HP 3PAR OS 3.1.2 MU5 Release Notes

coherent and let the battery charge level to set to normal. On releases
before 2.3.1.MU5, there's no workaround that would fix the problem
without interrupting system. On such system, the only way to get the
system to work normally is to restart sysmgr.
If we have a heavily loaded system and have snapshots with lots of
data, the meta data tables of which are heavily populated, then on
Deleting a very large and filled
snapshot can lock up a CPU for a
long time

deleting some of these snapshots the meta data tables are traversed
causing the cpu on occasions to be held for an excessive amount of
time. This can cause the locking out other processes/tasks from running
and can cause the background internode comms processing to be
delayed resulting in the erroneous belief that one of the other nodes
has died. This fix prevents the cpu from being held for an excessive
amount of time while traversing the meta data tables during snapshot
removal. This fix includes an enhancement to cover off the case where
the meta data tables are being merged during snapshot removal. This
enhancement fix is applied to 2.3.1.MU5, 3.1.1.MU1, and 3.1.2.
The firmware has a bug where it trashes its internal copy of scatter
gather list which results in the fw trying to access invalid/incorrect
Core dumps65663
addresses. This bug can be triggered only when fw is requiring to
use DDR memory for BLP storage. If DDR memory was used at any
time in the past, there is a potential of the fw polluting its internal
memory (and thus using invalid/incorrect host memory addresses) till
the port has been reset.

Four new commands have been added to allow the creation, update,
removal and display of Adaptive Optimization configurations via the
CLI. These new commands are:
Move AO configuration into the TOC65800
• createaocfg - create a new AO configuration
• setaocgg - modify an AO configuration
• removeaocfg - remove an AO configuration
• showaocfg - show AO configurations
See the individual commands for usage & licensing information.
Fibre Channel (FC) target ports will register new node and port
symbolic information starting in 3.1.2.
node/port symbolic information65906
Node symbolic information is of the form:
Legacy systems: HP_3PAR 7000 <model>-<serial>-fw:<release>
7200 systems: HP_3PAR 7200 - <serial>-fw:<release>
7400 systems: HP_3PAR 7400 - <serial>-fw:<release>
where <model> is the legacy system model, such as V800; <serial>
is the system serial number, e.g., 1499607; and <release> is a four
digit number representing the HP 3PAR OS release and MU, e.g.,
3120 for 3.1.2 GA, 3121 for 3.1.2 MU1.
Port symbolic information is of the form:
<serial> - <n:s:p> — <type>
where <serial> is the system serial number, e.g., 1499607; <n:s:p>
is the location of the port, e.g., 1:3:2; and <type> is the type of the
HBA, eg., LPe12004.
Node and port symbolic information are registered with the FC fabric.
On Brocade switches, nsshow will display this information. On Cisco
