You can use a template file to upload a series of changes to the DMP configuration to the same host or to another similar host.
Veritas recommends that you load the DMP template to a host that is similar to the host that was the source of the tunable values.
To configure DMP on a host with a template
# vxdmpadm config dump file=filename
The target host may include non-shared arrays or host-specific arrays. To avoid updating these with settings from the array name or array type, define an enclosure section for each of those arrays in the template. When you load the template file to the target host, the enclosure section determines the settings. Otherwise, DMP applies the settings from the respective array name or array type sections.
# vxdmpadm config check file=filename
DMP displays no output if the configuration check is successful. If the file contains errors, DMP displays the errors. Make any required corrections until the configuration file is valid. For example, you may see errors such as the following:
VxVM vxdmpadm ERROR V-5-1-0 Template file 'error.file' contains following errors: Line No: 22 'dmp_daemon_count' can not be set to 0 or less Line No: 44 Specified value for 'dmp_health_time' contains non-digits Line No: 64 Specified value for 'dmp_path_age' is beyond the limit of its value Line No: 76 'dmp_probe_idle_lun' can be set to either on or off Line No: 281 Unknown arraytype
# vxdmpadm config load file=filename
During the loading process, DMP validates each section of the template. DMP loads all valid sections. DMP does not load any section that contains errors.
