OpenSuse Leap 15 Rescan disks

It is possible on multiple Suse OS (eg Suse 12 SP4) that if a SCSI hard-disk is added at hypervisor level (eg VMWare), it is not automatically reflected in 'fdisk -l' output. To see this disk try:

rescan-scsi-bus.sh -a -l

Note:

• rescan-scsi-bus.sh has lot of options such as --forcerescan which might lead to downtime. Hence avoid using other options of rescan-scsi-bus.sh unless you are sure what you are doing.
• If it is not a production system then reboot should definitely solve the problem of harddisk not showing up.1

Once the disk is visible you can use yast2 -> partitioner for the required file-system changes (Eg resize Volume Group and resize LVM partition)
