Causes for INCOMPATIBLE status
When an interconnect module status is INCOMPATIBLE, details can be viewed in the System log ("System
Log (System Log) screen" on page 39). The system log provides information about why an interconnect
module is marked incompatible so that proper corrective action can be taken.
The following list provides reasons why an interconnect module might be INCOMPATIBLE and the suggested
corrective actions:
• Module adjacency
Typically, interconnect modules installed in adjacent bays must be of the same type. For more
information, see the installation guidelines in the HP Virtual Connect for c-Class BladeSystem Setup and
Installation Guide on the Installing tab of the HP BladeSystem Technical Resources website
(http://www.hp.com/go/bladesystem/documentation).
If two adjacent modules are incompatible, both modules are labeled as INCOMPATIBLE, since the rule
applies to both modules.
Corrective action: Remove the adjacent incompatible modules and replace with modules that are
compatible.
• Module replacement
If an interconnect module is being used by the domain and is physically removed, and then another
module is installed in the same bay, the new module must be the same type as the module previously
installed in the bay.
If the physically removed module was not being used by the domain, the module can be replaced with
a module of a different type.
VC-Enet modules are considered in use by the domain under the following conditions:
o Uplinks or downlinks are being used by networks/profiles.
o The module is the primary or standby module.
VC-FC Modules are considered in use by the domain under the following conditions:
o Uplink ports on the module are being used by a fabric.
o The fabric is being used by a profile connection.
Corrective action: Remove the incompatible module and replace with the previously existing module.
For more information, see "Interconnect module removal and replacement (on page 204)."
• Firmware version
Only modules with firmware versions supported by the firmware running on the primary module are
compatible. All other versions of firmware modules cause the module to be marked as INCOMPATIBLE.
Corrective action: Use VCSU to update incompatible modules to the appropriate firmware versions for
the domain. For more information on updating the firmware, see the HP BladeSystem c-Class Virtual
Connect Support Utility documentation on the Installing tab of the HP BladeSystem Technical Resources
website (http://www.hp.com/go/bladesystem/documentation).
• FC bay groups
In a multi-enclosure environment, all enclosures must have the same FC module configuration. For more
information, see "Multiple enclosure guidelines (on page 49)."
Corrective action: Remove the incompatible module and replace it with the correct module for the
existing FC bay group.
In a c3000 enclosure, VC-FC modules are not supported in bay 2.
