adding memory to sun blade server ...
Hi, this is my 1st post here, I don't know is it proper or not for the question I have, but I may try ask anyway, since it is question about sun's hw/sw issue...
I have my blade 1000 installed additional memory kits, it was originally 2G memory installed on Group0(Bank 0/2) Dimm slots, I got some 2nd hand memory kits from eBay, and installed it, after reboot(touch /reconfigure, shutdown,then install memory modules), I use "prtconf -v" but something caught my eye, the " memory-controller, instance #1" is different as usual:
.....
memory-controller, instance #0
Driver properties:
name='logical-bank-ma-regs' type=int items=8 dev=none
value=80007e00.00030000.80007e00.00030100.80007e00.00030200.80007e00.00030300
Register Specifications:
Bus Type=0x400, Address=0x400000, Size=0x48
Device Minor Nodes:
dev=(158,0)
dev_path=/memory-controller@0,400000:mc-us3
spectype=chr type=minor
dev_link=/dev/mc/mc0
SUNW,UltraSPARC-III, instance #1
Driver properties:
name='pm-class' type=string items=1 dev=none
value='CPU'
name='pm-components' type=string items=4 dev=none
value='NAME=CPU Speed' + '1=1/32 of Normal' + '2=1/2 of Normal' + '3=Normal'
Register Specifications:
Bus Type=0x400, Address=0x800000, Size=0x10000
memory-controller, instance #1
Driver properties:
name='logical-bank-ma-regs' type=int items=8 dev=none
value=00000000.00000000.00000000.00000000.00000000.00000000.00000000.00000000
Register Specifications:
Bus Type=0x400, Address=0xc00000, Size=0x48
Device Minor Nodes:
dev=(158,1)
dev_path=/memory-controller@1,400000:mc-us3
spectype=chr type=minor
dev_link=/dev/mc/mc1
I'm wondering about why "memory-controller, instance #1" got all "0" value other then "memory-controller, instance #0"? it actually got total 4G memory now, but why the new installed 2G memory kits got all "0" value information? what does the "value=" mean in the section? anything I shall watch out especially?
my sun balde 1000 was installed solaris 10 8/07, with recommanded patch installed.
thanks.

NAME
dpt - DPT ServeRAID IV SCSI host bus adapter and RAID adapter driver
DESCRIPTION
The dpt driver is a driver for the DPT (Distributed Processing Technology) family of SmartRAID IV SCSI HBA and RAID adapters. The following
HBA adapters are supported: PM2024, PM2044UW, PM2044W, PM2124, PM2124W, PM2144UW, and PM2144W.
The following RAID adapters are supported: PM3224, PM3224W, PM3334UW, and PM3334W.
PRECONFIGURATION
o DPT PM3224 only: Only EPROM 7A and later versions are supported.
o DPT PM2024 and PM2124 only: Only EPROM 6D4 and later versions are supported.
o Use adapters with SmartROM version 3.B or later versions only.
o Be sure that the controller board is installed in a PCI bus-mastering slot.
o Disable PCI parity checking if your firmware version is earlier than version 7A, if your system memory is ECC, or if your system does
not check parity.
Known Problems and Limitations
During system boot, a message may be displayed saying a DPT controller driver cannot be installed. This message indicates that the mother-
board installed in your system may contain ECC memory or may not check parity. If you see this message is displayed, disable PCI parity
checking.
Supported Settings
o I/O Address: Auto
CONFIGURATION
Auto-configuration code determines whether the adapter is present at the configured address and what types of devices are attached to it.
The DPT ServeRAID is primarily used as a disk array (system drive) controller.
To configure the attached disk arrays, you must configure the controller (using the configuration utilities provided by the hardware manu-
facturer) before you boot the Solaris operating environment. You use the configuration utilities to set RAID levels, stripe parameters,
cache mechanisms and perform other functions. For more information, see the user manual supplied with your hardware.
