Memory interleaving is left in an incorrect state when a Sun Enterprise x500 server is rebooted after 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 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 (BugID 4210234).
