cluster node 1 is having disk performance issue in the SQL DB when cluster node 1 becomes the Active node.
while in cluster node 2 there is no disk performance issue when it becomes the Active node.
DB team claims that when they try to create a DB file normaly it takes only 75 seconds because of the disk performance issue it has been delayed to 700 seconds.
The storage used is EMC Symmetric VMAX, the storage team claims that there is no issue from their end, as the the same LUN is used by node 2 which works fine
but in node 1 its not. so they says that its not from storage side. Any idea...?
