Get Serial Number from scsi harddisk.
Hello Everybody
Does anybody know if I can read the ID of a scsi harddisk?
Reading the ID of IDE disks like discribed in http://dev-archive.earthweb.com/system/DiskId32.shtml works fine, but my software is going to run on servers which normally have scsi drives working in raid mode.
I think on scsi drives a serial number is implemented much longer than on IDE drives, but I have not yet found out how to get it.
Can anybody help, please?!

Why, does the error occur in the DeviceIoControl function?
#define FILE_DEVICE_SCSI 0x0000001b
#define IOCTL_SCSI_MINIPORT_IDENTIFY ((FILE_DEVICE_SCSI << 16) + 0x0501)
