Failed Disk Problem

natrian_maxwell — Thu, 05 Jun 2025 07:09:39 GMT

Hello,

( PLease excuse any typos....some of my keys are sticking.)

I am currently running Netapp Simulator 7.3.2. Last night before I went to bed I decided to zero all of my spare disks. Well, during the course of my night, my simulator went to sleep. This caused 6 disks to go into a failed status.

How can I recover these disks and brink them ou of a broken status?

Example:

Broken disks

RAID Disk    Device    HA SHELF BAY CHAN Pool Type RPM Used (MB/blks)    Phys (MB/blks)

You can try the following to unfail your disks.

"priv set diag" { swicth to diag mode }

"disk unfail -s <disk_name>" { -s is to unfail your disks and to make them spare}

e.g. "disk unfail -s v4.29"

Let me know how it worked out.

warm regards,

Perfect thanks. Is there a way I can do mulitple at once? Or do you normally have to do them one at a time?

I think the command takes only one disk name at a time. I tired with 2 disk names and got the error as:

f2050-184-104*> disk unfail 0c.00.2 0c.00.3
disk unfail: Has extra arguments
usage: disk unfail [-s (make disk spare)] <disk_name>
f2050-184-104*>

If you have too many disk you can write a small script to do this.

Thanks.

warm regards,

Abhishek
