I'm on 3.2.1 MU1 and have been running with no issues. There was a critical patch released for an issue with region moves on a TDVV (Thin Dedupe VV), but they issued a patch (P04) that fixed the issue. HP contacted me about the critical patch just after thanksgiving, and I had them install it over the weekend (Saturday and sunday after thanksgiving). No node reboot required, completely non-disruptive. That being said, since we don't have SSD, and don't use thin dedupe, there were no worries for us. I just had them do it so I didn't have to think about it. |

Well, P04 is the key to MU1. It's about dedup and moving region/chunklets of VVs in vvset setted for dedup and... data corruption ^^ So, no dedup in MU1 without P04. |

Also have one array on 3.2.1 MU1 since the release day without issue. But HP came and installed P04 immediatly when it was released. |

Did a couple of upgrades from 3.1.3 MU1 to 3.2.1 MU1 with P04 and notice a completely different issue with iSCSI. shownet -d is some issues on the iSCSI interfaces Code: Detailed Tcp stats on node 0 RtoAlgorithm: 1 RtoMin: 200 RtoMax: 120000 MaxConn: -1 ActiveOpens: 6717 PassiveOpens: 6768 AttemptFails: 33 EstabResets: 97 CurrEstab: 89 InSegs: 1111778630 OutSegs: 496370425 RetransSegs: 389274 InErrs: 0 OutRsts: 40 Detailed Tcp stats on node 1 RtoAlgorithm: 1 RtoMin: 200 RtoMax: 120000 MaxConn: -1 ActiveOpens: 39513 PassiveOpens: 77477 AttemptFails: 164 EstabResets: 41280 CurrEstab: 99 InSegs: 1105276422 OutSegs: 501448361 RetransSegs: 1165450 InErrs: 0 OutRsts: 6799 10 seconds later Code: Detailed Tcp stats on node 0 RtoAlgorithm: 1 RtoMin: 200 RtoMax: 120000 MaxConn: -1 ActiveOpens: 6717 PassiveOpens: 6768 AttemptFails: 33 EstabResets: 97 CurrEstab: 89 InSegs: 1111782268 OutSegs: 496375134 RetransSegs: 389276 InErrs: 0 OutRsts: 40 Detailed Tcp stats on node 1 RtoAlgorithm: 1 RtoMin: 200 RtoMax: 120000 MaxConn: -1 ActiveOpens: 39513 PassiveOpens: 77477 AttemptFails: 164 EstabResets: 41280 CurrEstab: 99 InSegs: 1105280815 OutSegs: 501452729 RetransSegs: 1165505 InErrs: 0 OutRsts: 6799 The above is from a 2-node 7400, also seeing similar issues on a pair of 7200's though the counts are less (much smaller configs). Just ran across the issue a few hours ago when the VM farm disconnected/reconnected half of the exported LUNs....definitely something is up. |

Fwiw we have had precisely zero issues with 3.2.1 mu1, but we run fc only (blech. The thought of iscsi makes me queasy) |
