The VRTX enclosure
enables the fail-safe mode to protect the server modules and the I/O
module from failures. The fail-safe mode is enabled when no CMC is
in control of the chassis. During the CMC failover period or during
a single CMC management loss:
server modules cannot be accessed remotely
you cannot turn on a server module(s)
the cooling fans continue to operate at the same
speed
The following are some of the conditions that
can result in CMC management loss:
Condition
Description
CMC removal
Chassis management resumes after replacing CMC, or
after failover to standby CMC.
CMC network cable removal or network connection loss
Chassis management resumes after the chassis fails
over to the standby CMC. Network failover is only enabled in redundant
CMC mode.
CMC reset
Chassis management resumes after the CMC reboots
or chassis fails over to the standby CMC.
CMC failover command issued
Chassis management resumes after the chassis fails
over to the standby CMC.
CMC firmware update
Chassis management resumes after the CMC reboots or
chassis fails over to the standby CMC. It is recommended that you
update the standby CMC first so that there is only one failover event.
For more information about updating the CMC firmware, see the Dell
Chassis Management Controller for Dell PowerEdge VRTX User’s Guide at Dell.com/esmmanuals.
CMC error detection and correction
Chassis management resumes after the CMC resets or
chassis fails over to the standby CMC.
NOTE: You can
configure the enclosure with a single CMC or with redundant CMCs.
In redundant CMC configurations, if the primary CMC loses communication
with the enclosure or the management network, the standby CMC takes
over chassis management.
