Consolidate virtual machine disk files failed. Files Locked
Nagios sent us an alert suggesting a virtual machine had a very high load. The OS itself looked fine and nothing appeared wrong with the server itself.

When right clicking and consolidating Read More…
iSCSI Storage in VMware – A Quick Overview
Today I will be writing a very brief overview on iSCSI storage and how it fits into a VMware environment. In this example I will be referring to a small cloud I have set up using a 3 host ESXi (5.1) cluster which connects to an Equallogic SAN using a software initiator.

Setup: 2 ESXI 5.0 hosts, connecting to a Dell MD3200i SAN via stacked Cisco switches. The setup has 3 LUNS. Problem: The small, private cloud with a webserver and backend DB server (amongst a few other servers ) became inaccessible from the outside world via HTTP/SSH etc. Upon inspection it appeared that the iSCSI storage was flapping. vCenter Read More…

We were getting warnings from the SANs LUN is over our warning threshold. However, VMWare was reporting nowhere near that limit. Using the UNMAP facility available in ESXi 5.0u1 + we are Read More…
Intermittent Loss of Connectivity to Storage – ESXi
Network: A small private cloud which containted two ESxi 5.0 hosts and a Dell Powervault SAN connected via stacked Cisco 3750s. A pRDM is attached to one VM which was directly connected through to a QNAP TS-859U-RP+ on the storage network.. Each Esxi host contains 3 VMs. Scenario: All 3 VMs on ESXi1 became unavailble. Ping was still accessible but Read More…
Cannot connect to vCenter Single Sign On Server via Web Client
Problem: None of our users (including admin@system-domain) could log in via the web client. The normal vSphere client was accepting logins.
