Superdome qualified memory


Hi All,
I am investigating a problem where an rp7410 was upgraded with additional memory , using 4 x 1gb quads A6908-60101.

The engineer had problems getting the memory recognised and noted that whilst BHP saw the new memory, it was deconfigured.

Other reasons apart, I note that there is a fix in firmware update v5.0 PDC 16.011 that states that a fix for PDC not recognising 'superdome qualified memory' .

Whats that then ? I note that the memory part number used is a latest sub for the rp7410 and also stated as a memory part for Superdomes.

We know the rp7410 is likley to be at a lower firmware level than 5.0, and expect to recommend an upgrade, but just wondering how justified this is based on the patch fix above.

I am well aware that there may be other causes of the problem, but info other than the above, which might well show a basic install issue has not yet come my way.

Thanks, Geoff

Hi Geoff

Please check whether following memory configuration rule is followed for rp7410 server

When purchased from the factory, any given partition can be ordered with 4 GB Dimms or non-stacked Dimms (512 MB, 1GB or 2GB), but not both. When field integrated, cell boards can contain 4GB Dimms or non-stacked Dimms (MB, 1GB or 2GB), but not both.

Thanks Mahesh,

They are non stacked dimms of either 512 or 1gb.
To get the upgrade one cell (partition) is upgraded from 4gb , 2gb , 2gb, 2gb quads to 4gb, 4gb, 2gb, 2gb and the other cell (partition) from 2gb, 2gb, 2gb, 0gb to 4gb, 4gb,4gb,2gb,2gb quads.

With HP support, confirmed that later memory had been written for superdomes, and that there is indeed a firmware update required for this memory.

However we also obtained a third batch of memory, tested, and installed without problem.
