Hi Team

We are planning to upgrade OE for VNX 5300 from 05.32.000.5.207 to 217 or higher version, could you please suggest which version is compatible or how do I check the compatibility. A Recovery point also running on this environment. Last week SPS B showing an error light so we replaced SPS and now solid green light is on SPS, BUT on the on the system amber light is on and Unisphere status for SPS B  showing “unknown cabling’’ . So I refer the EMC knowledge base as per this ,we have to upgrade OE to minimum .5.217 or higher version for resolving this issue .so we are planning to upgrade Block version to 5.217 or higher for resolving this issue.so my doubt is:

A> How do I check the compatibility version for my environment for upgrading?

B> I am planning for an NDU upgrade, so what are the pre check I need to take care before I start 

C>A Recovery Point is attached, so how do I check the compatibility version for Recovery point and OE version.

D>Or there is any other solution for without upgrading remove the amber light from the machine.

Best Regards

Thomas.
