Hi all, [Topic] Handling of invalid requests in virtual HBAs [Abstract] This discussion will focus on the problem of correct request handling with virtual HBAs. For KVM I have implemented a 'megasas' HBA emulation which serves as a backend for the megaraid_sas linux driver. It is now possible to connect several disks from different (physical) HBAs to that HBA emulation, each having different logical capabilities wrt transfersize, sgl size, sgl length etc. The goal of this discussion is how to determine the 'best' capability setting for the virtual HBA and how to handle hotplug scenarios, where a disk might be plugged in which has incompatible settings from the one the virtual HBA is using currently.
