Installation guide

c. Search for lines that contain ibd and hermon, and delete those lines.
d. Save the changes and close the le.
3. Remove the entries in the /dev directory:
rm /dev/ibd?*
4. Reboot the system. The system boots normally, and the corresponding device tree looks like
this:
# ls -R /devices | grep 15b3
/devices/pci@0,0/pci10de,5d@e/pci15b3,5@0
/devices/pci@0,0/pci10de,5d@e/pci15b3,5@0/ibport@1,ffff,ipib
/devices/pci@0,0/pci10de,5d@e/pci15b3,5@0/ibport@1,ffff,ipib:ibd0
/devices/pci@0,0/pci10de,5d@e/pci15b3,5@0/ibport@2,ffff,ipib
/devices/pci@0,0/pci10de,5d@e/pci15b3,5@0/ibport@2,ffff,ipib:ibd1
/devices/pci@0,0/pci10de,5d@e/pci15b3,5@0:devctl
Workaround 2: If you reboot the system before updating the path_to_inst le and /dev
directory, the system might hang. In such a case, perform the following steps:
1. Power o the system and remove the HCA from the bus.
2. Reboot the system without the HCA installed.
3. When system is back on, follow steps 2 through 3 listed in Workaround 1.
4. Power o the system.
5. Re-intsall the HCA. Reboot the system.
6. If the system reboots, but ibd interfaces do not automatically plumb, the
/etc/hostname.ib<?> les might not be appropriate for the current device conguration.
Manually rename the les to reect the correct conguration.
Unrecoverable Machine-Check Exception on PCIe
(6797934)
Some IBM systems either hang or panic after install. The following panic message is displayed:
Unrecoverable Machine-Check Exception
Workaround 1: Add the following line to the /etc/system le after installation to avoid system
hang:
set pcie:pcie_aer_ce_mask=0x11C1
Workaround 2: If the system panics during install or during boot after the install, then use this
workaround. Boot the system, with -kd option and set it in the kmdb debugger:
