What is this storage?
:frusty: I am using RedHat 4.0 ES on two JNCS 32 bit servers to build an Oracle11g test cluster. I am using a Nexstor RC 8F fibre channel disk array as the shared storage (it has dual fibre channel adapters, makes it easy to hook to two systems). The Nexstor uses HSSDC to DS9 type fibre-copper connectors.
When I place 4 drives in the 8-drive array it works just fine, both servers can see all four drives. The problem comes when I try to add more than four disk drives, as soon as I place the fifth drive into the array it errors with a failed connection light even thoug the POST shows no problems with the array. The JNCS HBAs will startup but can't see any of the disks in the array. Once I remove the additional drive(s) back down to the original 4 the problem goes away.
There are two 8 place dip switches on the Intelligent cabinet controller card, as far as I can tell they are the only accessible settings other than through the LCD display. The are currently set with the two right most switches on on the first switch (labeled R10 and R9) and the third switch from the left side on (labeled R16) the second switch on.
If anyone has any experience with the NexStor RC 8F and is famiiar with the needed switch settings I would sure appreciate the help. If anyone has the manual in PDF format (not the NexStor 8L series or FL, I have that manual and it is useless for this model) that would be great. As far as I can tell the nearest thing to this is the NexStor 18F in that it has the same fibre channel setup, but looking at its switch settings I cannot find this one so I assume they are different.
Anyway, any help would be greatly appreciated!
