Set Volume-Exc - Fujitsu Eternus DX100 S3 User Manual

Chapter 3 Configuration Settings and Display
3.2 Volume Management > set volume-exc

set volume-exc

This command enables or disables the Extreme Cache (EXC) function for each volume.
• This command cannot be performed for the ETERNUS DX100 S3/DX200 S3 or the ETERNUS DX200F. The
EXC function is not used regardless of the setting of each volume when the EXC function is disabled for
the ETERNUS DX. Whether the EXC function is enabled for a volume can be checked by using the "show
volumes mode detail" command.
• The EXC function is disabled for volumes when they are moved to a RAID group or a TPP that consists of
SSDs by RAID Migration. When volumes are moved from a RAID group or a TPP that consists of SSDs to a
RAID group or a TPP that consists of disks, the EXC function is enabled for the volumes. When volumes are
moved between RAID groups or TPPs that consist of disks, whether the EXC function is enabled or dis-
abled remains unchanged for the volumes.
• The EXC function for FTVs is controlled by a software application. (The EXC function is available for the FTV
even if an FTRP contains an FTSP that consists of SSDs.)
■ Syntax
set volume-exc {-volume-number
-mode {enable|disable}
■ Parameter
-volume-number
or
-volume-name
or
-all
volume_numbers
This parameter specifies the volume that the setting is changed for. When the "-all" parameter
is specified, the settings are changed for all of the volumes that the EXC function is available
for.
The "-all" parameter applies the change in settings to all of the Open volumes, Standard vol-
umes, WSVs, and TPVs (this does not apply when the volume belongs to a RAID group that con-
sists of SSDs or a TPP that consists of SSDs).
This parameter allows multiple volume numbers and a range of volume numbers to be
specified. For details, refer to
This parameter allows only a single volume name to be specified.
This parameter can be used for Open volumes, Standard volumes, WSVs, and TPVs that do not
belong to a RAID group that consists of SSDs or a TPP that consists of SSDs. If a volume that
cannot be set is specified for a volume number or a volume name, this command results in an
error.
