Add Additional DAE to an existing DPE for AX4-5i
Hello Team,
We are planning to upgrade our EMC Ax4 storage array(Dell) with additional capacity. We have to add another DAE to the DPE, we have all the ports and necessary cables ready. I came to know that we need "expansiontier" license to visible the upgraded capacity on Managment Console. Can someone please let me know the process to add DAE to a DPE for AX4-5i
I have not been able to find an installation document for adding a new DAE to an SX4-5i. Did you check to see if the new DAE came with any documentation?
You need to contact someone that has done an install before, maybe a local EMC office or the company where you bought the AX4 from?
Generally the installation of a new DAE is to shutdown the array (powered off). The cable the new DAE to the existing DAE - there should be "In" and "Out" connectors for the SAS cables. Each DAE has a unique DAE address and the new one should be set to the next higher number - this is located on the back of the DAE.

Unisphere Service Manager will offer you a guided procedure for adding the DAE to a live system. As I recall you will power up the new DAE, and then USM will have you connect first one side, and then the other, to the DPE.
Certainly something that you should do during quiet/off-hours, but technically non-disruptive.
