The following shows an example in which the
view
operation is executed:
# /usr/DynamicLinkManager/bin/dlnkmgr view -drv
PathID HDevName OSPathID LDEV
000000 hdisk0 00000 9500V.0051.0005

4.2.6 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 shows how to execute the command:
# /usr/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:
# /usr/DynamicLinkManager/bin/dlnkmgr clear -pdst
