HP XP7 Storage - Manual (Page 141)

If you delete WWN from the PFC targets by using the PFC group name, the PFC setting and the
group under the specified port are deleted. If the same PFC group name is set to another port,
only the PFC setting of the specified port is deleted.
Resource group function and restrictions when running Performance Control
When you use the resource group function, the range of operation is limited per port of resource
group by Performance Control. The threshold value, the PFC name, and the PFC group name,
which are managed in the entire system, are common among the resource groups.
When you perform Performance Control operations using the resource group function, share the
threshold value that the storage administrator determines among users of resource groups. Determine
rules for PFC names and PFC group names including port names to avoid redundant names between
ports.
Virtual storage machine operations
Creating host groups in a virtual storage machine
To create host groups in a virtual storage machine and to assign virtualized LDEV to LU, perform
the following provisioning operations.
Executed command Description Operation overview Step
raidcom add resource -resource_name
<resource group name> -port
<port#>-<HG#> Reserve ports and host group IDs to the
resource groups in the virtual storage
machine. Be sure to execute the
command before creating host groups. Reserving host group IDs 1
raidcom add host_grp -port
<port>-<HG#> -host_grp_name <host
group name> Create host groups by specifying the
reserved port and host group ID to the
resource group. Creating host groups 2
raidcom modify host_grp -port <port>
[<host group name>] - host_mode < host Specify the host mode to the created host
group. Also, specify the host mode
options if necessary. Specifying the host mode
and host mode options 3

option> … ]
raidcom add hba_wwn -port <port>
[<host group name>] -hba_wwn <WWN
strings> Register hosts to the host group. Adding hosts to the host
group 4
Adding LDEVs to a virtual storage machine
To add LDEVs to a virtual storage machine and to use LDEVs from hosts, perform the following
provisioning operations.
Executed command Description Operation overview Step
raidcom unmap resource -ldev_id <ldev#>
-virtual_ldev_id <ldev#> Specify an LDEV ID to delete the virtual
LDEV ID set by default. By default, the Delete the virtual LDEV
ID set by default 1
virtual LDEV ID is the same as the real
LDEV ID.
raidcom add resource -resource_name
<resource group name> -ldev_id <ldev#> Add the LDEV of which the virtual LDEV
ID was deleted to the resource group in
the virtual storage machine. Add the LDEV to the
resource group 2
