Just to make them public, not meant for merging: The scripts used during development to create a bunch of SCSI devices in dom0 using the Linux target framework. targetcli3 and rtslib3 is used. A patch is required for python-rtslib: http://article.gmane.org/gmane.linux.scsi.target.devel/8146 Signed-off-by: Olaf Hering <olaf@xxxxxxxxx> --- tools/misc/Makefile | 4 + tools/misc/target-create-xen-scsiback.sh | 135 +++++++++++++++++++++++++++++++ tools/misc/target-delete-xen-scsiback.sh | 41 ++++++++++ 3 files changed, 180 insertions(+) diff --git a/tools/misc/Makefile b/tools/misc/Makefile index c4490f3..3d5d75f 100644 --- a/tools/misc/Makefile +++ b/tools/misc/Makefile @@ -34,6 +34,8 @@ INSTALL_SBIN += $(INSTALL_SBIN-y) # Everything to be installed in a private bin/ INSTALL_PRIVBIN += xenpvnetboot +INSTALL_PRIVBIN += target-create-xen-scsiback.sh +INSTALL_PRIVBIN += target-delete-xen-scsiback.sh # Everything to be installed TARGETS_ALL := $(INSTALL_BIN) $(INSTALL_SBIN) $(INSTALL_PRIVBIN) @@ -44,6 +46,8 @@ TARGETS_COPY += xen-ringwatch TARGETS_COPY += xencons TARGETS_COPY += xencov_split TARGETS_COPY += xenpvnetboot +TARGETS_COPY += target-create-xen-scsiback.sh +TARGETS_COPY += target-delete-xen-scsiback.sh # Everything which needs to be built TARGETS_BUILD := $(filter-out $(TARGETS_COPY),$(TARGETS_ALL)) diff --git a/tools/misc/target-create-xen-scsiback.sh b/tools/misc/target-create-xen-scsiback.sh new file mode 100755 index 0000000..96d4c39 --- /dev/null +++ b/tools/misc/target-create-xen-scsiback.sh @@ -0,0 +1,135 @@ +#!/usr/bin/env bash +unset LANG +unset ${!LC_*} +set -x +set -e + +modprobe --version +targetcli --version +udevadm --version +blockdev --version +parted --version +sfdisk --version +mkswap --version + +configfs=/sys/kernel/config +target_path=$configfs/target + +num_luns=4 +num_hosts=4 + +case "$1" in + -p) + backend="pvops" + ;; + -x) + backend="xenlinux" + ;; + *) + : "usage: $0 [-p|-x]" + if grep -qw xenfs$ /proc/filesystems + then + backend="pvops" + else + backend="xenlinux" + fi + ;; +esac + +get_wwn() { + sed ' + s@-@@g + s@^\(.\{16\}\)\(.*\)@\1@ + ' /proc/sys/kernel/random/uuid +} + +if test !
