Hi,
I have a faulty disk (1 out of 20) in an e450.
metastat tells me its c4t3d0s0
bash-2.03# ls -l /dev/rdsk/c4t3d0s0
lrwxrwxrwx 1 root root 46 Dec 27 2002
/dev/rdsk/c4t3d0s0 -> ../../devices/pci@6,4000/scsi@3,1/sd@3,0:a,raw
However prtconf -vp | grep $PHYSICAL_DEVICE_NAME
shows nothing, (and yes I did change sd to disk :0) )
prtdiag -v shows only 4 slots are populated - 20 are populated.
A google shows that this may be due to setenv disk-led-assoc 0 x y may
not have been run.
This, however requires a reboot, which is not satisfactory.
I've also tried dd if=/path/to/disk of=/dev/null and looking for the
lights, but the iowait on the machine renders this process unreliable,
either by trying to flash good disks or the bad one.
I've also found the serial number by iostat -En but the disks are not
sufficiently visible to locate the disk.
So I'm out of ideas, and need to replace the disk without downing the box.
Any suggestions?
Thanks,
Steve Nelson
