Displaying snapshot information

The vxassist snapprintcommand displays the associations between the original volumes and their respective replicas (snapshot copies):

# vxassist snapprint [volume]

Output from this command is shown in the following examples:

# vxassist -g mydg snapprint v1

V  NAME         USETYPE      LENGTH
SS SNAPOBJ      NAME         LENGTH     %DIRTY
DP NAME         VOLUME       LENGTH     %DIRTY

v  v1           fsgen        20480
ss SNAP-v1_snp  SNAP-v1      20480      4
dp v1-01        v1           20480      0
dp v1-02        v1           20480      0

v  SNAP-v1      fsgen        20480
ss v1_snp       v1           20480      0

# vxassist -g mydg snapprint v2

V  NAME         USETYPE      LENGTH
SS SNAPOBJ      NAME         LENGTH     %DIRTY
DP NAME         VOLUME       LENGTH     %DIRTY

v  v2           fsgen        20480
ss --           SNAP-v2      20480      0
dp v2-01        v2           20480      0

v  SNAP-v2      fsgen        20480
ss --           v2           20480      0

In this example, Persistent FastResync is enabled on volume v1, and Non-Persistent FastResync on volume v2. Lines beginning with v, dp and ss indicate a volume, detached plex and snapshot plex respectively. The %DIRTY field indicates the percentage of a snapshot plex or detached plex that is dirty with respect to the original volume. Notice that no snap objects are associated with volume v2 or with its snapshot volume SNAP-v2.

If a volume is specified, the snapprint command displays an error message if no FastResync maps are enabled for that volume.
