Configuring the EMC Unity data collector

Contributors netapp-alavoie

The DELL EMC Unity (formerly VNXe) data collector provides inventory support for VNXe unified storage arrays. Data Infrastructure Insights currently supports iSCSI and NAS protocols.

Requirements

  • The Unity data collector is CLI based; you must install the Unisphere for Unity CLI, (uemcli.exe) onto the acquisition unit where your VNXe data collector resides.

  • uemcli.exe uses HTTPS as the transport protocol, so the acquisition unit will need to be able to initiate HTTPS connections to the Unity.

  • IP address or fully-qualified domain name of the Unity device

  • You must have at least a read-only user for use by the data collector.

  • HTTPS on Port 443 is required

  • The EMC Unity data collector provides NAS and iSCSI support for inventory; fibre channel volumes will be discovered, but Data Infrastructure Insights does not report on FC mapping, masking, or storage ports.

Troubleshooting

Some things to try if you encounter problems with this data collector:

Inventory

Problem: Try this:

"Failed to execute external utility" with error messages “Failed to find Unisphere executable uemcli”

* Verify correct IP address, username, and password
* Confirm that Unisphere CLI is installed on the Data Infrastructure Insights Acquisition Unit
* Confirm that Unisphere CLI installation directory is correct in the datasource configuration
* Confirm that the IP of the VNXe is correct in the configuration of the datasource. From the Data Infrastructure Insights Acquisition Unit, open a CMD and change to to the configured installation directory: ${INSTALLDIR. Try to make a connection with the VNXe device by typing: uemcli -d <Your IP> -u <Your ID> /sys/general show
