• Fixed a metadata map creation issue which could lead to a recursive termination (termination code 0x0442011f). • Fixed a controller termination (termination code 0x070b0100) that occurred when attaching to an empty container that is part of a disk group under reconstruction. • Fixed an issue which caused a controller termination (termination code 0x0442011f) when a bad block reassign was sent to a disk drive with a failed port. Disks (disk groups, virtual disks) This section describes issues affecting physical and virtual disks or disk groups, which can lead to a range of behaviors including a loss of redundancy, performance impact, or data unavailability. • Resolved an issue that resulted in a false metadata inoperative condition (Operator Control Panel message System Inoperative displayed) due to multiple missing drives. • Improved diagnostic capability in rare instances of an incomplete storage cell metadata update (termination code 0x0442011F). • Added diagnostic capability in rare instances of an unexpected metadata field change (termination code 0x03020184). • Added diagnostic capability to obtain more information about background redundant operations being completed prematurely or indicated as completed prematurely (termination code 0x0442011F). • Enhanced disk group leveling to ensure all background redundant structures are equal (level). • Enhanced virtual disk expansion process to ensure allocation has completed before reporting the new capacity. • Fixed an issue in which the array was declared inoperative due to a misdiagnosed metadata state. • Fixed an issue during disk drive regeneration/ungrouping that could result in allocation that violates RAID selection criteria. • Fixed an issue where erroneous reporting of misconfigured backend devices (event 0x031f9923) was occurring. • Addressed an issue where excessive reporting of unrecovered read medium errors from a disk drive led to a Unit Stalled Too Long event (event 0x4206001b). Hardware (replaceable parts, device ports, resynchronization) This section describes issues affecting physical hardware, which can lead to incorrect condition handling, false condition reporting and similar events that may lead to incorrect device status reporting or replacement. • Added a verification step to ensure that an accurate cache battery state is returned for HSV300 controllers to avoid falsely triggered cache policy changes. • Added functionality to put cache in the Write Through state when the controller critical temperature threshold is exceeded. • Fixed an issue caused by congestion within the Fibre Channel fabric, which led to controller host port freezing and lost connectivity. • Fixed an issue that caused the reporting of false critical events even though the blower was operating normally. • Fixed an issue which caused all disks within an enclosure to be bypassed by the midplane firmware when the enclosure was powered on.

•
Fixed a metadata map creation issue which could lead to a recursive termination (termination
code
0x0442011f
).
•
Fixed a controller termination (termination code
0x070b0100
) that occurred when attaching to
an empty container that is part of a disk group under reconstruction.
•
Fixed an issue which caused a controller termination (termination code
0x0442011f
) when a
bad block reassign was sent to a disk drive with a failed port.
Disks (disk groups, virtual disks)
This section describes issues affecting physical and virtual disks or disk groups, which can lead to a
range of behaviors including a loss of redundancy, performance impact, or data unavailability.
•
Resolved an issue that resulted in a false metadata inoperative condition (Operator Control Panel
message
System Inoperative
displayed) due to multiple missing drives.
•
Improved diagnostic capability in rare instances of an incomplete storage cell metadata update
(termination code
0x0442011F
).
•
Added diagnostic capability in rare instances of an unexpected metadata field change (termination
code
0x03020184
).
•
Added diagnostic capability to obtain more information about background redundant operations
being completed prematurely or indicated as completed prematurely (termination code
0x0442011F
).
•
Enhanced disk group leveling to ensure all background redundant structures are equal (level).
•
Enhanced virtual disk expansion process to ensure allocation has completed before reporting the
new capacity.
•
Fixed an issue in which the array was declared inoperative due to a misdiagnosed metadata
state.
•
Fixed an issue during disk drive regeneration/ungrouping that could result in allocation that violates
RAID selection criteria.
•
Fixed an issue where erroneous reporting of misconfigured backend devices (event
0x031f9923
)
was occurring.
•
Addressed an issue where excessive reporting of unrecovered read medium errors from a disk
drive led to a Unit Stalled Too Long event (event
0x4206001b
).
Hardware (replaceable parts, device ports, resynchronization)
This section describes issues affecting physical hardware, which can lead to incorrect condition
handling, false condition reporting and similar events that may lead to incorrect device status reporting
or replacement.
•
Added a verification step to ensure that an accurate cache battery state is returned for HSV300
controllers to avoid falsely triggered cache policy changes.
•
Added functionality to put cache in the Write Through state when the controller critical temperature
threshold is exceeded.
•
Fixed an issue caused by congestion within the Fibre Channel fabric, which led to controller host
port freezing and lost connectivity.
•
Fixed an issue that caused the reporting of false critical events even though the blower was oper-
ating normally.
•
Fixed an issue which caused all disks within an enclosure to be bypassed by the midplane firmware
when the enclosure was powered on.
