Disk x will not be used because it is a redundant path for disk y

Event ID: 59
Disk 7 will not be used because it is a redundant path for disk 2

The above warning comes when there is a problem with the multipathing software or problem in storage level zoning.

Windows can detect if a lun has multipule path, sytem activly uses the first path and keeps the other path for redundancy. Incase if there is a problem with multipathing software or miconfiguration in zoning, we may see two disk of same size in diskmgmt.msc.

We need to check if both x and y disks are of same size on diskmgmt.msc and the status of both the disk.

Acction Plan
1. Zoning configuration need to be checked and rectified.
2. Multipathing software need to be reinstalled.
