Anyone with a HA 4050 Cluster, can you please tell me the pros/cons of code 5.0.3 and 5.0.6? I am looking to upgrade my HA pair and have noticed CPU imbalance issues, high management plane issues with 5.0.1 on my 500, 2050's. I want to upgrade but am worried the CPU issues are not addressed/corrected with 5.0.3 and/or 5.0.6 when upgrading a 4050 cluster. Please give me your opinion.
You best reference would be The Release Notes of 5.0.6 which also mentions the addressed issues of 5.0.4 and 5.0.5.
It would be difficult to comment on Pros/Cons as they may be relative to the Network Setup.
5.0.3 definitely had a lot of log indexing issues that usually cause restarts of MGT server as well as a few other userid issues which also caused the MGT CPU to spike.
But as far as the log indexing issue goes that can cause high CPU issues, that will be fixed in 5.0.7.
5.0.6 although has a few fixes with respect to high CPU issues, waiting for 5.0.7 ( which should be out anytime in the next 12-13 days) will not be a bad option at all.
I have seen significant improvements for the mgmt plane CPU starting from 5.0.3, especially when user-id is involved.
Example: graph showed drop from 80-90% to 20-30% mgmt plane CPU when upgrading from 5.0.2 to 5.0.5. Not sure what chassis this was.
Data plane CPU remained the same
upgrade to 5.0.6
it fixes a lot of bugs.
we still have a lot of devices still on 4.1.7 due to weird issues encountered on 5.0.x
so far when running on 5.0.6, everything is looking good and we're going to move all over devices to 5.0.6
In 5.0.6, we have a bug with VPN HA ... will be fix in next 5.0.7.
There is a 5.0.6h1 and 5.0.6h2.
then waiting the 5.0.7 should be a good idea :-)
Keep in mind there is no perfect version ...
Just FYI we have a huge dataplane restart bug in 5.0.6 we're currently dealing with (TAC is involved,etc). We had to roll back to 5.0.5 because of it (and the dataplane restarts disappear after the rollback). Luckily this PA4020 is in tap mode only, so it essentially just operates as a glorified IDS right now.
