Event Messages and Error Messages
The following table lists MegaRAID Storage Manager event messages that might appear in the MSM event log when
the Syncro CS system is running.
Table 4 HA-DAS MSM Events and Messages
Number
Severity
Level
Event Text Cause Resolution
0x01cc Information Peer controller entered HA
Domain
A compatible peer controller entered
the HA domain.
None - Informational
0x01cd Information Peer controller exited HA
Domain
A peer controller is not detected or
has left the HA domain.
Planned conditions such as a system restart
due to scheduled node maintenance are
normal. Unplanned conditions must be further
investigated to resolve.
0x01ce Information Peer controller now manages
PD: <PD identifier>
A PD is now managed by the peer
controller.
None - Informational
0x01cf Information Controller ID: <Controller
identifier> now manages PD:
<PD identifier>
A PD is now managed by the
controller.
None - Informational
0x01d0 Information Peer controller now manages
VD: <VD identifier>
A VD is now managed by the peer
controller.
None - Informational
0x01d1 Information Controller ID: <Controller
identifier> now manages VD:
<VD identifier>
A VD is now managed by the
controller.
None - Informational
0x01d2 Critical Target ID conflict detected.
VD: <VD identifier> access is
restricted from Peer controller
Multiple VD target IDs are in conflict
due to scenarios that might occur
when the HA domain has a missing
cross-link that establishes direct
controller-to-controller
communication (called split-brain
condition).
The Peer controller cannot access VDs with
conflicting IDs. To resolve, re-establish the
controller-to-controller communication path
to both controllers and perform a reset of one
system.
0x01d3 Information Shared access set for VD: <VD
identifier>
A VD access policy is set to Shared. None - Informational
0x01d4 Information Exclusive access set for VD:
<VD identifier>
A VD access policy is set to Exclusive. None - Informational
0x01d5 Warning VD: <VD identifier> is
incompatible in the HA
domain
The controller or peer controller does
not support the VD type.
Attempts to create a VD that is not supported
by the peer controller result in a creation
failure. To resolve, create a VD that aligns with
the peer controller VD support level.
Attempts to introduce an unsupported VD
that is managed by the peer controller result
in rejection of the VD by the controller. To
resolve, convert the unsupported VD to one
that is supported by both controllers, or
migrate the data to a VD that is supported by
both controllers.
0x01d6 Warning Peer controller settings are
incompatible
An incompatible peer controller
parameter is detected. The peer
controller is rejected from entering
the HA domain.
The peer controller might have settings that
do not match the controller. These settings
can be corrected by a firmware update. To
resolve, update the firmware for the peer
controller and/or controller to ensure that they
are at the same version.
0x01d7 Warning Peer Controller hardware is
incompatible with HA Domain
ID: <Domain identifier>
An incompatible peer controller is
detected. The peer controller is
rejected from entering the HA
domain.
The peer controller hardware does not exactly
match the controller. To resolve, replace the
peer controller with a unit that matches the
controller hardware
