Lvm2-pvscan service error on Suse LPAR or machine boot

If we see following error while booting Suse LPAR or physical machine:

FAILED] Failed to start LVM2 PV scan on device 254:7.
See 'systemctl status lvm2-pvscan@254:7.service' for details

Then the issue can be resolved by:

Start the lvm2 service manually:

systemctl start lvm2-pvscan@254:7.service

Then resume booting with
```
systemctl default
```
After this the further reboots of the machine did not require above steps again. In future lvm2-pvscan seemed to start properly.
