As a maintenance question, where one wants to periodically ensure that the hot spare is both available and good. How should one best : 1) Verify the hot spare is still available. 2) Verify that the hot spare is healthy? -- With our best regards, //Maurice W. Hilarius Telephone: 01-780-456-9771/ /Hard Data Ltd.
