Memory
The main memory for an HP V ISUALIZE B1000/C3000 workstation can vary from a
minimum of 128 MBytes to a maximum of 2 GBytes. The workstation has eight memory
card slots. Currently the B1000/C3000 workstations support only 128 MByte and 256
MByte memory DIMM cards in these slots.
To install DIMM cards in the B1000/C3000 workstation reference “Installing Additional
Memory” on page 141 in this Service Handbook.
CAUTION If memory is installed improperly or it is defective the B1000/C3000
workstation operating system will not boot-up, and a DIMM error will appear
in the LCD. If an error does occur, reference Chapter 3, “Troubleshooting” for
additional information.
Memory Failures
The HP V ISUALIZE B1000/C3000 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 command memrpt with the detail switch to obtain information about the
Memory Page Deallocation Table (PDT) as well as single bit errors logged by the system.
# /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
pdt clear command to clear out the PDT.
