New LUN Not Visible in Multipath

(Doc ID 2297447.1)

Applies to:

Linux OS - Version Oracle Linux 7.0 and later
Linux x86-64

Symptoms

Presented a new 500GB FC LUN to an Ooracle Linux 7 system which uses multipath software.

The LUN is visible in the Linux OS (fdisk shows /dev/sdf), but multipath is not listing that disk.

This server already has some older LUNS that uses multipath and no issues there. The new LUN is from the same storage.

Need to make the new LUN visible in multipath as well.
