HPE CLX Virtual Machine Protection Fails

Recently a colleague was attempting to configure the cluster extension protection (CLX) which is required by our Active/Active HPE 3PAR storage setup.

We use the CLX software to manage … Read more

Trend Micro ScanMail Virtual Analyzer Connection Troubleshooting

I’ve been working on our Trend Micro Deep Discovery Analyzer (DDAN in Trend parlance) and today I finally finished off the virtual image which it will use to sandbox suspicious files/URLs. Having finished that work I figured I’d take a look at integrating our Trend Micro ScanMail for Exchange (SMEX) systems so that e-mails can … Read more

Unexpected Large Page File Troubleshooting

This week one of my colleagues has been performing updates on our hypervisor hosts including those running Hyper-V. During this work we received alerts from our monitoring system to indicate two of the hosts had essentially run out of disk space, obviously a little worrying.

HPE 3PAR Remote Copy Volumes Both Read Only

I recently ‘enjoyed’ working on an issue where a 3PAR remote copy group issue resulted in both virtual volumes entering a read-only state.

Nexsan SATABeast Password Reset via Serial Interface

Kali Linux VMware ESXi Console Window Scaling Fit Guest Now

Unfortunately it didn’t work and for a … Read more

Set Cluster Log Size and Verbosity in Microsoft Server 2008 R2

Recently a critical cluster system had a bit of a hiccup wherein the SQL resource failed between nodes a few times and then gave up. Most of my clusters run on Microsoft Server 2012 R2 so I tend to use PowerShell for everything, in this case the cluster is an older one running Server 2008 … Read more
