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>

Regards,

Nascimento

NetApp - Enjoy it!

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. Please type disk show on the consol                                                                                                                     e of unowned for it to scan the newly inserted disks.

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.

[rodrigon]

'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.

[rodrigon]

are you in 'priv set diag' mode?

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

[CCOLEMAN_]

i'm in 'priv set advanced'

[rodrigon]

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"

[rodrigon]

Yes, it is!

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

[CCOLEMAN_]

adding -f worked!!!!

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