Depending on the rev of DOT and if it is scsi or fc (which it looks like you have) you have loaded there is a command called "fcadmin device_map". Anywhere you see an XXX you have a drive missing. So, spun down drives will show there when broken drives will not show up on a sysconfig -r. C-

I was just reading about how a disk can drop out and the spare gets used but its not marked as failed. So I thought I would check my filer and sure enough I have a volume that has the following:

1 parity drive 6 data drives

RAID group 0

I always have a spare on a filer so I'm not sure if it has been used for a failed disk (I go to our hosting once a week to check all of the machines physically and didn't see any red lights).

How can I tell if I have a failed disk? I do a df of the volume and it shows 6x36gb disks.

Filesystem kbytes used avail capacity Mounted on /vol/vol0/ 190657844 52445200 138212644 28% /vol/vol0/ /vol/vol0/.snapshot 0 3108820 0 ---% /vol/vol0/.snapshot

My other conclusion is I screwed up when I created the volume, if so how can I turn one of the data disks into a spare?

Thanks
