PowerCLI Script to Set DNS and NTP on ESXi Hosts

Since joining VMware, I've built, rebuilt and updated several lab environments (home lab and work labs).  One of the problems I keep running into is incorrect/missing/disabled NTP on my ESXi hosts.  Because lab gear is often abused well-loved, BIOS time is not always correct (long periods of being powered off), settings are all sorts of jacked up (it's a lab, we're engineers, let's break stuff!!!), and documentation is non-existent.  The problem is not just in a lab environment - the number of customer environments I've seen that aren't set to use NTP is much higher than I would have thought … [Read more...]

Cleanup Archived Event Logs with PowerShell

I ran into an environment today where a group policy object (GPO) was configured at the domain level that set security logs to be archived to the C: drive when full.  The need for the policy abated, then the policy was removed.  But, the setting to archive event logs on each server and workstation in the domain persisted.  Hard drives - physical and virtual - began to fill up, taking down critical services.  The fix was easy, but I thought I would share for others who might run into the same issue.

I've had several customers ask me for help with the VMware View environment recently, as their users were complaining about performance issues when dragging a window between monitors in a multi-monitor VMware View setup.   Performance was otherwise acceptable on the View desktops.  I recommended several troubleshooting and remediation steps to get windows to stop slowing down when dragging between monitors or "catching" on the border between the two screens, including: Review the "Multimonitor PCoIP sessions are not displayed as expected KB article" (1030566) from VMware. Monitor PCoIP … [Read more...]

Free SAN Monitor for DS3300, MD3000i and others

One of my most popular posts to date had been IBM DS3300 Write Performance Problem Solved.  I am pleased to have upgrade my internal environment to an EMC Clariion CX4 array, but still have customers using the DS3300 and the MD3000i from Dell.  For that reason, I keep an eye out for news on these arrays.  You'll recall that these arrays are based on the same LSI kit.  Truth be told, properly designed and configured, these arrays are a technically proficient and cost efficient solution for SMB's looking to get their VMware environments going. While reviewing my email today I found an email … [Read more...]
