data pages require special interpretation and also are
subject to change. For assistance with the Log Sense data pages,
contact your Quantum Applications Engineer.
The drive collects operational information and stores these statistics as log data. Log
data are grouped by category into log pages. The LOG SENSE command allows an
initiator to retrieve the stored log data. The LOG SENSE command is a
complementary command to the LOG SELECT command.
Each log page contains one or more pieces of information. Each piece of information
is referred to as a
parameter. There are two types of parameters: values and lists. In
general, error and performance counters are reported as values. For example, the
count of “Hardware Idled Due To Invalid Command” is returned as a 32-bit integer.
Events are reported as lists. For example, the last known failure might be reported
with the ASCII string “Last known failure code 960A(X)”.
