This SOM disables the HDP Rebalance function and
the HDT Tier relocation function which allow the
drives of all ECC Groups in the pool to share the load.
Mode 749 = ON:
The HDP Rebalance function and
the HDT Tier relocation function are disabled.
Mode 749 = OFF (default):
The HDP Rebalance
function and the HDT Tier relocation function are
enabled.
Notes:
1.
This SOM is applied when no change in
performance characteristic is desired.
2.
When a pool is newly installed, the load may be
concentrated on the installed pool volumes.
3.
When 0 data discarding is executed, load may
be unbalanced among pool volumes.
4.
Pool VOL deletion while this SOM is set to ON
fails. To delete pool VOLs, set this SOM to OFF.

Mode 757 applies to the sites where outputting
the In-band audit logs is not needed.
2.
When this SOM is set to ON:
■
There is no access to SM for the In-band
audit logs, which can avoid the
