Connecting to Snapshot copies of shared storage entities other than LUNs

You can use the snapdrive snap connect command to connect to a Snapshot copy of shared storage entities other than LUNs.

Steps
  1. Enter the following command:

    snapdrive snap connect fspec_set [fspec_set…​] -snapname long_snap_name [-devicetype shared] [-split]

    In this syntax, fspec_set is: {-dg | -fs}_src_file_spec_ [dest_file_spec ] [-destdg dgname]

The following example connects to a Snapshot copy that contains shared storage entities on an originating host cluster. The operation is executed from the non-cluster-master node, but the command is shipped to the master node and executed:

# snapdrive snap connect -fs /mnt/sfortesting /mnt/sfortesting2 -
snapname f270-
197-109:/vol/vol2:testsfarcsnap -devicetype shared -autorename
Execution started on cluster master: sfrac-57
connecting sfortesting_SdDg:
LUN copy sfortesting_SdLun_0 ... created
(original: f270-197-109:/vol/vol2/sfortesting_SdLun)
mapping new lun(s) ... done
discovering new lun(s) ... done
Connecting cluster node: sfrac-58 mapping lun\(s\) ... done

The following example connects to a Snapshot copy that contains shared storage entities on a non-originating host cluster. The operation is executed from the non-cluster-master node, but the command is shipped to the master node and executed:

# snapdrive snap connect -fs /mnt/sfortesting -snapname f270-197-
