Interface Card OL* Support Guide

OL* Action Behavior Issue
If an online replace or an online delete operation is performed on the PCI-E x8 switched slots,
the slot becomes unusable under the following conditions:
• Operating System: HP-UX 11i v3
• HP Integrity servers: rx3600 or rx6600 with express I/O backplane
• Firmware Version: 2.03
During online replace operation through olrad command, pdweb tool, or Attention button, the
card in the PCI-E x8 switched slot (slot 3 or slot 4) becomes unusable. The ioscan(1M) command
displays the driver state for the card in that slot as SUSPENDED.
During online delete operation through olrad command, or pdweb tool, the card in the PCI-E
x8 switched slot (slot 3 or slot 4) becomes unusable. The ioscan(1M) command displays the driver
state for the card in that slot as UNUSABLE.
Cause:
OL* operations are not supported on PCI-E x8 switched slots (slot 3 and 4 on rx3600 / rx6600
with express backplane) with firmware revision 2.03 and these slots are not displayed in the -q
option of the olrad(1M) command. But due to a defect in the HP-UX OL* infrastructure subsystem,
olrad command is incorrectly allowing operations like online replace and online delete to be
performed on these slots, resulting in the above behaviour.
Workaround:
If you reboot the system, you can recover the slot, and the card in the recovered slot will be usable
again.
NOTE: To verify the firmware version, you can use the STM command or sysrev command
from the Management Processor (MP) Command Menu (CM) prompt as follows:
MP: CM> sysrev
