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.
Format
/opt/DynamicLinkManager/bin/dlmsetopt {-r retrycount | -inqt
InquiryTimeout | -inqr InquiryRetry | -prsup ReserveStatus| -h}
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 command executed from another application.
InquiryTimeout
Specify a numeric value of -1 or in the range from 1 to 3,600.
-1: This sets the timeout value to 30 seconds, which is HDLM's default
value.
