VNX Unisphere Java Issues

February 14, 2016

java_foreverIf you are a systems engineer, I’m sure you have to deal with Java compatibility issues all the time as I do. You install a certain Java version to fix one client and it immediately brakes another one.

I reached a new level of ridiculousness when I had a customer with two EMC storage arrays, VNX1 in production and VNX2 at DR. One Java version worked for Unsiphere client on VNX1, but broke VNX2 client and vice versa.

This was quite painful until I found a solution on EMC community forums. There is a Java version which works for both arrays and it’s Java 7u51. I have tested it on the following Block OEs and it works like a charm:

  • VNX1 Block OE 05.32.000.5.209
  • VNX2 Block OE 05.33.008.5.119

Let me know if this helped you as well.
