And solaris > didn't and doesn't see any actual hw errors on the disks, does it? I had the same symptoms recently. I also thought the disk were dying but I was wrong. Suspected the RAM, no. Finally it was because I mixed raid cards on different PCI buses : 2 64bits buses (no problem with these ones) and 1 32 Bits PCI bus which caused *all* the checksum errors. Kicked ou the card on the 32 bit PCI bus and all worked fine. Hope it helps, -- Nicolas Szalay Administrateur systèmes & réseaux -- _ ASCII ribbon campaign ( ) - against HTML email X & vCards / \
