FC60 one of the 2 controllers missing

[meekrob]

Hi All,

can anyone help me with the following issue that im having?

In fact, we have an FC60 controller with 3 SC10 arrays conncted to 2 rp7440 servers.

Suddenly, a number of LUNs get disappeared from both servers and when typing "amdsp -a array1" im just getting in the output LUNs connected to controller A only eventhough the output is showing the below info for ctrl B:

Total capacity of LUNs on controller B = 0.0 MB

......

Information for Controller B - 001200A0B80952A4:
      Controller Status   = GOOD
      Controller Mode     = ACTIVE

.......

Array Controller Subsystem:
       Controller A: GOOD
       Controller B: GOOD

>amdsp -a array1

LUN       Status        Capacity   Ctrl  RAID  Segment  Disks
   ---  -----------------  ---------  ----  ----  -------  -----
     0  OPTIMAL              67.8 GB   A     5         16  1:0
                                                                                       3:0
                                                                                       5:0

     2  OPTIMAL             169.4 GB   A     5         16  1:1
                                                                                        1:2
                                                                                        3:1
                                                                                        3:2
                                                                                        5:1
                                                                                        5:2

     4  OPTIMAL              67.8 GB   A     5         16  2:3
                                                                                      4:3
                                                                                      6:3

from the above output, we can only see controller A's LUNs only (and LUNs 1 and 3 on controller B are missing)

Any idea / hint on this situation?

Thanksin advance
