Table 9-1
Commands for controlling instant snapshot synchronization
DescriptionCommand
Pause synchronization of a
volume.
vxsnap [-g diskgroup] syncpause \
vol|vol_set
Resume synchronization of a
volume.
vxsnap [-g diskgroup] syncresume \
vol|vol_set
Start synchronization of a volume.
The -b option puts the operation
in the background.
vxsnap [-b] [-g diskgroup] syncstart \
vol|vol_set
Stop synchronization of a volume.vxsnap [-g diskgroup] syncstop \
vol|vol_set
Exit when synchronization of a
volume is complete. An error is
returned if the vol or vol_set is
invalid (for example, it is a
space-optimized snapshot), or if
the vol or vol_set is not being
synchronized.
Note: You cannot use this
command to wait for
synchronization of reattached
plexes to complete.
vxsnap [-g diskgroup] syncwait \
vol|vol_set
The commands that are shown in Table 9-1 cannot be used to control the
synchronization of linked break-off snapshots.
The vxsnap snapwait command is provided to wait for the link between new
linked break-off snapshots to become ACTIVE, or for reattached snapshot plexes
to reach the SNAPDONE state following resynchronization.
See “Creating and managing linked break-off snapshot volumes” on page 378.
See “Reattaching an instant snapshot” on page 385.
See “Reattaching a linked break-off snapshot volume” on page 386.
Improving the performance of snapshot synchronization
The following optional arguments to the -o option are provided to help optimize
the performance of synchronization when using the make, refresh, restore and
syncstart operations with full-sized instant snapshots:
