If you have EMC CX4 storage and are using Mirrorview, I suggest you hold off any Flare upgrades past 009 unless directed by EMC Technical Support. Some EMC customers have had issues with 012 including serious Mirrorview performance problems.
EMC engineering have pulled version 009 and prior from Powerlink due to “emc261544: Detecting memory leaks with Pool LUNs in FLARE Release 30.” which is resolved in FLARE Release 04.30.000.5.511 but this code introduces another different issue, the management server requires reboots from time to time to allow Unisphere management.
There is also a required frumon update (emc261645-01.01.5.002-fleet64_free) for LCC to version 7.85 to protect against possible dual Power supply failure, this is unlikely but bad stuff does happen.
The following are some handy naviseccli commands, replace username, password and the 192.168.0.1 with your storage log in details and IP.
Check the FRUMON code level on the LCC’s
naviseccli -scope 0 -user username -password password -address 192.168.0.1 getcrus –lccreva
naviseccli -scope 0 -user username -password password -address 192.168.0.1 getcrus -lccrevb
Check the Backend Bus speeds
naviseccli -scope 0 -user username -password password –address 192.168.0.1 backendbus –get –speeds 0

naviseccli -scope 0 -user username -password password -address 192.168.0.1 getcache
