Changing from active/active to active/passive in 7-Mode

Hello,

 

I have a Netapp FAS2240-4 with Release 8.2.4P4 7-Mode. It has two controller boards, one disk shelf an a total of 48 disk (24x2TB in the FAS and 24x1TB in the shelf). It is out of support, so I think I can not upgrade Ontap. I used to have the disks configured like this:

Now I would like to use a configuration like this:

I bootet into maintenance mode and changed the owner of all disks to Node 1. But now Node 2 does not boot, because it does not have any disks. The status of the aggregates is like this:

aggr status -v
Aggr State Status Options
aggr0 online raid_dp, aggr root, diskroot, nosnap=off, raidtype=raid_dp,
64-bit raidsize=11, ignore_inconsistent=off,
snapmirrored=off, resyncsnaptime=60,
fs_size_fixed=off, lost_write_protect=on,
ha_policy=cfo, hybrid_enabled=off,
percent_snapshot_space=0%,
free_space_realloc=off

Volumes: vol0

Plex /aggr0/plex0: online, normal, active
RAID group /aggr0/plex0/rg0: normal, block checksums
RAID group /aggr0/plex0/rg1: normal, block checksums

aggr1 offline raid_dp, aggr diskroot, raidtype=raid_dp, raidsize=11,
foreign resyncsnaptime=60, lost_write_protect=off,
64-bit ha_policy=cfo, hybrid_enabled=off,
percent_snapshot_space=0%
Volumes: <none>

Plex /aggr1/plex0: online, normal, active
RAID group /aggr1/plex0/rg0: normal, block checksums
RAID group /aggr1/plex0/rg1: normal, block checksums

And the volume:

vol status -v
Volume State Status Options
vol0 online raid_dp, flex root, diskroot, nosnap=off, nosnapdir=off,
64-bit minra=off, no_atime_update=off, nvfail=off,
ignore_inconsistent=off, snapmirrored=off,
create_ucode=on, convert_ucode=on,
maxdirsize=45875, schedsnapname=ordinal,
fs_size_fixed=off, guarantee=volume,
svo_enable=off, svo_checksum=off,
svo_allow_rman=off, svo_reject_errors=off,
no_i2p=off, fractional_reserve=100, extent=off,
try_first=volume_grow, read_realloc=off,
snapshot_clone_dependency=off,
dlog_hole_reserve=off, nbu_archival_snap=off
Volume UUID: 370ddab1-6719-11e3-8d9a-123478563412
Containing aggregate: 'aggr0'

Plex /aggr0/plex0: online, normal, active
RAID group /aggr0/plex0/rg0: normal, block checksums
RAID group /aggr0/plex0/rg1: normal, block checksums

Snapshot autodelete settings for vol0:
state=off
commitment=try
trigger=volume
target_free_space=20%
delete_order=oldest_first
defer_delete=user_created
prefix=(not specified)
destroy_list=none
Volume autosize settings:
mode=off
Hybrid Cache:

 

What steps am I missing to setup the configuration in the picture above? If possible, I do not want to start from scratch.

 

Thank you,

Re: Changing from active/active to active/passive in 7-Mode

you don't need to do it that way.  You could have easily torn down the system, and 7-mode is software disk ownership, so once you tear down your data aggregate on the other node, you will be left with just aggr0, which will be your 3 disk raid-dp or if you choose 2 disk raid4 vol for the OS.

 

If your secondary node only had one aggregate than you need to rebuild the entire system the way you want it.  

 

The picture below looks like partition from ADP, which is cDOT only
