# raidcom add pfc_wwn -port CL4-E -pfc_name
ORA_NODE0_CTL_0 -hba_wwn 210000e0,8b0256f8
Set the PFC name (ORA_NODE1_CTL_1) for the WWN (210000e08b039c15).
# raidcom add pfc_wwn -port CL4-E -pfc_name
ORA_NODE1_CTL_1 -hba_wwn 210000e0,8b039c15
PFC names are managed uniquely in the entire system.
Grouping multiple host bus adapters into one group
You can group the host bus adapters into PFC groups, and then use the PFC groups to change the
priorities of multiple host bus adapters at the same time. You can also set the same upper limit
value for all host bus adapters in a PFC group at the same time.
Examples of setting the PFC group:
Set the PFC name (ORA_NODE0_CTL_0) for the PFC gropup name (WWN_GRP_LINUX0).
# raidcom add pfc_group -port CL4-E -pfc_group WWN_GRP_LINUX0 ORA_NODE0_CTL_0
Set the WWN (210000e08b039c15) for the PFC gropup name (WWN_GRP_LINUX1).
# raidcom add pfc_group -port CL4-E -pfc_group
WWN_GRP_LINUX1 -hba_wwn 210000e0,8b039c15
PFC group names are managed uniquely in the entire system.
Checking the traffic of the prioritized WWN and the non-prioritized WWN
You can use the monitoring function to check whether the performance of the prioritized WWN
can be secured by setting the upper limit. Example of acquiring the monitoring information:
Acquires the monitoring information by specifying the WWN (210000e08b039c15).
# raidcom monitor pfc_wwn -hba_wwn 210000e0,8b039c15
PORT PFC_MD IOps KBps Serial#
CL4-E WWN 5000 5000000 63528
Stopping performance control of server by using PFC function
To stop controlling the performance of the server by using the PFC function, delete the PFC name
from the PFC targets.
Example of deleting from the PFC targets:
Delete the PFC name ("ORA_NODE0_CTL_0") from the PFC targets.
# raidcom delete pfc_wwn -port CL4-E -pfc_name ORA_NODE0_CTL_0
Caution about exclusive access control with Remote Web Console
Performance Control settings are exclusive for RAID Manager operations and Remote Web Console
operations:
•
If you set Performance Control using RAID Manager, you cannot set Performance Control from
Remote Web Console. You need to delete all Performance Control settings made using RAID
Manager, and then use Performance Control on Remote Web Console to make the Performance
Control settings.
•
If you set Performance Control using Remote Web Console, you cannot set Performance Control
using RAID Manager. You need to delete all Performance Control settings made using Remote
Web Console, and then use Performance Control from RAID Manager to make the Performance
Control settings.
Deleting WWN from the PFC targets with PFC name or PFC group name
If you delete WWN from the PFC targets by using the PFC name, the PFC setting and PFC name
under the specified port are deleted. If the same PFC name is set to another port, only the PFC
setting of the specified port is deleted.
