BINGO!!! Alright, here is how this was resolved: I referenced this artice for unmounting the datastore, https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2004605 Step 1: Manually unmount the datastore from the host with this command: esxcli storage filesystem unmount [-u UUID | -l label | -p path ] In ...

This is an HP ProLiant server running with a Smart Array RAID controller without a Flash-backed cache module. As a result, you have no write cache (or read cache), and operations like snapshots of virtual machines will suffer. You've experienced the effect of this. The current configuration is unsuitable for most workloads, especially virtualization. Your ...

This tip worked for me in the past, if you can disable ATS-Only: Cannot mount the VMFS5 datastore when using storage encryption appliances (2030416) I guess no VM are up in your case, but they need to be close to be able to run the command. Some storage encryption appliances may block certain SCSI commands, including ATS commands, sent from ESXi ...

Your storage system is failing or too slow to keep up. If IO has been stalled for too long, Exchange thinks that storage is dead and kills Wininit to force hard reset. See https://technet.microsoft.com/en-us/library/ff625233.aspx and scroll to the end. It's the same for 2013 and 2016. In some cases, the entire storage stack may be affected by the hang, ...

An old config from a vcenter agent must still be there in the esxi, as please see the fact there : Required ports for VMware vCenter Server 5.5 (2051575) 902 TCP/UDP This is the default port used by the vCenter Server system to send data to managed hosts. Managed hosts also send a regular heartbeat over UDP port 902 to the vCenter Server ...

I have the same process on one of my server. I kill it and i delete these files and directories fom /tmp: config.f conf.n \ facebook gameover.so Loader.sh Run.sh scsi_eh_320 They are all done by user "postgres". I search some malware function (\df+) in postgres database but i don't find nothing. The port 5432 is accessible from the internet so I think ...

Use the VMware OSP versions of the tools or open-vm-tools for newer distributions. In both cases, they can be deployed via your yum/apt package manager and could easily integrate into your installation workflow.

As per this document on ESXi 6.0 Configuration Maximums, a single VMFS5 partition has a maximum size of 64TB. There is no limit to the number of devices on the underlying storage as VMware will not be accessing individual disks directly - this will be done by your RAID card. If you will be using RAID0 across all of your 96TB of storage (which is a very bad ...

Ballooning uses a kernel module (installed as part of VMware Tools) to allocate the memory in the guest. So, it is the Linux kernel that consumes the memory, but not one of the regular processes that top would show.

The comments are correct. Your server vendor has to have a CIM or SNMP provider that reports on the hardware health - this could be a VMware driver package, or could be software independent and provided by a management card, like IPMI, iDRAC, or iLO. So it depends on the server vendor's support for such things. If you have a desktop-class machine that you'...

Virtualization is unnecessary to maintain portability if the operating system is modern. Windows 2008 R2 can handle having the hardware changed out fairly well, and Windows 2012 and higher handles it even better. Modern Linux operating systems also don't care about underlying hardware changes.

You can issue a command to disable the ESE forced reboot, the cause is well explained by Don's answer. I did it latelly for a custumer with a single server with esx, as the IO was overkilling the Exchange. (its still killing it, as it take age to simply open a management console in example, but atleast it dont reboot..) Add-GlobalMonitoringOverride -...

It sounds like you're asking if there's a way for a VM on one Standard Switch to see traffic on another, is that right? if so then no, sorry, that's not possible with Standard Switches. You don't even get NetFlow with Standard Switches either so you can't even see the flows, that's just the way the (free) cookie crumbles!

A single broken fan should never cause this kind of "critical" (that's what health light = red means) problem. Your server has probably six hot swappable fans that create a wind tunnel through the chassis, so if five are really up then you should be fine IMO. You need to get a handle on what component is failing/has failed/is getting too hot. Use HP ...

My advice is not to use LAG of any sort unless you're using a VMware distributed switch and have the right licensing environment to take advantage of it. Single-host ESXi static link-aggregation is not going to do what you think it will. If you need more bandwidth, move to 10GbE networking. You're not going to be able to be more than that from the setup you ...

You are not lackng anything with open-vm-tools and will potentially avoid issues when doing kernel upgrades by upgrading open-vm-tools at the same time. vCenter should see open-vm-tools once they are running. Have you check to make sure the service is running after installation? systemctl status -l open-vm-tools if not running start and enable it `...

Make sure that you have both a USB controller and the device itself added to the virtual machine in order to make the pass-thru option work. It would be an easier setup though to not use hardware pass-thru. Instead make sure you have the proper USB controller on the virtual machine and VMware tools have been installed. VMware tools will provide the drivers ...

ARP resolves ip addresses to MAC addresses on behalf of hosts needing to communicate with other hosts on an Ethernet network. The ESXi host doesn't communicate with the guest virtual machines and would have no need to ARP for any of the virtual machines, and therefore shouldn't have any ARP entries for the guest virtual machines. The virtual switch is like ...

Can you give more information about the actual networking issue you're facing? I just ran the same command on one of my busy systems and see physical information on the management and storage interfaces; nothing related to the guest networks: [root@c2-esx1:~] esxcli network ip neighbor list Neighbor Mac Address Vmknic Expiry State Type --...

Before you read it, do note that this feature was intended for VMware Support. While it is internally supported, you’d be using it at your own risk, and consider this write-up to be purely for educational purposes. Support for this feature, and exposure through the UI, may or may not change in the future. I have memory pages swapped, can vSphere unswap ...

The response about LACP not being supported by standard vSwitch is correct. Etherchannel is supported by vSwitch though. So you're probably wondering what's wrong with etherchannel? When teaming with etherchannel, a single TCP/UDP session will not enjoy the aggregate bandwidth of all links in your channel. It will be limited to a single link. So if you ...

@joeqwerty Yes you are right, you can reach the box via different VLAN and or IP block. It does not matter, even so if you use one virtual switch with multiple adapters, then you can override the active-passive adapters. This is how you create round-robin connection for iSCSI adapters, for example. So always one adapter active for the current IP address and ...

This does seem kind of round-about, do I have any better options? Your general idea is spot-on. I would personally suggest using ZFS with Solaris or FreeBSD, but mdadm might also work. Maybe though you don't get all the advantages I write about in this post, so take that as a disclaimer. This post will be quite long, I apologize in advance for the wall of ...
