Modify LU QoS Group
This function changes the bandwidth limit (the maximum performance limit) settings of each host LUN.
For details on the parameters for this function, refer to
"A.4.6.10 Modify LU QoS Group" (page 882)
The procedure to change the bandwidth limit for host LUN is as follows:
Procedure
1
Select the LU QoS group to modify the bandwidth limit, and click [Modify LU QoS Group] in
[Action].
•
Use one LU QoS group number per 512 Host LUNs as an internal resource. When there are LU QoS groups
with a bandwidth limit other than "Unlimited" from Host LUN#512 onward, the maximum number of QoS
groups cannot be created.
•
Host-LU QoS does not support from LUN#1024 onward. Even if volumes are mapped from LUN#1024
onward, only up to 1024 LUNs (LUN#0 - LUN#1023) can be specified for the bandwidth limit.
Assigning an LU QoS group to a LUN group with Host Affinity set, the bandwidth limit can be configured for
each LUN. Refer to
"4.7.3 Set Host-LU QoS" (page 482)
for details.
