You display this information by executing the HDLM command's view operation with
the
-drv parameter specified. For details on the view operation, see 6.7 view
(Displays Information). The execution result of this operation is displayed on a single
line for each path.
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
000001 hdisk1 00000 9500V.0051.0015
000002 hdisk2 00000 9500V.0051.0020

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
