52915 Need to create /dev/tpddev
devices asynchronously.
On large system, the System Manager
controller node initialization process
to deliver the physical disk, logical
disk, and virtual volume information
into the kernel was taking too long.
This was due to the creation of Linux
device entries for each of these
devices.
The System Manager controller node
initialization process was used only for
internal system access. The process
was pushed to a background thread
removing this problem.
53020 Canceled inter-cluster message can
cause memory corruption.
Due to a defect in InForm OS that does
not handle canceled messages
properly, memory can be overwritten
after it is returned to free pool which
causes memory errors. A fix has been
implemented to free up memory only
after it is no longer needed.
53046 Controller node down on Raid 6
(R6) chunklet move with specific
CRC and other error case.
Correct a possible controller node
down problem in the R6 CRC
regenerate and re-write processing
when this action occurs as part of a R6
chunklet relocation.
53087 Node reboot error. Issues were found with the LP
congestion algorithm being used in
2.3.1. However, for 2.3.1 MU2 3PAR
moved away from using LP for the
congestion algorithm to the BIC
congestion algorithm. Issues with LP
congestion algorithms will not be seen
with 2.3.1 MU2.
