▼ Temporarily Disable All Memory Modules
A disabled CMP node complicates the memory topology and can prevent a system
from booting. To run the system in a degraded state, you must reduce the total
amount of system memory by disabling all of the FB-DIMMs on all of the memory
modules in order to work around this complication.
If you are recovering from a failed CMP module, you must temporarily disable the
FB-DIMMS on all memory modules when Solaris is halted and the system is
powered off. The FB-DIMMs are re-enabled after the I/O and PCIe devices are
reconfigured.
You can either physically remove the memory modules from the system, or remotely
disable all FB-DIMMs located on all memory modules using the
disablecomponent
command.
To remove the memory modules from the system, see the instructions in the SPARC
Enterprise T5440 Server Service Manual.
To remotely disable all FB-DIMMs in the system, do the following:
1. Halt the Solaris OS.
2. Power off the system.
# halt
