Re: 9405-520 DIsk Location Resource Questions and SRC Code

Hi Jim,


I only removed/replaced disk units from the P2 and P3 bays. I did not mess with internal cables, but the system was transported. I will double check them. I do suspect they are intact or the disks oddly reporting to P1 instead of P2 would not be reporting at all. Disks in P3 report correctly.


Thanks,


Shawn

Did you mess with the cables? Be sure they are in tight, I've seen CEs not push them in tightly.

Shawn,

Possibly the DASD controller retained some info, probably should have "flushed the cache".
You may still want to try this, see if the error disappears.

Hello,


I'd like to follow up with some additional details to clarify. I think I have caused misconfigured hardware, hopefully not damaged.


Both P2 and P3 Backplanes are type 28D2. Misconfigured Backplane P2 has no associated hardware resources (seemingly causing attached disks to report as if on P1). Working Backplane P3 shows "Device Services" as the hardware resource and then the 4 disks properly located at P3.


Another odd symptom of P2 is the 4 disks have solid green power/activity lights, while the normally configured disks on P3 do not. Even with NO disks inserted into P2, it still kept these planar green indicators lit solid.


I initially thought an IPL of LIC optical media and initialize would auto detect and configure these things, but this is where I ended up so far. I don't know what else to do now. I keep researching and reading.


Thanks,

Shawn
