Oracle RAC instructor... They offered a class in Florida a few weeks = back, I hear they had that set up with two PCs (I assume Dells) and external = disks but I don't have any more info. Sounds like a great way to learn the product. The type of drive you use is important for the firewire setup, I read somewhere that not all drives can be recognized.

I still have problem to make it work. I follow documents on=20 http://www.puschitz.com/ and still can NOT make firewire hard disk recognize by redhat. I did discuss with ORACLE RAC instructor and he told me use SCSI external disk instead of Firewire. He said SCSI disk far more stable than IDE (firewire). he said "ORACLE LINUX/RAC" course also use SCSI disk wirh United LINUX (will change to redhat AS3.0 soon). My problem are: 1. on AS 2.1 UP5: . load firewire driver successful . lsmod and lspci all indicate firewird adapter work . rescan-scsi-bus.sh can NOT find disk. . unload/reload firewire modules and rescan all make =20 no difference.=20 2. on AS 3.0 UP3 (2.4.21-20) . newest Redhat kernel (2.4.21-20 AS 3.0 UP3) does NOT =20 understand firewire. I download =20 kernel-2.4.21-15.ELorafw1.i686.rpm from ORACLE site and triied to install it and got =20 error messages "current kernel version newer than =20 it". (rpm -ivh kernel-2.4.21-15.ELorafw1.i686.rpm) Can you tell me how cah you make 2.4.21-20 work without use ORACLE driver?
