When this SOM is ON, the frequency of progress update of
disconnection is changed.
Mode 589 = ON:
For each external volume, progress is
updated only when the progress rate is 100%.
Mode 589 = OFF (default):
Progress is updated when the
progress rate exceeds the previous level.
Notes:
1.
Set this SOM to ON when disconnecting an external
volume while the specific host IO operation is online
and its performance requirement is severe.
2.
Whether the disconnecting status for each external
volume is progressed or not cannot be confirmed on
Device Manager - Storage Navigator (It indicates “-
“until just before the completion and at the last it
changes to 100%).

Allows you to slow the initial copy and resync operations
when the write-pending rate on the RCU exceeds 60%.
Mode 689 = ON:
The initial copy and resync copy operations
are slowed down when the Write Pending rate on RCU
exceeds 60%.
If the CLPR write pending rate where the initial copy target
secondary volume belongs to is not over 60% but that of MP
PCB where the S-VOL belongs to is over 60%, the initial copy
operation is slowed down.
Mode 689 = OFF (default):
The initial copy and resync
copy operations are not slowed down when the Write Pending
rate on RCU exceeds 60% (the same as before).
