NOTE: Any change to the username and password information used to generate
the InServ Storage Server authentication information requires a local
authentication update using the following command:
ProvCfg InServ –sys <sysname> -user <username> -pass
<password>
NOTE: To add an additional InServ Storage Server configuration, use the
following command:
ProvCfg InServ –sys <sysname> -user <username> -pass
<password>
Make sure that the Windows system is connected to the new InServ Storage
Server via an FC/ISCSI port prior to the addition.
NOTE: Any change to the Log or InServ option using the ProvCfg.exe utility
requires that both the Volume Shadow Copy Service and the 3PAR VSS Provider
service be restarted.
