6.7.6.4 fru
The fru command is similar to the SRM show fru command. It is used to access information in
the shared RAM FRU EEROM locations based on the logical device name you enter at the
dev> prompt. The logical device names are:
Name Meaning
cpu0, cpu1, cpu2, cpu3 CPUs
dimm {0-31} Memory DIMMs
mmb {0, 1, 2, 3} Memory motherboards
sys System board
pci PCI backplane
The following example shows information on the CPU0 module.

6.8 Option Card Problems
Option card problems can include problems related to network options and PCI options.
Network Problems
Network problems can vary, depending on the type of network option card that you have
installed. See the option card documentation for information on troubleshooting network
problems. Make sure you have correctly set the network type for the network interface card.
PCI Parity Errors
Some PCI devices do not implement PCI parity, and some have a parity-generating scheme that
may not comply with the PCI Specification. In such cases, the device functions properly as
long as parity is not checked.
You can turn off parity checking so that false PCI parity errors do not result in machine check
errors. When you disable PCI parity, no parity checking is implemented for any PCI device.
For Tru64 UNIX and OpenVMS systems, use the set pci_parity off command from the SRM
console.
