If you are going to just create a new partition/file system anyways, you don't have to extent, you could just create a new logical disk, it would show as da1. To do that: hpacucli ctrl sl=0 array A create type=ld raid=1 That will use whatever space is available in array A (if the current status is that the two new drives have been added to array A). Of in case the drives are still seperate you can create an array B. -- Regards, Ulf. --------------------------------------------------------------------- Ulf Zimmermann, 1525 Pacific Ave., Alameda, CA-94501, #: 510-865-0204 You can find my resume at: http://www.Alameda.net/~ulf/resume.html
