Product Information
Memory
Memory
The B2000 workstation has four slots for memory DIMMs. You can install only 128 MB,
256 MB, or 512 MB DIMMs in these slots. The minimum memory configuration for a
B2000 workstation is 256 MB, and the maximum is 2 GB.
To install memory DIMMs, refer to “Replacing or Installing Additional Memory DIMMs”
on page 115.
CAUTION
If memory is installed improperly or is defective, the B2000 workstation’s
operating system will not boot-up, and a DIMM error chassis code will appear
in the LCD. If an error does occur, refer to Chapter 3, “Troubleshooting.”
Memory Failures
The HP V
ISUALIZE
B2000 system (with HP-UX 10.20 and later) uses Memory Page
Deallocation, a feature that allows the system to provide information to the operating
system about memory failures.
You can use the
memrpt
command with the
detail
switch to obtain information about the
Memory Page Deallocation Table (PDT) as well as single bit errors logged by the system,
by typing the following:
# /usr/sbin/sysdiag
Enter
DUI>logtool
Enter
LOGTOOL>memrpt detail
Enter
The PDT can also be checked using the
pdt
command in the Service menu of the Boot
Console Handler (refer to Chapter 6). If you replace a defective DIMM, use the Service
Menu’s
pdt clear
command to clear out the PDT.
