writing, the MegaRAID Storage Manager and the WebBIOS in current
ServeRAID firmware are limited to address 16 adapters only.
To configure all 32 adapters you may remove the first sixteen adapters, configure
the remaining installed adapters, and then reinsert the adapters you removed
and configure them. Or, you may use the LSI MegaCli command line utility, which
does not have this limitation. This limitation should be fixed in future controller
firmware and MSM.
