retest found when found when lun increase stepping is 63, only the first disk detected by guest, other not; for other stepping all disk detected in guest; so correct bug title; sorry for incorrect info in comment#0; thanks, Xu qemu-kvm-1.5.3-10.el7.x86_64 After checking the command line, only the lun is assigned as 0, 1, and then the rest disks are increased by one at every step, the disks can be recognised. ............ -device virtio-scsi-pci,id=virtio_scsi_pci0,addr=0x6 \ -drive file='/tmp/stg0.qcow2',if=none,id=virtio-scsi2-id0,media=disk,cache=unsafe,snapshot=off,format=qcow2,aio=native \ -device scsi-disk,lun=0,drive=virtio-scsi2-id0 \ -drive file='/tmp/stg1.qcow2',if=none,id=virtio-scsi3-id1,media=disk,cache=unsafe,snapshot=off,format=qcow2,aio=native \ -device scsi-disk,lun=1,drive=virtio-scsi3-id1 \ -drive file='/tmp/stg2.qcow2',if=none,id=virtio-scsi4-id2,media=disk,cache=unsafe,snapshot=off,format=qcow2,aio=native \ -device scsi-disk,lun=2,drive=virtio-scsi4-id2 \ -drive file='/tmp/stg3.qcow2',if=none,id=virtio-scsi5-id3,media=disk,cache=unsafe,snapshot=off,format=qcow2,aio=native \ -device scsi-disk,lun=3,drive=virtio-scsi5-id3 \ ............ retest qemu-kvm-1.5.3-60.el7.x86_64 with rhel7.0, rhel6.5 guest, disks list in guest. But in rhel6.4 guest, only lun id less that 255 can be list in guest. Hi Fam, does this mean rhel6.4 kernel only support 255 scsi disk? if so I thinks this bugs can be closed. thanks, Xu Closing this bug because it is not reproduced in RHEL 7. For RHEL 6.4, 256 should be the limit of targets, and the limit for luns per target is 16384, according to the virtio-scsi specification. Fam |
