Troubleshooting PCI-X Hot-Pluggable Operations
Sometimes a PCI-X card does not come online during a hot-pluggable operation due to a frequency
mismatch between the PCI-X card and the slot bus or due to other hardware errors. To determine
the type of error you are experiencing, observe the LED activity as described below. For a full
understanding and description of HP-UX 11i v2 hardware errors, read Interface Card OL* Support
for HP-UX Servers and Workstations, Important Considerations at http://hp.com.
1. PCI-X Bus Mode or Frequency Mismatch
After you insert a PCI-X card into the slot and push the attention button, the power LED
goes from blinking to steady-off and stays at steady-off; this means that the server firmware
has rejected the PCI-X card, and indicates either bus frequency or bus mode mismatch.
NOTE: After pushing the attention button, ensure that you wait the full five-second
operation cancellation window before taking further action.
2. Hardware Operation Fault
If the PCI-X card cannot be powered on during a hot-pluggable addition operation, the
attention LED turns steady-on and the power LED turns steady-off.
CAUTION: If your card does not power up, the power loss may be due to the existing
PCI-X expansion cards using all the available power. Check the power ratings of your existing
PCI-X cards. A known cause of power loss is the use of more than three RAID cards in your
server.
If the PCI-X card cannot be powered off during a hot-pluggable removal operation, the
attention button turns steady-on and the power LED remains steady-on.
CAUTION: If your slot does not power off during a hot-pluggable removal operation, do
not open the manual retention latch (MRL) on the OLX divider. This action may cause a
server failure or an operating system crash.
