The two examples of items you're asking about below are more volume centric than SVM centric per se. Anyway, you can output data across the whole cluster with commands like the following:
cluster::> volume efficiency show -vserver * -fields schedule
(Display all the dedupe schedules)
cluster::> sis policy show
(Display all the deduple policies)
cluster::> volume snapshot policy show -vserver *
(Display all the snapshot policies associated with each SVM)
cluster::> volume show -vserver * -fields snapshot-policy
(Display the snapshot policy associated with each volume)
WIth the rows 0 option set at the beginning, these format pretty well into a "text-to-columns" kind of importable format for Excel.
That said, I'm not aware of anything like the old config-advisor in DFM (or now in the new MyASUP tool) that would just let you "show me all the differences between my SVMs" - and since a lot of information is going to be volume centric anyway, it's going to be a little tough for any tool to pick out just what is different for the things you set at a SVM level.
Definitely in the category of hard-to-read is the output from the following:
cluster::>vserver show -vserver * -fields vserver,type,subtype,uuid,rootvolume,aggregate,nisdomain,rootvolume-security-style,ldap-client,language,snapshot-policy,comment,quota-policy,aggr-list,max-volumes,admin-state,operational-state,operational-state-stopped-reason,allowed-protocols,disallowed-protocols,is-repository,qos-policy-group,caching-policy,config-lock,ipspace,foreground
Doesn't have the specific items you list below, but does have a lot of the basics on each SVM listed in a nice column-formatted output.
Hope that helps,
