I have an Storwize V7000F 2076-AF6 that I could update to FW 188.8.131.52.
Now I try to update it to FW 184.108.40.206 and the upgrade process fails with the message:
"The system is unable to install the update package.
The specific update package cannot be installed on this hardware lever"
I don't understand why, because in the IBM compatibility matrix V8.3 appears as the recommended version for 2076-AF6 machines.
Not sure if this is the REASON that upgrade to 220.127.116.11 is failing, but...
The matrix you refer to (https://www.ibm.com/support/pages/node/690527?mhsrc=ibmsearch_a&mhq=spectrum%20virtualize%20upgrade%20planning) says that the MINIMUM PTF/firmware is 18.104.22.168 for V7000 Gen2. (276-AF6 is actually a V7000 Gen2+.) 8.3.0 is basically deprecated, and should not be installed on any Storwize systems. 8.3.0 codestream has not had an update in over 2 years, and is replaced with 8.3.1.x.
Recommended version, per matrix, is 22.214.171.124.
