The chvg command with the -t option is used to reduce the maximum number of physical volumes (PVs) allowed in a volume group (VG). This is necessary when the number of PVs in a VG exceeds the maximum allowed. Reference: IBM AIX v7 Administration Specialty Study Guide (section 10.3.3, pp. 641-642).

Thechvg -tcommand in AIX is used to change the factor by which the maximum number of physical partitions (PPs) per physical volume (PV) is increased. When this command is used to increase the maximum PPs, it allows more physical partitions on a physical volume, but it reduces the maximum number of physical volumes that can be included in the volume group. This is necessary when the required PPs exceed the current limit due to large disk sizes or large numbers of partitions.References: IBM AIX Documentation - chvg
