For the information of setting timing, refer to the
procedure for blocked pool volume recovery in the
Maintenance Manual.
2. The processing time increases with increase in pool
capacity.
Estimate of processing time:
Processing time (minutes) = ceiling(pool capacity
(TB)/40) + 5
ceiling: The value enclosed in ceiling( ) must be
rounded up to the nearest whole number.
The processing finishes early if there is less capacity of
allocated pages.
3. Do not change this SOM setting during LDEV format for
a virtual volume whose capacity saving setting is
Compression. If the setting is changed, the processing
cannot be performed correctly and may end abnormally
depending on the timing.
4. This SOM is effective only for LDEV format for a virtual
volume whose capacity saving setting is Compression,
so that there is no side effect in relation to user data,
but the processing may take more time than that when
this SOM is set to OFF depending on the pool capacity.
Therefore, basically do not use this SOM for cases other
than pool volume blockage recovery.
1118 Open This SOM is used to disable the ENC reuse function.
Mode 1118 = ON: When a failure occurs in the Expander
chip mounted on a controller board (CTLS, CTLSE) or an ENC
board, the reuse function does not work but SIM=CF12XX is
reported and the ENC is blocked.
Mode 1118 = OFF (default): When a failure occurs in the
Expander chip mounted on a controller board (CTLS, CTLSE)
or an ENC board, the reuse function works.
If the ENC is reusable, SIM=CF12XX and then CF14XX are
reported, and the ENC is reused.
If the ENC is not reusable, SIM=CF12XX is reported, and the
ENC is blocked.
Note: The ENC reuse function is enabled as default. This
SOM is applied when you want to disable the ENC reuse
function.

1119 Deduplication
and Compression
This SOM is used to downgrade the microcode as follows
while capacity saving is enabled:
• VSP G1000, VSP G1500, VSP F1500: From
80-05-05-00/00 or later to 80-05-01-00/00 or later
• VSP Gx00 models, VSP Fx00 models: From 83-04-03-
x0/00 or later to 83-04-01-x0/00 or 83-04-02-x0/00
New control information is added with 80-05-05/83-04-03 for
the inflow control processing when capacity saving is
enabled. However, it must be guaranteed that the area is not
used when the microcode version is 80-05-01/83-04-01 or
later. This SOM disables the control information added with
80-05-21/83-04-21 when capacity saving is enabled to
enable microcode downgrade.
