The (ZFS) ARC Allocates Memory Inside The Kernel
Cage Preventing DR (6522017)
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 SunFire
TM
servers 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_arc_max = 0x20000000
mpathadm Does Not Display Load-Balance Setting
Specic to Device
The mpathadm show logical-unit subcommand lists the load balancing global conguration
value for the Current Load Balance property. However, entries in the csi_vhci.conf that
change the load-balance type for a specic product are not reected in the mpathadm output
even when the setting is active.
Registration Tool Prevents Power Management on
Some Framebuers (6321362)
If the background processes for the registration tool are left running, the Elite3D and
Creator3D framebuers stop power management. This failure reduces the power savings when
the system is in a power-managed state. Under certain conditions, sys-suspend might also hang.
No error message is displayed. The system might hang during a system suspend or resume
operation.
Workaround:
Run the following command approximately 60 seconds after each login:
# pkill -f basicreg.jar
# pkill -f swupna.jar
