I can do it in bash:
_________________
#!/bin/sh
esxcfg-scsidevs -m > /tmp/esxcfg-scsidevs-m-naaID_DataStore.txt
#echo "loop through each DataStore"
echo "lunID Perennial_Reservation NaaID DataStore `uname -n`"
for DataStore in `cat /tmp/esxcfg-scsidevs-m-naaID_DataStore.txt |awk '{print $5}'`
do
#check datastore's perennial reservation setting
SD_NaaID=`grep $DataStore /tmp/esxcfg-scsidevs-m-naaID_DataStore.txt | awk '{print $1}' | cut -d: -f1`
SD_NaaID_PR=`esxcli storage core device list -d $SD_NaaID | grep "Perennially Reserved" | cut -d: -f2 | cut -d" " -f2`
lunID=`esxcfg-mpath -L | grep ${SD_NaaID}| cut -d":" -f4 | cut -d" " -f1 | sort -u | cut -c2-3`
echo "${lunID} ${SD_NaaID_PR} ${SD_NaaID} ${DataStore}"
done
naa_list=`esxcfg-mpath -l | grep "naa\." | grep "Device: " | cut -d: -f2 | sort -u`
echo "checking luns without datastores (either RDMs or new luns with no VMFS yet)..."
for naaID in `echo $naa_list` ; do
#echo "checking for RDMs with perennial reservation as false"
grep ${naaID} /tmp/esxcfg-scsidevs-m-naaID_DataStore.txt >/dev/null
RC=$?
if [ ${RC} != 0 ] ; then
lunID=`esxcfg-mpath -L | grep ${naaID}| cut -d":" -f4 | cut -d" " -f1 | sort -u | cut -c2-3`
NaaID_PR=`esxcli storage core device list -d $naaID | grep "Perennially Reserved" | cut -d: -f2 | cut -d" " -f2`
echo "${lunID} ${NaaID_PR} ${naaID} no_datastore"
fi
done

but PowerShell is the way forward for checking all hosts at once
and I'm gonna wrap it into an email and vCheck plugin too.
