We have 2 servers (windows 2012 Datacenter) connected to a shared storage array using Fibre Channel (EMC CX3-20C). Currently there are 20 Luns on the storage device witch presented to both the node.
We can able to add 18 LUNs as cluster disk in windows 2012 cluster. We are facing issue for 2 LUNS which not showing in “ADD Disk” wizard. Both the LUN2 are visible and accessible in Disk Management on both the cluster nodes. Both the Disks are basic disk.
We have run cluster validation wizard for storage testing. Both are disk are showing under “List Potential Cluster Disks”. But whenever we are trying to add using “ADD Disk” wizard disk is not showing in Wizard.
We have unmap and remap both disk to server and also tried to add disk using power shell command also but no Luck.
Please help us to understand how to troubleshoot this issue.
Thanks in Advance
