38093 SCSI reservations should not be
blocked by the system manager
configuration lock.
Some long-running system operations such as
dynamic optimizations for large volumes could
occasionally result in SCSI-2 reservations not
being handled in a timely manner, and VMware
ESX hosts seeing high IO latencies.
This has been fixed by handling SCSI-2
reservations more efficiently even while the
system is busy with long-running operations.
38370 The CIM Server can hang if a client
sends a request after incompletely
processing the previous request.
If the CIM Server received a request from a
client and the client specifies in the HTTP
header that it supports chunked responses; if
the response for the request was large, the CIM
Server would send the response in chunks. If
the client sent another request without having
first completed processing of all of the pieces
of the first request, this could cause the CIM
Server to hang, waiting to send the rest of the
response to the first request to the client.
38848 A virtual copy from a mostly empty
Read-Write snapshot with a TPVV
base volume can be very slow.
When copying a Read-Write snapshot with a
TPVV base volume, only parts of volume that
has been written to needs to be copied. The
code that reads metadata to search for offsets
that have been written becomes very
inefficient if the Read-Write snap is mostly
never written to.
The algorithm has been fixed to properly
handle this case.
39666 Incorrect termination of some SCSI
control commands during a Fibre
Channel port reset causes the
controller node to restart.
When a Fibre Channel adapter port was reset,
the controller node could sometimes go offline
due to a validity check failing due to certain
host SCSI commands, such as Test Unit Ready,
being incorrectly marked as completed prior to
the status being returned to the host.
