https://community.hpe.com/t5/proliant-servers-netservers/trouble-with-smart-array-431/m-p/626654#M10677 Greetings,<BR /> <BR /> I am running a Proliant ML350 with a smart array 431 controller RAID 5 and Windows NT4 SP6.<BR /> <BR /> I am running out of disk space and recently added a drive to my array configuration. It has finished expanding the array. I now want to extend the logical drive. It will not let me and gives me error 15409 with a message of "Logical drives cannot be extended on this controller because the controller does not support logical drive extension"<BR /> <BR /> <BR /> How can I extend my drive without losing data? <BR /> <BR /> Thanks Mon, 20 Feb 2006 06:02:28 GMT PATRICK STAUB 2006-02-20T06:02:28Z https://community.hpe.com/t5/proliant-servers-netservers/trouble-with-smart-array-431/m-p/626654#M10677 Greetings,<BR /> <BR /> I am running a Proliant ML350 with a smart array 431 controller RAID 5 and Windows NT4 SP6.<BR /> <BR /> I am running out of disk space and recently added a drive to my array configuration.
