Search Term "7.1" and scope by product "Isilon" yields this and many others.
Please go check out the release notes for new features/changes/requirements/resolved and known issues.
Rolling upgrades are only available in OneFS between versions whose third or fourth digits differ. Thus, 220.127.116.11 can rolling upgrade to 18.104.22.168, or to any eventual 7.0.3 or 7.0.4 version, but as soon as the second digit increments, the versions are no longer rolling upgrade compatible.
A simultaneous upgrade from 7.0.2 to 7.1 will involve a short period of data unavailability as the nodes reboot, but the process should be quick and painless otherwise, as there is no file system upgrade or data restripe needed between those versions.
In a production environment, this is absolutely unacceptable. There's no such thing as a "short period of data unavailability" because this means that clients will fail. For some customers, that's a multi-day outage as long-running jobs fail.
ok will, 7.01 was available on support.emc.com ..any plans to make 7.1 available trough the same means ?
From what I have heard, 7.1 was announced but isn't actually available yet. Wait a couple of weeks for it to be GA...
For now the process to get 7.1 is here in KB172492 and yes I do believe there are plans to make it available through the web channel, However I do not have a timeline.
It is GA, you just have to request it.
