One of the thing I liked alot about DataOntap upgrade used to be that you can do all your prep work, copy the files, run download and then schedule a down time sometime later to finish the upgrade.
I just upgraded from 6.4.2P6 to 6.4.4R1 this Sun. I had opened a case to talk to a support engineer since the 6.4.4 upgrade document was kind of confusing. Then I told him that I was going to do the copy and download on Friday and then reboot on the scheduled down-time we had on Sun. The support engineer told me that this is no longer recommended - there are certain operations that might go to disk and the filer might panick.
I ended up taking his advice, only to find out during the maintenance down-time we had that the upgrade had problem. The 32MB PCMCIA card's service diagnostic partition did not have enough space and filer gave very misleading info to suggest that the upgrade had failed. All this when you are "on the clock"... Ugh...
Is this claim from the TSE correct? That there are some operations that might panick the filer if you do the download but did not reboot? When did this go into DataOntap? What operations will cause these problems? It is a very useful feature to have the ability to do the upgrade before-hand instead of having to do everything once the system is down and you are on the clock and everyone is breathing down your neck!
