Yes, a hot standby configuration is definitely one way to go with LMS. This scenario is documented at http://www.cisco.com/en/US/partner/prod/collateral/netmgtsw/ps6504/ps6528/ps2425/white_paper_c07-533663.html#wp9000401 . There are also other HA solutions you can use which involve Veritas or VMWare. See http://www.cisco.com/en/US/partner/docs/net_mgmt/ciscoworks_lan_management_solution/3.2/install/guide1/hasetup.html and http://www.cisco.com/en/US/partner/docs/net_mgmt/ciscoworks_lan_management_solution/3.2/install/guide1/vmware.html for more details on those configurations.
Note: with hot standby you will need two licenses for LMS.
