If there are disks that are already owned by a node, 4a only initializes these disks. So apparently other shelf was owned by some other node. Just remove disk ownership and reassign.

Re: Disk state showing "partner" but one 1 controller is present.

rkaushal1 — Mon, 26 Feb 2018 06:46:50 GMT

While removing disk ownership giving an error.

Netapp-GNOC002*> disk remove_ownership 0b.11.21
disk remove_ownership: Disk 0b.11.21 is not owned by this node.

Out of 3, 2 enclosures showing right status, but the middle one showing in partner stat.

Re: Disk state showing "partner" but one 1 controller is present.

aborzenkov — Mon, 26 Feb 2018 06:52:51 GMT

And if you use -f (force) option? Alternatively try "disk assign 0b.11.21 -s unowned -f"

Re: Disk state showing "partner" but one 1 controller is present.

rkaushal1 — Mon, 26 Feb 2018 07:17:14 GMT

Bad luck, its still showing the same error

Netapp-GNOC002*> disk assign 0b.11.21 -s unowned -f
disk assign: Disk is currently owned by the partner and cannot be assigned.

aborzenkov — Mon, 26 Feb 2018 07:21:39 GMT

If you really has single node, you may need to verify that filer is not configured for HA. What "cf status" says now?

Re: Disk state showing "partner" but one 1 controller is present.

3-hrs back i have disable the CF.

Re: Disk state showing "partner" but one 1 controller is present.

aborzenkov — Mon, 26 Feb 2018 07:42:53 GMT

Apparently your filer still believes it is part of HA Pair. Boot into maintenance mode and use ha-config command to check and if necessary reset HA state. Also you may need to remove partner-sysid loader variable.

rkaushal1 — Mon, 26 Feb 2018 09:19:49 GMT

After changing the ha-config from maintenance mode, i have assign disk to unowned -f and assign the disk again.

And it works. Thanks alot for your help.

But in future, if I need to enable HA. Again I have to go into maintenance mode and follow the same step. or it can be configured from the advanced mode.
