Hannes, I have been contemplating this for a bit. >> Has it been considered instead of introducing a blacklist flag to not >> use the reported VPD page size if the device reports that the VPD >> page size is zero? I am not aware of any VPD pages for which zero is >> a valid size. That would also be my preferred approach, I think. I haven't received any bug reports about devices returning short VPD pages since this change was introduced. So I think I'd prefer falling back to a (hopefully small) default if a device returns a 0 page length. Now, my question is which VPD pages are actually supported by this device and how large are they? > But pre-SPC drives will ignore the VPD bit in the inquiry size. And > these devices do not set an additional length in the inquiry data Can you elaborate a bit on your experience with older devices? I checked SCSI-2 (1991) and don't see any indication this would be valid behavior even back then. -- Martin K. Petersen Oracle Linux Engineering
