for instance, the script you originally quoted comes from http://www.solarisinternals.com/wiki/index.php/ZFS_Evil_Tuning_Guide#Limiting_the_ARC_Cache at the "Limiting the ARC Cache" section, and says, above it: "Current Solaris 10 Releases and Solaris Nevada Releases" (which includes you) and then talks about zfs_arc_max. *Then* it says "Earlier Solaris Releases", and talks about the structure named 'arc', which is no longer there, and any reference to it, mdb or otherwise, will fail. Is that the detail you missed?
