Hi,John
Is this the another problem ? Or triggered by this bug? If trigger by this bug,seem not fixed.
best regards
fang lang
I'll have to look at why sg_inq is failing; the bugs that this BZ was cloned from were fixed with a simple patch and I assumed the same patch would alleviate the problems here, but there might be something else causing that command to fail. It seems that this patch did fix `ll /dev/disk/by-id/wwn-*` where it did not work previously. sg_inq *might* be a separate issue. I'll research. It looks as if Linux expects to find the wwn via the ATAPI IDENTIFY and/or ATA IDENTIFY commands, but the sg_inq tool expects to find it via the scsi/atapi inquiry command, in which we do not support for ATAPI entirely correctly.
It might be best to treat this as a separate bug ("IDE ATAPI devices do not respond to VPD inquiries") and fix this there.
