new hard disk not detected on openboot
hello guys,
would like to request help if there are any settings i need to enable for a netra t1 to detect the new hard disks that were added on a dell disk array. the netra t1 is able to detect scsi hds 1-3 but not the 8-11. have checked netra t1 manual and it says that it supports both narrow and wide scsi. probe scsi only shows the following disks:
/pci@1f,0/pci@1,1/scsi@2
Target 0
Unit 0DiskSEAGATE ST318404LSUN18G 8590
Target 1
Unit 0DiskSEAGATE ST318406LC8A03
Target 2
Unit 0DiskSEAGATE ST318406LC8A03
Target 3
Unit 0DiskSEAGATE ST318406LC8A03
the new disks are of the same model. any help is greatly appreciated.

Hello,

...

This is an incomplete output of probe-scsi. Which of these disks are internal (maybe only ID 0?) ?
Set auto-boot? to FALSE at the ok-prompt. Temporarily insert one of the new disks in the slot of one of the detected disks (e.g. ID3). Is the disk now detected at the OBP ? If it is, there is something wrong with the external chassis.
I assumed that this is a Netra T1 AC200/DC200 with only a single channel SCSI controller.

Hi Michael,
Tried what you adviced and it managed to detect the other disks. I think i found the problem, there are 2 scsi ports on the dell array for redundancy according to their doc. I tried to switch the scsi connector to the other port then it detected the 8-11 disks not the 1-3. Since netra t1 only have one scsi controller, ill just connect the other port on another server and use the disks from there. Thanks for the help =).
