Hi, a bit OT but kinda relevant.=0A= =0A= We have an app which runs on
9.2.0.4 HP = and SUN and =0A= it is very I/O intensive. What I am looking
for is some simple OS = tests to =0A= ensure that the disks have been set up
correctly (we don't usually do = the disk =0A= setup)=0A= =0A= For example
on SUN we'll typically have = 2 T3's or =0A= 3510 disk arrays set up in a
partner pair configuration with hardware = raid 5 and =0A= then raid 0
stripes across the two LUNS, plus having 4 paths from the = disk to =0A= the
server with a good cache on it.=0A= =0A= Anyhow, before we install Oracle
and = our app we =0A= want to disk the disk IO performance - does anyone
knowany good OS = tools that =0A= we can use, or some simple tests?=0A=
=0A=Don't really want to buy any tools, = plain good old =0A= OS command and
scripts would be nice :-)=0A= =0A= We want to test the I/O out before we =
install so we =0A= dont have performance trouble we need to track down and
wedon't want to = look =0A= bad either :-)=0A= =0A= Cheers for any help=0A=
=0A= Dave
