Today EMC announced the latest inductees into their EMC Elect program. This is a revered accolade in it’s 3rd year. Read about the program details here. The qualification process is rigorous and peer reviewed. You earn your place. There were 450 nominations, down to 200 finalists, and then only 102 members named. I’m thrilled and […]
It’s HEADS UP! time again, as usual courtesy of an EMC TA bulletin. ‘VMware ESXI hosts may become unresponsive after adding or removing LUNs when running PowerPath/VE 5.9.1’ This doesn’t sound like a particulalry fun way to start or end your day so read on if you want to avoid it; Affected Versions; ESXI 5.1 & […]
GUI’s are generally cool, but when you need to get many of the same/similar tasks done, you can’t beat the speed and ease of using scripts and CLI based tools. I recently had a situation with a EMC VNX2 array where someone (or something) had caused all the LUNs in a RAID Group to become […]
No, not that type of ghost. Just a quick post to collate some info regarding EMC equipment and a recently discovered vulnerability in certain libraries present in some versions of Linux, which are utilized in a number of EMC systems. As usual, this is a buffer-overflow type vulnerability, this time in the glibc 2.2 library […]
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 very quick post this one, but an annoying thing I often see left unchecked in environments, that is simple to fix in a minute. Yes, this is an old topic, but it’s still too evident today…. This should be in your “just do it” category. It’s the awful Certificate warning displayed in your Powershell […]
It wasn’t so long ago that I had some login issues when trying to connect to one of the VNX boxes I manage via Unisphere. 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 […]
No sooner had I written this post, EMC release Service Pack 1 for RecoverPoint 4.1 with the fix included. 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 […]
