Statistics for SCSI devices
LUN statistics can be divided into 3 categories:
• Generic statistics: They are commonly defined statistics independent of the class of the device.
They track activities such as number of times the device has been opened, open/close
failures, and so forth.
• I/O transfer statistics: They are commonly defined statistics independent of the class of the
device. They track activity related to I/O transfer: number of bytes read or written, total
number of I/O processed, etc. They are computed by consolidating I/O transfer statistics of
lunpaths of the LUN.
• Class driver specific statistics: They depend on the class of the device. They are maintained
by the class driver and require a plug-in module to be displayed.
