was integrated into the createsv command, using the -rcopy switch.

Upgraded 1G iSCSI firmware to version 3.0.1.67 in order to address
a firmware issue which could cause port resets due to mailbox
command timeouts under heavy I/O load.

If a 1G iSCSI port on the array comes up at a negotiated port rate
that is lower than the expected 1G rate, an alert is generated. The

showport -iscsi command now displays the actual rate; previous
releases used to display 1Gbps regardless of the actual rate the link
came up at.
This release fixes the controlport rate command to allow for a

of that data rate. Previously only the rate setting of 'auto', which is
the default, would achieve a 8Gps rate for those ports.
Misleading alerts indicating that a cage is inaccessible, are no longer
emitted at the time of System Manager startup.

Fixed a driver bug that could cause a link list break in a very rare
condition.

The updatevv -anyid option is deprecated. In 3.1.2 we changed
the volume and snapshot removal handling in System Manager. When
Deprecate updatevv's -anyid option69439
a volume or snapshot is removed, it is not cleaned up immediately.
It remains hidden until a background thread recycles the resource.
That means upon removal, the id of the volume is still being occupied,
so updatevv may fail. In 3.1.2, we are using a different volume id
but keep the same WWN when the snapshot is updated. Now
updatevv calls a modified creategroupsv command which will
always use the same WWN to create the new snapshot.
The XR3B firmware will lower a temperature threshold. The patch will
modify the firmware database to cause the required firmware on

Moose drives to be XR3B. SN: P90 will modify the scsidb to point the
current firmware for Moose to be XR3B. As this is a scripted
modification the scsidb it will need to be applied after every upgrade,
before admithw is run.
In cases where NL drives are overloaded in the extreme, upper layers
can see this as loss of access. If multiple NL drives are in this state,

this loss of access can result in volumes going into preserved state.
Along with other fixes to prevent this type of overloading (as in 77976)
we also now allow longer NL access times and ensure multiple retries
to ensure what looks like loss of access is actually so.
If a network message is sent to a node that then is removed from the
system, the networking infrastructure hangs. Any future network issue

cannot be handled, ultimately resulting in connectivity loss to the
cluster until the network interface is restarted. A fix was made so that
the network interface does not hang in this situation but eventually
times out instead, allowing handling of other networking changes.

efficiently in HP 3PAR OS 3.1.2. This can lead to improved
