d130 multi hosted on Netra t1 105

Hi Guru's,

I want to setup an Sun Cluster for testing purposes and have the following

hardware to use :

- 2xNetra t1 105 1GB/2x18GB/1Gigabit Adapter (for Interconnect)

- Netra st d130 Storage (3x18GB). (just one)

When I try to setup the d130 I get an SCSI-Error.

I have changed the scsi-initiator-id from one host from 7 to 6 to avooid

conflicts, but still it fails.

I did the same with 2 220R and a MultiPack as Storage and with this

configuration it worked.

So, now here are my questions :

Is the configuration working with the 220R because the 220R has 2 channels on the SCSI bus and therefore it can handle such configueation. Unfortunatelly i am not very familiar with SCSI.

It looks like the internal drives (SCSI 0 and 1) are causing the Problem with the Netras. I think it has to do with the fact that the Netras does not have 2 SCSI channels - pls correct me if i am wrong!

Can you image that such a configuration (2x105 + d130) works?

Do you think I need another SCSI-Adapter (to have 2 channels)?

Is it possible to change the SCSI-ID of the internal drives (maybe this would avoud the conflict of the ID's) ?

Every hint is verya, very welcome!!!

Please let me know what information you need to be abele to help me further - I will provide this information asap!

Thanks in advance for your valueable feedback!

If your d130 is like mine, it has a switch on the back to change the scsi id's from 2-3-4 to 10-11-12... this might solve the problem....harold

Hi!

Thanks for your reply!

The d130 is currently set to assign SCSI-ID's 10,11,12!

When I just connect one Server to the d130 and so a probe-scsi-all the System can find 2 internal (Netra t1 105) and 3 external (d130) disks on the SAME controller. When I do the same on the other node, I also get 5 disks (2+3) on the SAME controller.

The internal disks always have SCSI-Id 0 and 1.

That worries me since when I connect both Servers on the d130, the other node can not boot - which is imho because SCSI.-ID 0 and 1 (the internal disks) are assigned twice and the scsi-chain gets confused.

Normally a system distinguishes between the internal SCSI-chain and the external chain - pls. correct me if i am wrong!

It looks like an Netra t1 105 has all on one chain and therefore it conflicts with the internal disks ?

Am i talking bullshit or can it be that my assumption is right ?

Is there a way to change the SCSI-ID of the internal disks?

Di I have to install another SCSI-Adapter to be able to distinguish between internal end external drives and to avoid conflicts?

Please let me know if you need futher information about setp and/or configuration ...

Were you ever able to get this to work? I'm trying the exact configuration, but I can't figure out how to get the second node attached to the D130. Is it possible to connect to hosts to a D130?Thanks,Jeff
