fc_remote_port_rolechg(9) [suse man page]

FC_REMOTE_PORT_ROLEC(9) 					  SCSI mid layer					   FC_REMOTE_PORT_ROLEC(9)

NAME

       fc_remote_port_rolechg - notifies the fc transport that the roles on a remote may have changed.

SYNOPSIS

       void fc_remote_port_rolechg(struct fc_rport * rport, u32 roles);

ARGUMENTS

       rport
	   The remote port that changed.

       roles
	   New roles for this port.

DESCRIPTION

       The LLDD calls this routine to notify the transport that the roles on a remote port may have changed. The largest effect of this is if a
       port now becomes a FCP Target, it must be allocated a scsi target id. If the port is no longer a FCP target, any scsi target id value
       assigned to it will persist in case the role changes back to include FCP Target. No changes in the scsi midlayer will be invoked if the
       role changes (in the expectation that the role will be resumed. If it doesn't normal error processing will take place).

       Should not be called from interrupt context.

NOTES

       This routine assumes no locks are held on entry.

NAME

       DROP ROLE - remove a database role

SYNOPSIS

       DROP ROLE [ IF EXISTS ] name [, ...]

DESCRIPTION

       DROP ROLE removes the specified role(s).  To drop a superuser role, you must be a superuser yourself; to drop non-superuser roles, you must
       have CREATEROLE privilege.

       A role cannot be removed if it is still referenced in any database of the cluster; an error will be raised if so. Before dropping the role,
       you must drop all the objects it owns (or reassign their ownership) and revoke any privileges the role has been granted. The REASSIGN OWNED
       [reassign_owned(7)] and DROP OWNED [drop_owned(7)] commands can be useful for this purpose.

       However, it is not necessary to remove role memberships involving the role; DROP ROLE automatically revokes any memberships of  the  target
       role in other roles, and of other roles in the target role.  The other roles are not dropped nor otherwise affected.

PARAMETERS

       IF EXISTS
	      Do not throw an error if the role does not exist. A notice is issued in this case.

       name   The name of the role to remove.

NOTES

       PostgreSQL  includes  a program dropuser [dropuser(1)] that has the same functionality as this command (in fact, it calls this command) but
       can be run from the command shell.

EXAMPLES

       To drop a role:

       DROP ROLE jonathan;

COMPATIBILITY

       The SQL standard defines DROP ROLE, but it allows only one role to be dropped at a time, and it specifies different privilege  requirements
       than PostgreSQL uses.
