This now becomes the 3rd post regarding the infamous Changed Block Tracking bug that was/is evident in all versions of ESXi 4+. If you missed them, Part 1 & Part 2 Finally today we see the bug squashed in ESXi 5.5 with the release of Patch ESXi-5.5.0-20150104001-standard (2099271). This still leaves 4.x susceptible though so I […]
Nothing groundbreaking here folks, but this is a quick and easy way to upgrade the drivers (in this case Network Intel & Broadcom) on your host(s) I’ve done this many times for various reasons: Misbehaving drivers after upgrades, Version control, “’cause I wanna'”. etc Login to your host with the ssh client of choice (putty […]
This is the second time I have had EMA technical advisories recently regarding issues with 15k SAS disks. The first one I wrote about here. It doesn’t sound quite as serious as the last one (OMG, DATA LOSS), but worthy of a look and fix. Details; and full link here and excerpt just below “” EMC Technical […]

A similar issue surfaced this week, this time when attempting to access a VNXe 3150, when I was greeted with the following message; Tests from multiple hosts and browser versions […]

This is an important release as finally environments that are on 4.x have a validated upgrade path to 4.1/SE that will pass the EMC mandated change control process, which has been many months in the […]
I was doing a fresh RecoverPoint 4.1 install recently, and everything wet very smoothly up until I attempted to enter the vCenter server details under the “Register vCenter Server” dialog. History shows this has been a little bit goofy in the past, with the MUI certs and credential entry known to be stubborn, but usually […]
I had a nice little episode with a set of PSOD looping hosts in December which resulted in a lot of guests getting moved around automatically during attempted HA recoveries.
