I am using vcloud director and  i am using vcenter& Vshield  with storage profiles with NFS storage , due to switch upgradation of NFS .There is some disconnection between NFS shares & ESX host due to that all my environment Network is disconnected , is there any process to r-connected all the nework  automatically ...

I tried stop and start  the Vapps , Network is running back .. and i did'nt see and Read only issues in Linux Vm 's , Could some one suggest to resolve the issue .

There is some disconnection between NFS shares & ESX host due to that all my environment Network is disconnected , is there any process to r-connected all the nework  automatically ...

1) Are you able to connect to NFS exports now ?

2)What do you mean by reconnecting all the networking automatically ? Apart from NFS shares in vSphere environment ,where-else are you using it ? VCD(TransferStorage) ? 

3) Is this the same switch for management and other VM traffic ?

I tried stop and start  the Vapps , Network is running back .. and i did'nt see and Read only issues in Linux Vm 's , Could some one suggest to resolve the issue

Please let me know what is the issue now ?

You say "I tried stop and start the vApps and the network is running back".

From that I'm assuming that you're running vApp networks with services enabled (like NAT, DHCP, routing or whatever) and when the connectivity to your NFS storage failed, your vApp networks became disconnected?   When you stopped the vApp, this would have shut down all the VMs inside the vApp, powered down and unprovisioned (i.e. deleted) the VM that runs the services for the vApp network (basically a small version of a vShield Edge VM).  When you started the vApp up again, the vApp Network service VM would have been redeployed, powered up and the config pushed down to it.

I've found Linux VMs to be fairly intolerant of storage outages.  Often the filesystems will go read only and require a reboot/re-mount to bring them back in read/write mode.  The same is true for the vShield Edge / vApp network service VMs.  If those experience an issue with underlying storage, they'll have issues until they're rebooted.

Unfortunately I'm not aware of any method to have the vShield/vApp firewalls automatically rebooted if there is an issue like this.  I would concentrate on making sure your NFS implementation can survive the failure (or in this case planned outage) of a single switch.
