VNX Unified standby data mover interface suspended after Cisco NX-OS upgrade

We’re in the midst of a VCE vBlock 340 software upgrade. Part of this upgrade process is upgrading the Cisco Nexus 5K switches that connect the blades and storage to the customer network. After upgrading the switch we suddenly noticed on the switch that the VNX Unified standby data mover (server_3) interface suspended with a “no LACP PDUs” error message. A quick check on the switch that wasn’t upgraded yet showed that interface to be online. So what’s up with that?

VNX Unified upgrade – Where’s that .upg package?

VNX OE for File .upg package selectionA VNX Unified upgrade is fairly easy: Unisphere Service Manager (USM) does most of the heavy lifting. A Block only system is the simplest of all: you upload a .ndu software package to the system and wait for the update to complete.

A Unified system is a combined package of a VNX Block system, and a File component consisting of one or two Control Stations and at least 2 datamover blades. In a VNX Unified upgrade, you first need to upgrade the File part of the system and afterwards the Block part. For the File upgrade, you need to select an .upg package. But… you can’t download this from the EMC/VCE website. Now what?

Building a hybrid cloud with Avere

Avere logoThere’s no denying that off-premises cloud services are growing. Just look at the year-to-year growth of big public cloud providers. There’s big potential if you focus on two aspects of cloud. The first is speeding up access to data that is potentially not located in the same city or even geographic area. The second is supporting new protocols and storage methodologies that are suited for cloud native applications. One player in this area of IT is Avere, which aims to connect on-premises storage and compute to their siblings in the cloud.

Implementation Day 2 – Start the Isilon

You should see something like this after you start the isilonYesterday we racked and stacked the EMC Isilon systems, prepared most of the cabling and pretty much prepared to start the Isilon systems. Which is pretty uneventful if you consider we’ve been dragging along hundreds of kilograms of equipment all day yesterday… The whole process can be pretty much split in four parts: configure the cluster and initial node, join the remaining nodes, configure the network, configure the rest.

Implementation Day 1 – Isilon Rack and Stack

xrayI’m currently contracted by a customer that has been experiencing chronic capacity and performance issues in their storage environment. After analyzing the environment and writing an advisory report we got to work and started correcting and improving many aspects of the storage systems. One component of this overhaul is installing a pair of new Isilon systems which will store PACS (Picture Archiving and Communication System) data generated by the radiology department. The planning and design phase took place over the last couple of months, in which we involved both internal IT people and external resources such as the PACS vendor and the suppliers. All said, discussed and done: the actual implementation of the Isilon systems is scheduled for this week. Today: Isilon rack and stack!
