Using CPQONLIN
The NetWare Online Array Configuration Utility (CPQONLIN) lets you configure
your drive arrays without shutting down your server. It also indicates when a drive
attached to the array controller has failed, is undergoing expansion, or is waiting
(queued) for expansion or rebuild.
To install CPQONLIN:
1.
Load CPQRAID.HAM from the SmartStart and Support Software CD or the
Controller Support Software CD and diskettes. (Detailed instructions are given in
the README file on the CD.)
2.
Load CPQONLIN.NLM from the same source.
3.
Open CPQONLIN.NLM and follow the on-screen instructions.
