I vaguely remember trying about a year ago to load a SMART utility from
the ports collection but it wouldn't work on drives in a RAID array.

Is there some other way to:

a) diagnose/fix the errant disk here?
b) monitor the health of disks on a Compaq controller so it doesn't get
to this point to begin with?


Hi David, apologies to Jerry for jumping in.

Compaq uses several RAID cards most are under the so-called
"SmartArray" using the ida driver. If this is yours, you can
use a utility called "idacontrol" that can monitor the array,
here's the instructions for using it. You will need usrsbin
sources installed:


) Install idacontrol


cd /usr/ports
mkdir distfiles
cd /usr/ports/distfiles
mkdir manual-build
cd manual-build
fetch ftp://ftp.jurai.net/users/winter/idacontrol.tar
cd /usr/src
tar xf /usr/ports/distfiles/manual-build/idacontrol.tar

cd /usr/src/usr.sbin/idacontrol

vi makefile change variable NOMAN to NO_MAN
make obj && make depend && make && make install

cd

idacontrol show | grep "Status"

IF status is fully up it will say:

Status: Logical drive ok

IF status is degraded it will say 1 of several other error messages.

NOTE:

The smart utility only works on SATA or ATA/IDE drives, not SCSI.
