Some controllers show NVRAM11 DIMM in unexpected order

Applies to

• AFF A900
• FAS9500
• NVRAM11
  • NV-DIMM

Issue

The NVRAM11 adapter contains two NVRAM 11 DIMM (NVDIMM) slots

• Those slots are numbered 1 and 2 on the adapter itself and the FRU map on the lid of the adapter
• Some ONTAP output might display an unexpected sequence of those two NVDIMM modules

Running the following commands will display the output in this order:

• ::> system node run -node * -command "sysconfig -M"

!NVRAM11 DIMM!CE-04-2334-BBBBBBBB!!M393A4G40AB3-CWE!

• ::> system controller fru show-manufacturing-info -node * -description "NVRAM11 DIMM"
