SUMMARY: Will device names change when adding a D1000 to an UE450 ?

Hi,

Thanks to Matthew Stier, Darren Dunham, Jay Lessert, and Kris Briscoe for 
their answers.

Short answer (and consensus) is: no.


A while ago, I asked:

> I will soon need to add a dual port SCSI board with a D1000 storage device
> to a Sun Ultra Enterprise 450, running Solaris 2.6 with SDS.
>
> The machine currently has 20 internal disk slots (18 full) and two external
> D1000 devices, each with 12 disks.  The PCI slot layout is as follows:
> 10: empty
>  9: empty
>  8: empty
>  7: Sun Gigabit ethernet board
>  6: dual port SCSI board connected to external D1000
>  5: dual port SCSI board connected to internal disk rack
>  4: dual port SCSI board connected to external D1000
>  3: empty
>  2: empty
>  1: dual port SCSI board connected to internal disk rack
>
> The dual port SCSI boards are all Symbios 53c875.

> When I add in the new PCI-SCSI board, should I worry that it might change the

In Matthew's words:
SunOS keeps a flat file database of devices, mapping their OBP path, to an
OS instance.  The file is /etc/path_to_inst, and unless you remove the instances
for existing devices, you won't run into any conflicts.

> Any words of advice on which slot to use for the new board ?

None received.
