Deleting an S Series Node user account
Except for the S Series Node user account that's automatically created when you add the S Series Node to the HCP system, all other accounts can be deleted. Deleting an S Series Node user account does not delete it permanently, but rather removes the account from the HCP system. The account still exists and can be added back to the HCP system. An account can be removed only after all buckets on the account have been deleted.
Procedure
On the Buckets tab of an S Series Node, click Accounts.
Click the garbage can icon beside the account you want to delete.
In the warning message that appears, type Yes.
Click Delete.
