By setting the mode to ON, HDT monitoring data is 
collected even if the pool is a HDP pool.
Mode 937 = ON:
HDT monitoring data is collected even if the pool is 
a HDP pool.
Only Manual execution mode and Period mode are 
supported.
Mode 937 = OFF (default):
HDT monitoring data is not collected if the pool is a 
HDP pool 
Notes:
1. The mode is applied when HDT monitoring data 
collection is required in HDP environment.
2. When HDT is already used, do not set the mode 
to ON.
3. For HDT monitoring data collection, shared 
memory for HDT must be installed.
4. If monitoring data collection is performed 
without shared memory for HDT installed, an 
error is reported and the monitoring data 
collection fails.
5. Before removing the shared memory for HDT, 
set the mode to OFF and wait for 30 minutes.
6. Tier relocation with monitoring data collected 
when the mode is set to ON is disabled.
7. When HDP is converted into HDT (after 
purchase of PP license), the collected 
monitoring data is discarded.
