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.
1
.
Check the current status of the path.
The following is an example of executing the command:
dlnkmgr -s host-name -u user-name -p password 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:
PROMPT>dlnkmgr -s host-name -u user-name -p password 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
PROMPT>

.
Check to see whether the statistical information for all the paths has been
initialized.
The following is an example of executing the command:
dlnkmgr -s host-name -u user-name -p password view -path
Viewing and Setting Up the Operating Environment
This section explains how to display and set up the HDLM operating
environment.
Viewing the Operating Environment
To display the operating environment, execute the dlnkmgr command's view
operation with the -sys and -sfunc parameters specified.
The following is an example of executing the command:
PROMPT>dlnkmgr -s host-name -u user-name -p password view -sys -sfunc
