I have an enviroment which has VI 4 and ESX servers on vSphere 4 (In cluster1). The other Cluster (cluster 2) has a number of esx 3.5 servers. After using update manager to fully patch each esx 3.5 host, the hosts are unable to connect to the NAS (where all VMDK files are located).
Cluster 1 is not connect to a NAS but a SAN, so no issues there.
Has anyone had this issue.
I'm lucky as I have 1 esx 3.5 holding all the VMs, and I'm not going to update this. But I need the VM machines to connect to the NAS.
Try to add the datastore again. You don't need to remove the first instance.
I can't as it can't see any of the luns, nor the paths to the NAS
First verify that you have the connectivity of NAS with cluster1. Ping the NAS server from ESX4 server, if communicate, readd the NAS storage through vCenter4, make sure you won't format any thing on the NAS server. If it doesn't add the storage, look for the errors in vmkernel....
