When working with SnapDrive, you must be aware of the limitations related to LUNs.
You can run the snapdrive config check luns command when you create LUNs on these hosts. This command allows you to determine how many LUNs you can create.
The colon is allowed between the components of a long Snapshot copy name or between the storage system name and storage system volume name of a LUN. For example, toaster:/vol/vol1:snap1 is a typical long Snapshot copy name, while toaster:/vol/vol1/lunA is a typical long LUN name.
