Here is a warning for people that might be doing a head upgrade from a 3050 to a 3170 (and possibly other heads). The documentation states that you need to bring the 3050 heads up-to the same software level as the 3170 heads. This may very well be the case but they fail to mention that the 3170 uses a different build of OnTap and that you need to upgrade OnTap on the 3170&#39;s immediately after the upgrade with the build for the 3170&#39;s. <br>
<br>So right now we are running 3170&#39;s with a build of OnTap 7.2.6.1 built for the 3050&#39;s and getting these errors in syslog:<br><br>na1-u-e0a [na1-u: mgr.stack.openFail:warning]: Unable to open function name/address mapping file /etc/boot/mapfile_7.2.6.1.2O: No such file or directory<br>
<br>Netapp Supports response is: &quot;Upgrade or you&#39;ll probably get Kernel Panics.&quot; and &quot;We&#39;ll try to update the documentation.&quot;  Needless to say I&#39;m not impressed.<br clear="all"><br>-- <br>Romeo Theriault<br>
