SHARED PVS report SM2 reports
Monitoring information
The values correspond to those of the DEVICE report and form the sum of the values from
the individual hosts.
SM2 cannot automatically determine the percentage utilization of the disks (as in the
DEVICE report).
Each host recognizes only its own accesses to the disk. The disk is already considered
active when the I/O chaining starts, even if the system still has to wait until another host has
completed its access. This can cause a dilation of the local utilization, which depends on
the level of the local or remote loads and their distribution over time.
