To disable a service you have to be root or have a sudo, for example, i want to disable nfs:-bash-3.00# svcs | grep nfs
online 16:29:25 svc:/network/nfs/status:default
online 16:29:29 svc:/network/nfs/mapid:default
online 16:29:44 svc:/network/nfs/nlockmgr:default
online 16:32:55 svc:/network/nfs/rquota:default
online 18:49:36 svc:/network/nfs/server:default
I will disable the nfs server:
# svcadm disable network/nfs/server
