Hi Alan,
you said that the "scsi add-single-device" code is horrible and gets
overhauled...
Some weeks ago I noticed that I loose tagged command queueing (TCQ) on my
harddisks when I dynamically add a device with "scsi add-single-device" and
posted it to linux-scsi but nobody answered... sigh. I have this with
2.2.1[123] on an adatptec 2940. Although the harddisks use TQC with a queue
depth of eight (at least /proc/scsi/aic7xxx/0 reports it) the rescan on
"scsi add-single-device" bumps the disk-queues to a depth of one. :-(
Will the "overhaul" cure this?
P.S.: Hope you'll be well soon. Have some more curry... ;-)
Mit freundlichen Gruessen / best regards
