I have two identical servers (Running Solaris) connected to a Sun Storedge 3100 through SCSI. I want to make a cluster out of them. The storage will be used to store a database.
The Storage works fine when I connect it to just one server, but when I connect it to both servers it starts to perform very badly. It takes 20 minutes to display the format output, and even then it sees some disks as unformatted. This may be due to the fact that both servers are trying to access the same disks at the same time.
Is there a way to restrict access to in-use disks? From what I've heard there should be a software that comes with Solaris that does this, but I have not been able to find details about it.
Any help would be greatly appreciated.
