4.3.6 Initializing Statistical Information for Paths

This section explains how to initialize statistical information (I/O counts and I/O

errors) for all the paths managed by HDLM.
This procedure is useful when you want to check the number of I/O operations and I/

O errors that have occurred since the last time the I/O counts and I/O errors were

initialized to

0

.

To initialize statistical information for paths:
1.

Check the current status of the path.
The following is an example of executing the command:


# /opt/DynamicLinkManager/bin/dlnkmgr view -path

2.

To initialize statistical information for all the paths managed by HDLM, execute

the

dlnkmgr

command's

clear

operation with the

-pdst

parameter specified.

The following is an example of executing the command:


# /opt/DynamicLinkManager/bin/dlnkmgr clear -pdst
