daily scsi defect status...

[John-Mark Gurney]

I thought someone a while back had added scsi defect monitoring to our
periodic config, but upon upgrading one of my boxes, I found out that
no one had...

I no longer have any scsi disks, but could someone try out the attached
daily script?  Of course, you'll want to add the following lines to your
/etc/periodic.conf:
daily_status_scsi_disks_enable="YES"

In the normal case, you should just see:
SCSI Disk defect status:
da0:
da1:

and the files for these defects are in /var/backups if you want to
see the exact defects on your disks...

If the code works fine, I'll cordinate with the correct people to
commit it.

Thanks for testting it out.
