I am running Solaris U4 x86_64.

Seems that something is changed regarding mdb:

# mdb -k
Loading modules: [ unix krtld genunix specfs dtrace cpu.AuthenticAMD.15 uppc
pcplusmp ufs ip hook neti sctp arp usba fctl nca lofs zfs random nfs sppp crypto
ptm ]

    hash_elements_max = 0x40fac
    hash_collisions = 0x138464
    hash_chains = 0x92c7

How can I set/view arc.c_max now?
