StorEdge D1000

This time ... read the fine manual ... just for a change.

Just in case any of you find yourselves installing a Sun StorEdge D1000 at some point in time, I would like to recommend that you get hold of the essential pdf file (805-2624-12) attractively called "SunStorEdge (TM) A1000 and D1000 Installation, Operations, and Service Manual" (look on the SunDocs site).

Why?

Because it has the correct settings for the incy-wincy-teeny-weeny dip-switch settings.

The very clear and exact instructions that come attached to the first generation D1000 (the one with only 8 disks instead of 12) suggest that the correct settings are switch 1 down and switch 2 up to give the addresses as targets 0, 1, 2, 3, 8, 9, a and b. If you split the D1000 you change switch 2.

This is wrong.

Very wrong.

The rightmost (as viewed from the back) dipswitch (1) controls the right hand array (as viewed from the front). Up gives 8, 9, a and b. Down gives 0, 1, 2 and 3. The next switch (2) controls the left hand side (up for 8, 9, a and b; down for 0, 1, 2 and 3).

Clear now? Probably not. Just follow the manual and completely ignore the instructions on the D1000 itself :-)
