Upgrading EMC Unity OE

The EMC Unity features an active/active controller configuration designed to allow for non-disruptive software updates. However, it is still best practise to mitigate the risk by performing software updates out of core business hours. In this post we will quickly run through an Operating Environment (OE) upgrade for a newly commissioned Unity 300 array; which was installed using the EMC Unity Setup Guide. Arrays shipped with v4.0.1.8404134 include a letter advising the administrator to upgrade the software due to an issue with this version of the OE. The latest OE can be downloaded from EMC Downloads, you will need an EMC account for access.

From the Unity dashboard select the settings gear and click Software Upgrades, the current version will be listed. Click Start Upgrade. To ensure the system is ready to be upgraded click Perform Health Checks, address any issues that arise from the health check, otherwise click Next.


Browse to the gpg file downloaded earlier, once uploaded click Next.


Confirm you are happy for the storage processors to individually reboot and click Next.


Review the details on the summary page and click Finish.


The software update will now commence, an ETA will be displayed in the top right hand corner.


When the upgrade has completed click to Reload Unisphere, you will be returned to the dashboard. Click the settings gear again and Software Upgrades, verify that the installed version number is correct.


The software update is now complete. You can also update disk firmware by selecting Disk Firmware from the settings menu and following the same steps outlined above.
