Workaround 2: If you reboot the system before updating the path_to_inst le and the /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. Once the system is back on, follow steps 2 and 3 in Workaround 1.

4. Power o the system.

5. Reinstall the HCA.

6. Reboot the system.

If the system reboots but the ibd interfaces do not automatically plumb, you might have to

manually rename the /etc/hostname.ib<?> les to reect the current device conguration.

The ZFS ARC Allocates Memory Inside the Kernel Cage

Preventing DR (15377173)

ZFS can potentially allocate kernel memory across all system boards on systems with very large

memory congurations. One free system board is required for dynamic memory

reconguration so that the memory from the board to be dynamically recongured can be

copied to the free board. The dynamic memory reconguration means that you cannot

dynamically recongure memory on systems with very large memory congurations that have

ZFS running. High-end Sun Fire servers from Oracle can relocate kernel pages so that this issue

is avoided. These servers must have kernel page relocation (KPR) enabled for domains with

more than 32 cores. No error message is displayed

Workaround: Reduce the amount of kernel memory that ZFS can allocate by setting the

zfs_arc_max parameter in the /etc/system le. The following example sets the maximum size

to 512 Mbytes.

set zfs:zfs_arc_max = 0x20000000

Certain USB 2.0 Controllers Are Disabled

Support for certain USB 2.0 controllers has been disabled because of incompatibilities between

these devices and the EHCI driver. The following message is displayed:

Due to recently discovered incompatibilities with this

USB controller, USB2.x transfer support has been disabled.

This device will continue to function as a USB1.x controller.

If you are interested in enabling USB2.x support please refer
