----- Original Message ----- The setup flow is: 1. connectStorageServer (this connects the host to storage. i.e. either performs a 'mount' or iscaiadm command) 2. createStorageDomain (only required once) 3. createStoragePool (only required once) Once you have the pool, on all hosts you perform: 1. connectStorageServer 2. connectStoragePool And on one (and only one) of the hosts: 1. spmStart
