Using vxstorage_stats

The vxstorage_stats command displays detailed storage mapping information and

I/O statistics about one or more VxFS files. The mapping information and I/O statistics

exist only for VxFS files and VxVM volumes.

In vxstorage_stats command output, I/O topology information appears first

followed by summary statistics for each object.

Some highlights on this command:

◆ You must log in as the database administrator (typically, the user ID oracle).

◆ The -m option displays the I/O topology for the specified file.

◆ The -s option displays the file statistics for the specified file.

◆ The -c

count

option specifies the number of times to display statistics.

◆ The -i

interval

option specifies the interval frequency for displaying updated I/O

statistics.

◆ The -f

filename

option specifies the file to display I/O mapping and statistics for.

◆ Refer the vxstorage_stats(1m) online manual page for more information.

Displaying Storage Mapping Information

Use the vxstorage_stats command with the -m option to display storage mapping

information:

$ /opt/VRTSormap/bin/vxstorage_stats -m -f

file_name

For example:

$ /opt/VRTSormap/bin/vxstorage_stats -m -f /oradata/system01.dbf

Note For file type (fi), the SIZE column is number of bytes; for volume (v), plex (pl),

sub-disk (sd), and physical disk (da), the SIZE column is in 512-byte blocks. Stripe

sizes are given in sectors.

Displaying I/O Statistics Information

To display I/O statistics information, use the vxstorage_stats command with the -s

option:

$ /opt/VRTSormap/bin/vxstorage_stats -s -f

file_name
