x64: PCI Subsystem ID Changes in ConnectX Firmware

2.6.0 From Mellanox (15544691)

Upgrading the ConnectX rmware to version 2.6.0 or higher on a running system might cause

problems in some HCAs and x64 platforms. This issue aects only Mellanox-branded HCAs.

Sun-branded PCIe HCAs, EMs, and NEMs, and SPARC platforms are not aected.

You might be unable to boot the system or the system might hang during boot. The ibd

(IPoverIB) instance numbers might change and prevent the system from booting and plumbing

ibd devices.

Choose one of the following workarounds.

Workaround 1: Before rebooting the system after updating the rmware using cxflash,

remove the ibdx instances from the /etc/path_to_inst le and the /dev directory. Perform

the following steps:

1. Log in as the root user and list the relevant devices.

The device tree information might look like the following example:

# ls -R /devices | grep 15b3

/devices/pci@0,0/pci10de,5d@e/pci15b3,634a@0

/devices/pci@0,0/pci10de,5d@e/pci15b3,634a@0/ibport@1,ffff,ipib

/devices/pci@0,0/pci10de,5d@e/pci15b3,634a@0/ibport@1,ffff,ipib:ibd0

/devices/pci@0,0/pci10de,5d@e/pci15b3,634a@0/ibport@2,ffff,ipib

/devices/pci@0,0/pci10de,5d@e/pci15b3,634a@0/ibport@2,ffff,ipib:ibd1

/devices/pci@0,0/pci10de,5d@e/pci15b3,634a@0:devctl

Note – Device specics vary depending on the Mellanox-branded card installed.

2. Edit the path_to_inst le.

a. Make a backup copy of the existing path_to_inst le.

# cp /etc/path_to_inst /etc/path_to_inst.backup

b. In the path_to_inst le, search for lines that contain ibd and hermon, and delete those

lines. Save 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
