Warning: These advanced commands are potentially dangerous; use
         them only when directed to do so by NetApp
         personnel.
lab-netapp-01*> statit
statit: expected '-b'
usage: statit -b             take beginning snapshot of performance stats
       statit -e <flags>     take ending snapshot of stats and print report
optional flags include:
-n     append 'nfsstat -c' output to the report
-r     report counts over interval instead of per-second rates

Disk Statistics (per second) ut% is the percent of time the disk was busy. xfers is the number of data-transfer commands issued per second. xfers = ureads + writes + cpreads + greads + gwrites chain is the average number of 4K blocks per command. usecs is the average disk round-trip time per 4K block.
