Sysadmin Stories: July 2013

http://ravatheodor.blogspot.com/2013_07_01_archive.html

Monday, July 1, 2013. TCP ports "greater than 65535". It is TCP port 73382. And the connection works (more or less optimal, but it works). But what actually happens is the interesting part. The connection in the image is a port translation from 73382 to 3389. This means there is a device doing the translation - in our case a linux box. And there is a program listening on port 73382. Well, not exactly. There are client programs that using a simple input check do not allow using strange numbers, however RD...

Sysadmin Stories: June 2013

http://ravatheodor.blogspot.com/2013_06_01_archive.html

Thursday, June 20, 2013. Command line upgrade of ESXi 5.1 to 5.1 U1. The reason I`ve chosen this method is not having VUM installed and also wanting to remember a bit of esxcli. The process is pretty simple:. Download the zip bundle (update-from-esxi5.1-5.1 update01.zip) and put it on a datastore accessible by all hosts (I am using a NFS share). Check to see if the host has the datastore mounted, if not - add the datastore. Esxcli storage nfs list. Check the host version. Esxcli system version get. I`ve ...

Sysadmin Stories: Distributed virtual switch IP hash mismatch warning

http://ravatheodor.blogspot.com/2014/10/distributed-virtual-switch-ip-hash.html

Wednesday, October 22, 2014. Distributed virtual switch IP hash mismatch warning. While migrating a standard switch to a distributed switch I've enabled health check for Teaming and failover. In the migration wizard, there are no errors displayed on impact analysis screen, so I just pressed GO! The host is migrated and I get the following warning: IP Hash mismatch. At this point I get a bit confused - where is that coming from? I've changed the policy, refreshed the view and the warning disappeared.

Wednesday, June 12, 2013. Command line installation of vSphere Auto Deploy.

Saturday, January 26, 2013. PowerCLI - Starting and stopping SSH. From time to time I need to go connect on the ESXi using SSH. I know it is not best practice, still I have to do it. And the most simple task transforms into a pain - starting and stopping SSH server on several ESXi hosts. The following small piece of PowerCLI does the job just fine:. Get-Cluster CLS01 Get-VMHost Get-VMHostService Where {$ .Key -eq "TSM-SSH"} Start-VMHostService. Wednesday, January 23, 2013. Go to VM - Edit Settings. A res...

Wednesday, January 11, 2017. Veeam VMware vSphere Web Client Plug-in. Somehow I keep on getting back to restarting this activity, which is very rewarding, but also time consuming.

First, let me start with a disclaimer: the posts and opinions herein are my own. Not representing the company I work for, or the vendor, or anything official.

Wednesday, February 27, 2013. NetApp SnapMirror traditional volumes to flex volumes. VSM: TradVol - TradVol and FlexVol - FlexVol. QSM: TradVol - TradVol, FlexVol - FlexVol and TradVol - FlexVol. For each filer, check the license for snapmirror exists, if not added it:. Filer1# license add XXXXX. Filer2# license add XXXXX. Make sure that each filer is resolvable in /etc/hosts file (a best practice is to mount /vol/vol0 and edit the files, else use the infamous rdfile and wrfile commands). Synchronization...

Sysadmin Stories: VMware DirectPath I/O - adding passthrough PCI devices to VM

http://ravatheodor.blogspot.com/2013/01/vmware-directpath-io-adding-pasthrough.html

Wednesday, January 23, 2013. VMware DirectPath I/O - adding passthrough PCI devices to VM. VMware DirectPath I/O allows guest OS to directly access physical PCI and PCIe devices connected to host. There several things to check before proceeding to configuration:. The maximum of PCI devices that can be attached to a VM is 6. The VM hardware must be 7 or later. Intel VT-d or AMD IOMMU must be enabled. PCI devices are connected and marked as available. Device/000:000:27.0/owner = "passthru". Removal of PCI ...
