EMC VNX/MCx Storage Pool Expansion – NavisecCLI or Unisphere
Storage Pool Expansion on EMC VNX/MCx arrays is a simple, straightforward task that can be done to increase capacity, performance or both. It is an online operation (NDU) but I always try to initiate it when load on an array is non-peak. The process is just like a Fast VP Continue Reading

EMC VNX – Auto Array Configuration Backups using NavisecCLI and Powershell
Following on from yesterday’s EOY backup topic for ESXi, today I’ll document how to automate the backup of your VNX & VNX2 Array configurations.
