No, scsi_rescan_device won't work of bringing a new device online or an old one offline. It's just when attributes on an existing device change. So to get this sorted out nicely we'd really need to know whether AifEnContainerChange means online/offline/clear. BTW, why/how does the hardware interact with partitioning on aacraid? And what's the exact meaning of AifDenMorphComplete? Is there some hardware documentation on adaptec's website?
