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!
