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?
Yesterday 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.
