crsctl? srvctl? my mistake?

From Clusterware Administration and Deployment Guide

================================================

crsctl modify resource

Use the crsctl modify resource command to modify the attributes of a particular resource in Oracle Clusterware.

Syntax

crsctl modify resource resource_name -attr "attribute_name=attribute_value" [-i] [-f] [-delete] 

============================================

Okey-dokey ...

oracle:+ASM$ crsctl modify resource ora.DATA.dg -attr AUTO_START=restore -iCRS-4995:  The command 'Modify  resource' is invalid in crsctl. Use srvctl for this command.

And researching 'srvctl' for same proved a dead-end.

And just to add icing on the cake:

oracle:+ASM$ crsctl modify resource -hUsage:  crsctl modify resource <resName> -attr "<specification>[,...]" [-f] [-delete] [-i]
