create a file
contents of file
400 804
symmir -sid xxx -f file.txt split -force -symforce (this is due to the invalid state of the devices)
symmir -sid xxx -f file.txt cancel
At this stage your relationship will be gone gone gone

Hi,
ok.. It seems that the pairing is actually split for these devices however ther relationship still exists in the symm. The only way to clear this is to establish BCV 838 to another STD of the same size/meta config.
There are a few primus articles detailing this. It should not cause you any issue.

more update:
STD meta dev 04A8 is of 34GB with below config.
04A8 --MH
04A9-- MM
04AA --MM
04AB --MT
And BCV dev 0838 is of single 8714 GB dev.

You can run the commands I have given whether the device in in a group or not. It's important that you know once this relationship is gone you have lost your ablility to do incremental establishes with device 400.
But i'm assuming you are aware of this.

You have the command wrong based on the output device 400 has LDEV name of c6t73d2s2
You need to run
symld -g venu remove dev c6t73d2s2

symld -g venu remove c6t73d2s2
If this doesn't work then you may need to delete and recreate the group
