Mount Point Packages for Snapshot Images
A snapshot is a frozen image of an active file system that does not change when the
contents of target file system changes. On cluster file systems, snapshots can be created
on any node in the cluster, and backup operations can be performed from that node.
The snapshot of a cluster file system is accessible only on the node where it is created;
the snapshot file system itself cannot be cluster mounted.
For details on creating snapshots on cluster file systems, see the Veritas Storage Foundation
Cluster File System Installation and Administration Guide posted at www.hp.com/go/
hpux-serviceguard-docs.
The following example illustrates how to create a snapshot of the /tmp/logdata/
log_files file system.
1. Create local storage on which to place the snapshot.
vxdg init dg1 c4t1d0
vxassist -g dg1 make vol1 100m
vxvol -g dg1 startall
2. Associate it with the cluster.
cfsmntadm add snapshot dev=/dev/vx/dsk/dg1/vol1 \
/tmp/logdata/log_files /local/snap1 ftsys9=ro
Package name "SG-CFS-SN-1" was generated to control the resource
Mount point "/local/snap1" was associated to the cluster
cfsmount /local/snap1
