Modify LU QoS Group

This function changes the bandwidth limit (the maximum performance limit) settings of each host LUN.
• 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
