I was wondering if there is any mechanism to re-scan specific HBA port from user space with IOCTL/API ? This is required for our user space implementation to issue HBA re-scan instead of whole storage stack refresh.
I had come across this IOCTL : IOCTL_SCSI_RESCAN_BUS IOCTL which is directed towards non-PNP drivers and it says as obsolete.
Apart from this In powershell, i figured out there is "Get-InitiatorPort" module which does list of all HBA/SCSI port's in system and Update-HostStorageCache (Diskpar | rescan) which does all volume/storage objects refresh. But, I found none of the user space API/component which can issue rescan on specific HBA. i.e. All driven by PnP mechanism only.
Am i missing something here ? Could someone help on this please.
