Hi there,
I have two SunBlade 2000s that I want to connect to a single D1000. I am told that I need to do a split bus mode. I don't really understand what that means. Does that mean that half of the storage disks will be assigned to one host and the others to the other host? How do I get that accomplished? I have already connected the SCSI cables on both hosts from the D1000, now do you guys know what the next step is? Please help. Thank you!
you are done.... one cable from each host to each half on the d1000. and don't forget to use a terminator (active) for each bus. also you need hvd scsi controller in your blades to connect them to a d1000. the blades have only se scsi controller onboard!
if this is done, just run "devfsadm" on your hosts to make the disks visible. maybe you need to edit the file /kernel/drv/sd.conf to have more lun's on your system.
hth,
DN2
When I looked at sd.conf on both hosts, I see that they are both targetted at 7. Should I change one of them to be different? After I connected both SunBlades to the D1000, I did try devfsadm but the disks do not show up. Am I missing something here?
can u see the disks at the "ok" prompt?
ok setenv auto-boot? false
ok reset-all
ok probe-scsi-all
if you don't see the disks there, you might not have the right scsi controller in your hosts.
When I did probe-scsi-all, what I got is the following.
{0} ok probe-scsi-all
/pci@8,600000/SUNW,qlc@4

Unit 0 Removable Read Only device TOSHIBA DVD-ROM SD-M14011009
Earlier I changed host 1's scsi-initiator-id to 6 and the other one (host 2) remained 7. When I logged back in and did devfsadm, I saw no difference so i changed host 1's scsi-initiator-id back to 7.
and you are sure you have the right scsi controller? post the output of "prtdiag -v".
For host 2 as an example, this is what I got.

looks like you have fcal hbas but no hvd scsi controller....
oh I do not see anything about bus. What I see is CPU, IO Devices, Memory Configuration. In addition, what I have is an 8-disk D1000. On the Option Switch at the back. I set it to
1 - down
2 - down
3 - up
4 - down
5 - down
I am not sure if that is the right setting or if that has anything to do with the current issue that I have?
look at the documentation for the d1000....
docs.sun.com an sunsolve.sun.com
but without the right scsi hba you won't see your d1000!
Oh wait a minute, should I do the prtdiag on the D1000 itself or one of the two hosts? I will look into the documentation.
can you make a photo from the backside of one of your hosts with all the cableing?
btw. prtdiag on the host, you can't run it on the d1000...
So what i did was to connect each of the SCSI cable from the D1000 to the SCSI connector located next to the parallel connector just below the two serial connectors. I am trying to figure out if that was the right connector that I was supposed to connect the cables to or if I have to install a separate PCI card with SCSI connectors. The SCSI connector is an ULTRA SCSI, 68-pin. I found a diagram from document 816-3216-10, p. 4 found in
i told you allready in the first post:
you need a hvd scsi controller! the onboard controller is a se scsi controller! the onboard controller will NOT work with a d1000!
Hmm is the hvd scsi controller then a PCI card that I will need to install on both SunBlade 2000s?
thats the only way...
Sun Blade 2000 - Full Components List
X6541A Dual Differential Ultra/Wide SCSI (UDWIS/P)(HVD)
I will try that. I will need a SCSI cable that has one 68-pin Ultra SCSI connector on one end and the other end is the smaller one, right?
you got it man 
OH MY GOD!!! I DID IT!!!!!!! Thank you so much!!!!!!!
