CMMNP5101E Disk not viable.

Explanation

The LUN given by the device name is not viable as a volume. The properties of the LUN make the addition of the volume to a storage pool not viable. Potential reasons include:
  • The LUN does not hold at least one partition.
  • The local operating system device name is not viable as a global disk.
  • Hashing using World Wide Name (WWN) conflicts.
  • The sector size is less than 512 or greater than 4096.
  • If it is being added to the system pool, the sector size is not the same as the other volumes in the system pool.

Action

Make sure that the LUN is configured appropriately and attempt to create the volume again. Alternatively, you can select another LUN.
