Bart,
> * Copying must be supported not only within a single storage device but > also between storage devices. Identifying which devices to permit copies between has been challenging. That has since been addressed in T10. > * VMware, which uses XCOPY (with a one-byte length ID, aka LID1). I don't think LID1 vs LID4 is particularly interesting for the Linux use case. It's just an additional command tag since the copy manager is a third party. > * Microsoft, which uses ODX (aka LID4 because it has a four-byte length > ID). Microsoft uses the token commands. -- Martin K. Petersen Oracle Linux Engineering -- dm-devel mailing list dm-devel@redhat.com https://www.redhat.com/mailman/listinfo/dm-devel
