To display storage mapping and I/O statistics information at repeated intervals
vxstorage_stats command with the -i interval and -c count options to display storage mapping and I/O statistics information at repeated intervals. The -i interval option specifies the interval frequency for displaying updated I/O statistics and the -c count option specifies the number of times to display statistics.
$ /opt/VRTSdbed/bin/vxstorage_stats [-m] [-s] \[-i interval -c count ] -f file_name
For example, to display statistics twice with a time interval of two seconds:
$ /opt/VRTSdbed/bin/vxstorage_stats -s -i2 -c2 \-f /data/system01.dbf
Output similar to the following is displayed:
