how to reassign disks

[CCOLEMAN_]

Hello,

I have added a DS4243 with 24 1TB drives to my FAS2040.

It looks like the disks on my new shelf have already been assigned before. Anytime I try to do a disk_removeownership or disk_unassign it says this can only be done in maintenance mode?

How can I unassign and reassign the disks with out taking the filer down? (I only have one controller)

Thanks!

Hello,

Try this:

Identify the actual sysid owner:

> disk show

Remove the ownership using disk assign:

> disk assign <disk_id> -o unowned -s <sysid>

Hey Rodrigo,

When I do a "disk show" it only shows me the internal disks in my 2040 with.

But heres what I get anyway,

netapp01*> Tue Dec 20 15:52:23 GMT [netapp01:diskown.RescanMessageFailed:warning                                                                                                                     ]: Could not send rescan message to unowned.

And what is the output for 'disk show -n' ?

[CCOLEMAN_]

netapp01> disk show -n

disk show: No disks match option -n.

netapp01>

[CCOLEMAN_]

Not sure if this helps but this is what I get for remove_ownership

netapp01*> disk remove_ownership 0d.01.19

disk remove_ownership: Disk 0d.01.19 is not owned by this node.

[RodrigoNascimento]

'disk show -v'

It shows all disks attached to the controllers.

-n shows unowned and -a shows all assigned....

Please, put here the 'disk show -v' output.

[RodrigoNascimento]

are you in 'priv set diag' mode?

and it is: '-o unowned', sorry for the typo mistake.

[CCOLEMAN_]

i'm in 'priv set advanced'

[RodrigoNascimento]

have you tried with '-o unowned' and it not work?

[aborzenkov]

it is

disk assign 0d.01.17 -s unowned

possibly also add "-f" for "force"

[RodrigoNascimento]

Yes, it is!

Thanks Aborzenkov... -s unowned and not -o unowned.

[fletch2007]

In 8.1.2 this works:

disk assign 6b.71 -s unowned -f

ref: https://kb.netapp.com/index?page=content&id=1010853&actp=LIST_POPULAR

cheers!

[CCOLEMAN_]

adding -f worked!!!!

Just curious, why does it require -f? that just seems a little scary

[RodrigoNascimento]

Sorry for the confusion with the options....

Good to know it solves your problem.

See you!

Hi,

"The -f option will be use if disk is not owned by the local node and may result in data corruption if the current owner of the disk is up".

I assume in your case you use the disk shelf from another system which is completely separate from the system on which you are working. 

And thanks Nascimento. Your solution also solve my problem.

Hello,

i have changing a disk on one of my controller (fas2040) but i can't assign the new disk of spare to the pool1.

i try this command "disk assign 0d.01.5 -s unowned -f". This command work without error. When i make a "disk show -n" i see the disk.

But when i try to assign the disk to the pool1 (they are 3 disks of spare on spool0) with this command: "disk assign 0d.01.5 -p 1". I have this message "disk assign: disk 0d.01.5 cannot be assigned to pool 1. Other disks on the loop are assigned to pool 0."

Do you have any ideas how i can assign this disk to the other spool ?

For information, when i make juste the command "disk assign 0d.01.5" the disk is automaticaly assigned to the spool0.

Sorry for my bad english, i hope you can understand me.

Thank you for your help.

[rmontavonsa]

i have found the command for switching spare disk to pool0 to pool1.

Firstime, you need to remove disk ownership with the command "disk remove_ownership 0d.01.5"

Now you can see the disk with the command "disk show -n"

After this, you can make the command "disk assign 0d.01.5 -p 1 -f"

But i have an other problem, i have always the message "There are not enough spare disks. /aggr0/plex0/rg0: Please add spare disks to any pool supporting block checksums with minimum " on the controller.

Do you have any ideas how i can resolve the problem ?

Thank you for your help.
