Flare code warning, 04.30.000.5.012 and 04.30.000.5.011
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.
