3PAR InForm Operating System Release Notes InForm OS Version 2.3.1
41341 Network controller process can
terminate when attempting to
switch the admin interface between
nodes.
Due to a timing issue netc can terminate when
it is in the process of switching the admin
interface between nodes.
41455 Command stuck in iSCSI driver with
the Cluster Memory Page (CMP)
locked resulted in failed to send
reply panic.
When an iSCSI connection is closed, the iSCSI
driver in the InServ Storage Server was not
correctly releasing the pending commands. This
could sometimes lead to a controller node
going offline when the command timed out.
This has been corrected by cleaning up all
pending commands when an iSCSI connection
is closed.
41992 On very large (many TB) snapshots,
allocating snapshot space can
become extremely slow that makes
nodes to be non-responsive.
The algorithm that searches for available space
in a snapshot does not scale well with size of
the snapshot.
The algorithm has been changed to deal with
very large snapshots.
41995 Incorrectly zoned RCFC
configuration results in memory
exhaustion and controller node
restart.
Under certain error conditions, the Remote
Copy over Fibre Channel transport software
was not releasing 8KB memory blocks leading
to the controller node going offline when it
ran out of available memory.
42161 Renaming a virtual volume during
an updatesnapspace operation
prevents virtual volume removal.
A renamevv command run while an
updatesnapspace command was active on that
virtual volume would prevent the virtual
volume from being removed later.
The correct flags are now updated.
