51285 A large WRITE SAME command can
cause uncontrolled shutdown of a
controller node.
Handling of a WRITE SAME command
with a size of 32MB or larger had a
defect that could cause an
uncontrolled shutdown of a controller
node.
The code path has been fixed to
handle a large
WRITE SAME command
properly.
51523 Functions checkld and ldck
broken for Raid 5 (R5) logical disks
(LDs) larger than 1TB.
Corrected signed/unsigned 32 bit
overflow problem so that R5 LDs are
now correctly checked regardless of
size.
51553 Corrupted or invalid data in an FC
SCSI reservation frame may cause a
node to panic.
A SCSI reservation message containing
an invalid or corrupted data length
field caused the InServ to panic.
Boundary checks have been added to
prevent this from occurring.
51589 Remote Copy over Fibre Channel
(FC) can cause an uncontrolled node
shutdown if the attached FC fabric
is causing the links to bounce up
and down.
If the Remote Copy over FC link is
repeatedly dropping and reconnecting
the system can enter a deadlock
scenario whereby the link is
attempting to connect a link which is
attempting to shutdown. This issue is
fixed.
51593 When freeing snapshot data space,
controller node can fail a meta data
clean check.
When freeing snapshot data space,
the InForm OS did not wait for meta
data to be fully committed on all
nodes in the system which caused the
meta data clean check to fail.
The fix is to properly commit all meta
data before doing the clean check.
