[klathon]

What exactly does the "SCSI Bus Sharing" mean?

i can't understand the description below:

Under what circumstances are these three methods used?

i did a test

share1 and share2 have the Same configurations:

scsi controller 1 set "SCSI Bus Sharing"="None" with disk 3(10GB),

scsi controller 2 set "SCSI Bus Sharing"="Physical" with disk 2(8GB).

the two disks in the two OS looks like same,  is there any difference between them?

when should I use the "none","physical" ,"virtual"?

in this kb, it let me use the "none"

VMware Knowledge Base

English is not my native language, please forgive me.

All of your questions can be answered with a couple of Google searches. Have you done that?

[klathon]

sorry, I've used some search engines,about 3 hours, but i didn't found the relevant answer.

We were restricted to use Google for some years, so I gradually lost the habit of using Google.

now, I think I should get a VPN.

thanks.
