Veritas Storage Foundation™ 5.0.1 for Oracle RAC Installation, Configuration, and Administrator's Guide Extracts for the HP Serviceguard Storage Management Suite on HP-UX 11i v3

NOTE: For SGeRAC database, when you issue the commands, replace $ORACLE_SID with
$ORACLE_SID=instance_name and provide the instance name on which the instance is
running.
In addition, you can also use the Oracle Enterprise Manager GUI to display storage mapping
information after file mapping has occurred. Oracle Enterprise Manager does not display I/O
statistics information.
Verifying Veritas Storage Mapping Setup
Before using the Veritas Storage Mapping option, verify that the features are set up correctly:
To verify that your system is using the Veritas Storage Mapping option
1. Verify that you have a license key for the storage mapping option.
# /opt/VRTS/bin/vxlictest -n "VERITAS Mapping Services" -f
"Found_Edi_map"
Found_Edi_map feature is licensed
2. Verify that the VRTSvxmsa depot is installed.
# swlist VRTSvxmsa

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 are recorded 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.
The command syntax is as follows:
/opt/VRTSdbed/bin/vxstorage_stats [-m] [-s] [-i interval -c count] -f
filename
Table 6-2 vxstorage_stats Syntax
You must log in as the database administrator (typically, the user ID oracle) or superuser.Prerequisites
• The -s specified option displays the file statistics for the specified file.
• The -c count option specifies the number of times to display statistics within the interval
specified by -i interval.
• 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.
• The -m option displays the I/O topology for the specified file.
• For more information, see the vxstorage_stats(1m) online manual page.
