7. Run deduplication on the flexible volume. These causes the change log to be processed, fingerprints to
be sorted and merged, and duplicate blocks to be found.
r200-rtp01> sis start /vol/VolArchive
The deduplication operation for "/vol/VolArchive" is started.
8. Use sis status to monitor the progress of deduplication.
r200-rtp01> sis status /vol/VolArchive
Path State Status Progress
/vol/VolArchive Enabled Active 9211 MB Searched
r200-rtp01> sis status /vol/VolArchive
Path State Status Progress
/vol/VolArchive Enabled Active 11 MB (0%) Done
r200-rtp01> sis status /vol/VolArchive

r200-rtp01> sis status /vol/VolArchive

r200-rtp01> sis status /vol/VolArchive

/vol/VolArchive Enabled Idle for 00:00:07
9. When sis status indicates that the flexible volume is once again in the Idle state, deduplication has
finished running, and you can check the space savings it provided in the flexible volume.
r200-rtp01> df -s /vol/VolArchive
Filesystem used saved %saved
/vol/VolArchive/ 24072140 9316052 28%
That’s all there is to it.
2.6 CONFIGURING DEDUPLICATION SCHEDULES
It’s best to set up a schedule for deduplication so that you don’t have to run it manually each time. This
section provides some specifics about configuring schedules with deduplication.
The sis config command is used to configure and view deduplication schedules for flexible volumes. The
usage syntax is shown below.
r200-rtp01> sis help config
sis config [ [ -s schedule ] <path> | <path> ... ]
Sets up, modifies, and retrieves the schedule of deduplication volumes.
Run with no arguments, sis config returns the schedules for all flexible volumes that have deduplication
enabled. The following example shows the four different formats the reported schedules can have.
toaster> sis config
Path Schedule
/vol/dvol_1 -
/vol/dvol_2 23@sun-fri
/vol/dvol_3 auto
/vol/dvol_4 sat@6
The meaning of each of these schedule types is as follows:
On flexible volume dvol_1, deduplication is not scheduled to run.
