- This question is raised from time to time.
-
- Yes, two (or more) systems can be on the same scsi bus as scsi disk and
- tape drives. As long as the scsi requirements are met - cable lengths,
- termination and type - the devices can share the scsi bus.
-
- The question should be - Are there any O/S' that will allow the sharing of
- file systems? It would not make sense for two hosts to go about treating
- shared disks as if they owned the device. Data would be destroyed pretty
- quickly.
-
- On the issue of tape devices, however, O/S' tend to give exclusive usage
- to an application. In this way, tape drives can be shared much more easily.
-
- Disks can be best shared by having two (or more) partitions on a disk. Each
- host "owning" it's own file system.
-
- Hope that this helps.
