Yes navicli supports both 5400 and 5500 Check if you have a recent version installed – a navicli version back from the VNX1 days could have problems with a VNX2  Another option for monitoring would be UniSphere Central – which is free of charge for VNX customers and supports both You can download it from support.emc.com and give it a try
Hi  I have both VNX 5400 and 5500 which I'd like to monitor via the company's Nagios instance. What's my best option? Is there Linux CLI or SNMP available?  Thanks, Gil
