1. like the consumers option with create index or update stats, is there a similar option for reorg?
No. That being said, You could get a level of parallelism if you used semantic partitioning where you reorg each partition independently.
2. will consumers option work on non-raid disks? one of my collegues told me (I think) that because the disks were on san, Sybase couldn't know if they were not raid or not (or not striped), or something to that effect. and so will consumers option work even on non raid disks? any opinions?
ASE has no knowledge what type of disk is being used. ASE parallelism is independent of whatever disk subsystem you may or may not have.
3. is there any other way to bind parallelism to a particular transaction - like reorg for instance - and not let other processes hijack the worker processes meant for that function?
Possibly using the resource governor. If you assigned the user to a high priority group, .. Maybe. AFAIK, no.
