5. For a 7026 or a 7040 with a SP Switch2 PCI adapter, do the following:
Efence -p x nn
(where x is plane number 0 or 1 and nn is the node_number of the server or logical partition)
RESPONSE: All nodes successfully fenced.
6. On the object server or logical partition (or with the dsh command), type:
/usr/lpp/ssp/css/ifconfig css0 down detach
Note: In a dual-plane environment, this could be performed on css0, css1 or both.
RESPONSE: driver unconfig OK
RESPONSE: driver unloaded
7. On the object server or logical partition (or with the dsh command), type:
stopsrc -s hats
RESPONSE: 0513-044 The hats subsystem was requested to stop
8.

to the adapter.
12. Run the following commands to remove power to the slot into which the adapter is plugged. This
action is necessary to activate the Xilinx update.
echo | /usr/sbin/drslot -R -c pci -l css0 -I
* echo | /usr/sbin/drslot -R -c pci -l css1 -I
If the previous command is run using dsh from the CWS, quotation marks are required around the
entire command as follows:
dsh "echo | /usr/sbin/drslot -R -c pci -l css0 -I"
13. Reboot the server or logical partition. Type:
shutdown -Fr
14. When the server or logical partition is back up, from the CWS, type:
