Memory Interleaving Set Incorrectly After a Fatal Reset, Bug-ID 4156075

Category: Bug

Memory interleaving is left in an incorrect state after a Sun Enterprise x500 server encounters a Fatal Reset. Subsequent DR operations fail. The problem only occurs on systems with memory interleaving set to min.

Workarounds: Two choices are listed below.

• To clear the problem after it occurs, manually reset the system at the OK prompt.

• To avoid the problem before it occurs, set the NVRAM memory-interleave property to max. This causes memory to be interleaved whenever the system is booted. However, you may find this option to be unacceptable, as a memory board containing interleaved memory cannot be dynamically unconfigured. See "DR: Cannot Unconfigure a CPU/Memory Board That Has Interleaved Memory, Bug ID 4210234".
