devices to monitor via iostat
2007-12-24 23:37:00
should pay attention to. should i pay special
attentiont to the sd0 and sd1 names or monitor the
md15, md10, md11 names? this box has OS mirroring w/
DiskSuite. meaning, sd0 is the block device of the
first SCSI drive, and sd1 is the block device of the
second SCSI drive, and the md15 is the pseudo device
name for the mirror device. which stats should i pay
attention to?
a related question - i have a SAN device with a block
device of c2t61d0. how is the "sd" name presented in
iostat derived? i've looked at the actual device name
in /devices/pci at 1f,4000/.... but this doesn't seem to
match iostat's output.
any input would help.
