I refer you to two threads which discussed the issue. http://marc.theaimsgroup.com/?l=linux-scsi&m=115386616817044&w=2 http://marc.theaimsgroup.com/?l=linux-scsi&m=115266599732078&w=2 Mike James Bottomley wrote: > On Mon, 2006-07-31 at 12:20 -0500, Michael Reed wrote: >> mptscsih_slave_destroy issues an unconditional synchronize cache. > > A) mptscsih_slave_destroy shouldn't be doing this ... it should be > relying on the functionality in the mid-layer. > >> It is not necessary for fibre channel devices for which the rport >> has been deleted.
