Creating a resource group (P-VOL not registered to a VSM)
When GAD setup is complete, the host sees the P-VOL and S-VOL of each
pair as a single volume in a single storage system. Resource groups are
created in the secondary storage systems using the primary system's serial
number and model as virtual information, so that the P-VOL and S-VOL of
each pair share the same virtual storage machine information.
A virtual storage machine is composed of multiple resource groups that have
the same virtual information. When you create a resource group and specify
the virtual serial number and model, the resource group is registered in the
virtual storage machine. If the virtual storage machine does not already exist
in the storage system, it is created automatically when the resource group is
created. The following illustration shows the creation of a resource group
when the P-VOL is not already registered to a virtual storage machine.
Note: When specifying the serial number for VSP G1000 using CCI, add a “3”
at the beginning of the serial number. For example, for serial number 11111,
enter 311111.
