You can use the snapdrive snap connect command for connecting to a Snapshot copy that contains storage entities other than LUNs. This command cannot be used when destination names you provide are currently in use or, there is a file system name that is used as a mountpoint.
SnapDrive for UNIX clones the LUNs you specify and connects them to a new location.
The following command line connects a disk group and uses the default names as the destination names (that is, it creates them from the source names):
# snapdrive snap connect -vg vg1 -snapname filer1:/vol/vol1:vg1snapshot connecting vg1: LUN copy vg1_lun1_0 ... created (original: filer1:/vol/vol1/vg1_lun1) mapping new lun(s) ... done discovering new lun(s) ... done Importing vg1
# snapdrive snap connect -lvol vg1/vol1 vg1copy/vol1copy -snapname filer1:/vol/vol1:vg1snapshot connecting vg1: LUN copy vg1_lun1_0 ... created (original: filer1:/vol/vol1/vg1_lun1) mapping new lun(s) ... done discovering new lun(s) ... done Importing vg1copy
# snapdrive snap connect -fs mnt/fs1 /mnt/fs1copy -destvg vg1copy \ -fs /mnt/fs2 /mnt/fs2copy -destlv vg1copy/vol2copy -destvg vg1copy \ -snapname filer1:/vol/vol1:vg1snapshot connecting vg1: LUN copy vg1_lun1_0 ... created (original: filer1:/vol/vol1/vg1_lun1) LUN copy vg1_lun2_0 ... created (original: filer1:/vol/vol1/vg1_lun2) mapping new lun(s) ... done discovering new lun(s) ... done Importing vg1copy
# snapdrive snap connect -lvol mnt/fs1 -snapname filer1:/vol/vol1:vg1snapshot \ -autoexpand connecting vg1: LUN copy vg1_lun1_0 ... created (original: filer1:/vol/vol1/vg1_lun1) LUN copy vg1_lun2_0 ... created (original: filer1:/vol/vol1/vg1_lun2) mapping new lun(s) ... done discovering new lun(s) ... done Importing vg1
# snapdrive snap connect -fs mnt/fs1 -snapname filer1:/vol/vol1:vg1snapshot \ -autorename connecting vg1: LUN copy vg1_lun1_0 ... created (original: filer1:/vol/vol1/vg1_lun1) LUN copy vg1_lun2_0 ... created (original: filer1:/vol/vol1/vg1_lun2) mapping new lun(s) ... done discovering new lun(s) ... done Importing vg1_0
In the following example, file system 1 (fs1) resides on storage system1, and file system 2 (fs2) resides on storage system1 and also on storage system2, which is the partner storage system. File system 3 (fs3) resides on storage system1, partner storage system 2, and storage system 3, which is not part of the HA pair. An additional file system, fs4, resides entirely on storage system 4.
snapdrive snap create -fs /mnt/fs1 /mnt/fs2 /mnt/fs3 /mnt/fs4 -snapname fs_all_snap
snapdrive snap connect -fs /mnt/fs1 /mt/fs2 -snapname fs_all_snap
snapdrive snap connect -fs /mnt/fs4 -snapname fs_all_snap
SnapDrive for UNIX cannot connect fs3 on the destination storage system, because this file system resides on storage system1, storage system 2, and storage system 3.
