However, I'm still left wondering why we are adding PQ=1, PDT=0 devices in the sequential LUN scan at all.
Are there media changer devices out there that we've seen respond like this? Even so, does it make sense
to add PQ=1, PDT=0 LUNs for LUN > 0?
Yes, unfortunately we need this. NetApp arrays have a habit of
returning 'PQ=1' for unconnected LUN 0, even though higher LUNs are
present. So we need to add devices for PQ=1, otherwise we wouldn't
be able to scan them.
We _might_ be able to tweak this by ignoring devices with PQ=1 and
LUN!=0; however, it might break other things.
Hello Hannes,
The code in scsi_scan.c already skips LUNs with PQ=1 and PDT=0x1f. I'm
not sure we should skip LUNS with PQ=1 and a PDT value other than 0x1f.
Thanks,
Bart.
