Hi there,Add the Xserve with the BLIST_SPARSELUN flag into the blacklist/quirks table in drivers/scsi/scsi_scan.c
We have an Apple Xserve RAID, connected through a FC switch. The RAID has LUN-masking enabled, such that one of our Linux boxes only gets LUN 1 and not LUN 0. We're running the 2.4.x kernel series now, since this is under a RHEL envinronment.
The problem is this: since LUN 0 does not show up -- specifically, it can't read the vendor or model informaton -- the kernel SCSI scan does not match with the table to tell the kernel to do sparse LUN scanning... so the RAID does not appear.
I can make the RAID show up by injecting a add-single-device to the SCSI proc layer. Trivially patching scsi_scan.c to always do sparse scanning works as well. No hokery with max_scsi_luns or ghost devices works.
I'm considering making a patch to add a kernel option to force sparse scanning. Is there a better way?
