Fujitsu M10-1: Changing Memory Configurations Considerations (Doc ID 1981987.1)

Last updated on MAY 02, 2016

Applies to:

Fujitsu M10-1 - Version All Versions and later
Information in this document applies to any platform.

Symptoms

Fujitsu M10-1 system can't see sections of memory after physically altering the memory configuration.

Changes

System (OVM) cannot identify sections of memory, when:

Modifying memory configuration means either:

  1. Number of DIMMs in either group (group-A / B) is changed from 4 to 8, or 8 to 4, or
  2. Capacity of 8 DIMMs in either group (group-A / B) is changed from the same capacity to the different capacities (such as “eight 8GB DIMMs” to “four 8GB DIMMs and four 16GB DIMMs”), or from the different capacities to the same capacity)

Because M10-4/4S is always working with multiples of 8 DIMMs with the same capacity this issue won’t happen.
