![]() ![]() ![]() Ping was working from one VM to another on the host that was messed up. as-in not able to ping from a physical computer hooked up to the switch stack. it was from anywhere outside of the host. I have since reconfigured the ports on the Cisco switch for the LAN vswitch to be in an Etherchannel and reconfigured the vswitch settinga on the host as well as reconfigured the port group for the management port on that host.Īs for not being able to ping any of the VMs. I really don't like taking over setups from other people when there is absolutely 0 documentation on why they set stuff up the way they did. Not sure why it wasn't messing up with the old hosts. Im able to boot in Legacy Boot Mode from the new SAN but when trying to use UEFI Boot mode I can install ESXi but once that completes it reboots and enters the BIOS screen of the B200. We are migrating to a new SAN storage and in the process working on vSphere upgrades. so maybe it was the port group that was crapping out and not the vswitch. Looking for a little guidance on getting ESXi 6.7 to SAN boot in UEFI mode. Pretty sure the Cisco switch was crapping on this and making it not work though the management port which was on the same vswitch was working. "spanning-tree portfast" was set on the ports. Power off or reboot the messed up host and PXE booting starts working again. systems say that the media is connected but it never gets past the MAC address screen. Has anybody ever seen this type of behavior before or have any ideas besides what I am going to try?Įdit: Noticed another very, very weird thing that happens when the vswitch dies - I am unable to PXE boot. The PXE process on the host server chainloads the ESXi boot process using the supplied image file and configuration settings. and they have the network temaing set up differently. I will be changing that tonight since I upgraded another location with the same exact hosts and we have not had a single problem with them yet. Then today, one of the hosts messed up again.Ĭurrently these hosts have the network teaming to only failover and not load share. I already had a 3 hour support call with VMWare and they though that it had to do with VLANs so we changed that and it started working without rebooting the host so we thought we had fixed it. Then it works again for a few days to a few weeks and then dies again. To get the vswitch working on the host that messed up, we have to reboot it. ![]() If we migrate them without powering them off first, they do not regain a proper network connection. If we power off the VMs and migrate to the other host they work fine again. None of the VMs on that host using that vswitch are able to be pinged. it happens on both, but never at the same time. In the one location, the LAN vswitch basically just dies on one of the hosts. we have a couple identical Dell Poweredge R7515. The Network boot option is unavailable.Sooooo. Power on the virtual machine and boot into the virtual machine’s BIOS. The network boot is only disabled for that NIC. Note: If you have multiple NICs in e1000 specify the NIC number for disabling. If the virtual machine is using an e1000 device, append the line ethernet0.opromsize with “true”. Note: This disables network boot for all VMXnet NICs. If the virtual machine is using a VMXNET device, ensure you append the corresponding line below depending on the VMXNET device used. For more information, see Tips for editing a. Open the virtual machine’s configuration (/vmfs/volumes/.vmx ) file in a text editor. To remove Network boot from appearing in a virtual machine’s BIOS: Make your VMs boot faster and disable PXE booting! This KB article explains how to do it.Įcho "ethernet0.opromsize = \"0\"" > \.vmx ![]()
