The RSH collector doesn’t correctly collect LVM information on some Linux host. As a result, there are inconsistencies in LVM reports regarding LV and PV numbers and names.
The “/sbin/lvs -o lv_name,vg_name,devices” command displays multiple PVs for some LVs if the LVM is configured that way. E.g.
LV VG Devices
root rpool /dev/sda2(0)
root rpool /dev/sda2(1920)
swap rpool /dev/sda2(768)
data_LV host_VG /dev/mapper/VPLEX.09fc(0),/dev/mapper/VPLEX.09fd(0)
Notice that LV data_LV has 2 devices/PVs listed. Currently, the LunMappingDetection.pl script used to do discovery on hosts cannot handle multiple PVs per LV.
This problem is fixed in SRM v 4.3
