Currently, the volume groups created on iSCSI devices are not automatically scanned when iSCSI LUNs are discovered. Therefore, during the system boot, the volume groups that were created on the iSCSI devices are unavailable. To overcome this problem, a helper script is provided in /usr/share/doc/packages/lvm2/ lvm-vg-to-udev-rules.sh.
You can use this script to generate udev rules for iSCSI Logical Volume Manager (LVM) devices, which can be automatically mounted during system boot.
After completing the preceding steps for each logical volumes, the logical volumes can be automatically mounted by adding entries in /etc/fstab.
