Use the vxstorage_stats -s command to display I/O statistics information. To see this information updated at regular intervals, also use the -i and -c options.
To display I/O statistics information
Use the vxstorage_stats command with the -s option:
$ /opt/VRTSdb2ed/bin/vxstorage_stats -s -f file_name
$ /opt/VRTSdb2ed/bin/vxstorage_stats -s -f \ /PRODqio/PRODqiotbs
Output similar to the following is displayed:

To display Storage Mapping and I/O statistics information at repeated intervals
Use the 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
$ /opt/VRTSdb2ed/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/VRTSdb2ed/bin/vxstorage_stats -s -i2 -c2 \ -f /prodqio/PRODqiotbs
Output similar to the following is displayed:
