Initializing statistical information for paths

To initialize 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.

1. Check the current status of the path.

   The following shows how to execute 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 shows an example in which the command is executed:

   # /opt/DynamicLinkManager/bin/dlnkmgr clear -pdst
   KAPL01049-I Would you like to execute the operation? Operation name = clear [y/n]:y
   KAPL01001-I The HDLM command completed normally. Operation name = clear, completion time = yyyy/mm/dd hh:mm:ss
   #

3. Check to see whether the statistical information for all the paths has been initialized.

   The following shows how to execute the command:

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