FYI: Cisco UCS doesn’t work with VVOLs oob

FYI, ran into an issue tonight working with VVOLs.

I had just upgraded my PureStorage array to Purity 5 GA release and wanted to jump into VVOLs on my lab.

Customers will not be able to use vvols unless they manually install FNIC driver or higher.

VVOLs are not supported on any VICs with the drivers installed from the current Cisco-branded v6.5 and 6.5U1 ESXi ISOs.

This is Cisco bug CSCux64473 Specific cause is because included driver did not support “Secondary LUN IDs”.

If a customer tries, their Protocol Endpoint will just never show up.

Symptom: UCS server with VIC adapter does not support VMware Virtual Volume feature
Conditions: When attempting to access Virtual Volume from UCS servers installed with VIC card.
Workaround: Virtual volume is not supported on any the VIC cards / FNIC drv ( Their but report isn’t totally true, I tested driver and it worked great!)

  1. Latest driver release does work:


Now, after updating the driver and rebooting my servers, VVOLs is working awesome!

PureStorage does VVOLS right!

Big Data – A Need for Speed – Hello PureStorage FlashBlade!

#STBY – DellEMC DataDomain DDos 6.0 Deletes Valid Data

Got DataDomain? Got DD OS 6.0? Your #VALID data may be getting deleted and you don’t even know it!


Segments ingested while the unit is in a cleanup cycle may be deleted, as the unit incorrectly marks them as invalid. You would not know you lost these segments until you attempted to restore!

#STBY – Intel Management Engine (Intel AMT) exploit in the wild CVE-2017-5689

Intel recently screwed us all with the Atom C2000 processors taking a massive crash and burn on end users, leading to all sorts of embedded devices turning into giant paperweights. This week, Intel blessed us with an exploit in the wild hitting their Advanced Management Technology (AMT).

AMT is their ability to remotely configure and control desktop and server systems via web service calls. Firewall off where ever possible ports 16992 and 16993, though if someone get’s inside, it’s a free for all. A Pseudo-Patch has been created. Apply it today!

#STBY – GitLab accidental deletion of data

GitLab certainly had a #SucksToBeYou week. Earlier this week, an admin at GitLab had the same thing happen. Too tired, rm -rf in the wrong location, but unfortunately they had poor backup practices.

Props to them for being upfront.
IF they had Netapp gear, or Cloud Ontap, they could have used SnapRestore or Single-File SnapRestore to pull back the deleted files from snapshots within seconds.

#STBY – EMC Isilon OneFS failure/reboot after 248days

Sucks To Be You! – An Overview

Some days everything goes wrong. It’s not always your fault.

Often, vendors know about problems, and may post about them, or send a communique to vendors or their top superglobomega-corp customers. You are too busy to see them, or not privileged to that information.
This category hopes to be a beacon, a guiding light to what you should know. Learn about issues before you have a day that you feel it sucks to be you.

I’ll primarily focus on Datacenter issues which affect one of my typical customers, typical products we see in virtualization, compute (hyper-converged/converged), storage systems and security.

Post-Insight Wrap-up, Storage Security, and other thoughts!

It’s been a super busy month for JK-47, having just come back from Netapp Insight, TechFieldDay Extra, giving a #vBrownBag Storage Security Lighting Talk, and now getting dozens of customers ready for end of year DR tests and new purchases. This time of year I tend to meet with 10-15 customers a week making sure everything is going smoothly, and also looking over their storage with healthchecks of the past years’ data.
Watch on Youtube:

In the past week, I spent some time talking to NetApp’s Tech ONTAP Podcast. The topic of interest was Storage Security, which I have a great passion for. Listen here:

Thoughts on Education.

I was thinking about education today. The ‘modern’ education system in America. How much it misses the mark in bringing out something special in those whom are our futures. Thinking about how I want my children to learn. I reflected back upon my own experiences, in many different schools across the country.

Some random thoughts on the topic…
