7.6 dlmsetopt Utility for Setting HDLM Driver Options
This utility changes the settings for the HDLM filter driver. Restart the host machine
to apply the changed settings. Note that you do not need to restart the host machine
every time you execute the
dlmsetopt
utility. If you execute the
dlmsetopt
utility
more than once, restart the host after you have finished specifying all settings.
Restarting the host enables all the changed settings.

7.6.2 Parameters
-r
Specify the number of retries when memory is allocated in the filter driver. This
memory is allocated for processing I/O requests from users. If memory allocation
fails, the system retries at intervals of 0.05 seconds. If retrying for a long time
results in I/O not being executed, set an appropriate retry count. If that retry count
is exceeded and memory allocation fails, the KAPL05708-E message is output to
syslog and to the HDLM manager log file.
retrycount
Specify a numeric value from -1 to 2,147,483,646.
-1 : The system retries until memory is allocated. This is the initial value of
the system.
0 : The system does not retry.
1 to 2,147,483,646: The system retries the specified number of times.
If the following values are specified, the message KAPL12559-E is
displayed and then the processing terminates:
• Non-numeric value
• Value less than -1
• Value more than 2,147,483,646
-inqt
Specify, in seconds, the timeout value of the
SCSI INQUIRY
command. In
HDLM, the default timeout value is 30 seconds. Note that the timeout value
specified by using the
-inqt
parameter only applies to the
SCSI INQUIRY
command executed from HDLM. This value has no effect on the
SCSI INQUIRY
