Hello NotStopIsilonProblems, The reason we ask you to open an SR is that we will pull a set of logs from your Isilon system prior to your upgrade and review them to make sure that you will not have any issue when doing the upgrade.  We also will pull a set of logs after the upgrade to ensure that everything was upgraded correctly.   If you don’t want to create an SR, then I would make sure to gather a set of logs prior to doing the upgrade.
Hello all I am wondering if someone can advise... I have been asked to look at upgrading our Isilon from 8.2.2.0 to 9.1.0.0. The documents show that it is best to log an SR  Question to the group, thanks
Upgrade 8.2.2.0 to 9.1.0.0
