Modify LU QoS Group
Overview
Change the bandwidth limit (the maximum performance limit) for the 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 LU 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.
