Tiering for
Mainframe 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.
