Logical vs physical I/O's in Solaris? 1

[mgiven]

Are there any commands that can be used to figure out how many physical I/O's are taking place compared to the number of logical I/O's?

hi, the diferences between i/o physical (hard disk) and logical names are:
try this commands
#sysdef
or
#prtconf | grep -v not

example:
# prtconf | grep -v not
System Configuration: Sun Microsystems sun4d
Memory size: 256 Megabytes

Presumably you want to establish how much I/O is being satisfied by the filesystem buffer cache?

Try using sar -b 1 1000? Annihilannic.
