Re: Lost access to volume due to connectivity issues.

Hi,

   It not easy to figure whats going wrong just by looking at the error "

I would recommend you to log a case with Vmware or do follow the below steps so that you can narrow down a bit.

1. Check that a rescan does  not restore visibility to the targets. F
2. Determine whether the  connectivity issue is with the iSCSI storage or the fiber storage. Perform one  of the following depending on what your connectivity issue is:
   • To troubleshoot the  connectivity to the fiber attached storage, check the following:
   1. The fiber switch zoning  configuration permits the ESX host to see the storage array. Consult your switch  vendor if you require assistance.
   2. The fiber switch  propagates RSCN messages to the ESX hosts.
   • To troubleshoot the  connectivity to the iSCSI storage using the software initiator:
   • Check whether a ping to  the storage array fails from ESX.
   1. Check whether a vmkping to  each network portal of the storage array fails
   2. Check that the initiator  is registered on the array. Contact your storage vendor for instructions on this  procedure.
   3. Check that the following  physical hardware is correctly functioning:
      • Ethernet switch
      • Ethernet cables between  the switch and the ESX host

      • Ethernet  cables between the switch and the storage  array

3. Check the  physical hardware for the following: etc .....
