Solaris

Hello,

I have a HP ProLiant DL385 ( X86 ) running Solaris 10 on it.

Our hardware team passwd by server last night and noticed an amber light to indicate a possible bad dimm.

/var/adm/messages, dmesg, prtdiag -v, all shows nothing.

/opt/HPQhealth/sbin/hpasmcli indicated I have a bad dimm at module 2:

Cartridge #: 0
Module #: 2
Present: Yes
Form Factor: 9h
Memory Type: 12h
Size: 2048 MB
Speed: 400 MHz
Status: Dimm is degraded

Since this server has 8 memory and 2 CPUs, customer is requesting to isolate this bad dimm and keep the server running for production applications.

System Configuration: HP ProLiant DL385 G1
BIOS Configuration: HP A05 03/01/2006

DDR in use 2 DIMM 04

Does anyone know how to isolate DIMM 02 online by either Solaris 10 command or HP command?

Thank you very much,

SC

what do you mean with "isolate"?

Hello,

What I meant is to "isolate" the bad dimm from OS Level, so the OS will not see/use this bad dimm and continue to run with 7 other good dimm ( without bringing system down ).

i don't think this is possible in a x86 system... the only command comming to my mind for dynamic reconfiguration is cfgadm.

Thank you very much. Yeah, when I was running "cfgadm -al", I can't even see memory info like what usually will shows up on a SPARC host.

Seems like HP has there own tool called "ProLiant Memory Configuration Tool", which I don't have on my server either for configuration.

Thank you very much.

Even if a command allows disabling that dimm, that would be impossible to run with 7 of them.
Six would be the best option as they must be installed in pairs.
