Powered down SAN environment over the weekend. Normal, graceful shutdown using prescribed IPL procedures. Powered back on and all but two v/m are operational. v/m NIC won't stay connected even after selecting and allowing for v/m modification. Both v/m's reside on same ESX host. Have re-installed NIC, changed vlan, disable/enable NIC all without success. All three ESX hosts are operational. All v/m's on host (except the two) are operational.
SAN: EMC Clariion CX3-10, Dell PE 6850/R900 systems, ESX 3.5.0 123630, VMware Tools v123630, Guest O/S W2K3 R2 SP2 Std Ed
Yes, w/o success. Have disabled/enabled NIC (error 4703 in event viewer) and changed vlan. All w/o success. The ESX host servicing the problematic v/m's also holds 23 other v/m's with no problems. Just these two.
Are you setting the MAC address inside the guest OS? Try modifying your vSwitch policies to allow forged transmits and mac address changes.
Does the mean that the ports across all switches need to be identical. I'm having the same issue.
When I edit the virtual machine and select 'connect' for the nic, its save the setting but if I got back into edit setting it show the settings didn't stick.
