2 cluster services sharing the same SCSI bus

Hi Gurus,

I wish to seek opinions on the ff configuration:

a) Environment is Tru64 UNIX V4.0E and TruCluster V1.5
b) DiskA belong to ServiceA which normally runs on ServerA
c) Likewise, DiskB belongs to ServiceB which normally runs on ServerB

Question:

If I place DiskA and DiskB on the same shared SCSI bus, will I be facing a
lot of troubles in the future? I would assume if ServerA is accessing DiskA,
ServerB can't access DiskB. On such situation, will my error logs be filled
with error messages?

Is it preferable that if I only have one shared scsi bus to run both
ServiceA and ServiceB on the same server (assuming the server has enough
horsepower)? or it doesn't make any difference at all?

Thanks in advance for any opinions.


Best Regards,

Carlos Chua
