Unassigned disk accidentally assigned to aggr0

penangmis

We have a new FAS2552 just installed as below. There is only one aggregate = aggr0.

 

How we do unassinged disk data 0b.01.14 0b from the Disk Pool  and make it become spare?

We want to have 2 spares disk instead of one.

 

aggr status -r
Aggregate aggr0 (online, mixed_raid_type, hybrid) (block checksums)
Plex /aggr0/plex0 (online, normal, active)
RAID group /aggr0/plex0/rg0 (normal, block checksums, raid_dp)

NetApp official read is: "Destroy the aggregate" Its not possible to remove ownership of that data disk and make it a spare disk.

JGPSHNTAP
Both posters are correct.

BALAJI_VENKATRAMAN

I dont think you can unassign a disk from the Raid Group or aggregate.You can only assign/unassign between conntrollers.

 

Since you say this is a new controller,cant you destroy and re-create the new aggregate?
