Disk Failure 880

A number of failures on a new machine with a number of disks is quite
common. If this is a two disk V880, I'd say you have a problem. If its
a 12 disk V880, I'd call Sun, swap out the disk and shrug it off.

If you look at the probability of disk failure over time, there is an
initial peak as new disks spin in, then several years of low
probability, then a ramping as they get towards the end of servicable
life.

directio shouldn't make a difference. However, I would check the
ambient temperature inside and around the machine (emphasis on
temperature stability rather than value), ensure that it not being
bumped or subject to (excess) vibration, note the humidity of the room
and check for dust.
