The server has two logical drives. The second logical drive consists of two disks and mirror each other so its setup RAID 1.<BR />My problem is that both disks are showing a "Red light" to indicate a fault. I am aware this means there is going to some data loss. I have reseated both disks and the "Red Light" has cleared.<BR /><BR />When I reboot the HP Proliant DL380 server the system automatically ran "fsck" to fix bad block errors in the mirror set.<BR /><BR />I have a good backup of the file system so I can restore the file system.<BR /><BR />I want to know if I did replace the two physical disks in the mirror, would I need the Smartstart CD to recreate the logical drve as mirror (Raid 1) and if so how?<BR /><BR />Thank you Wed, 08 Dec 2010 16:08:04 GMT https://community.hpe.com/t5/operating-system-linux/recreating-a-logical-drive-with-smartstart-cd/m-p/4723686#M43004 Danesh Qureshi 2010-12-08T16:08:04Z https://community.hpe.com/t5/operating-system-linux/recreating-a-logical-drive-with-smartstart-cd/m-p/4723687#M43005 You can do so via the BIOS/Smart Array Controller's Firmware OR via the OS's hpacutil utility.<BR /><BR />It should be very straightforwardy either way.<BR /><BR /> Wed, 08 Dec 2010 17:40:44 GMT https://community.hpe.com/t5/operating-system-linux/recreating-a-logical-drive-with-smartstart-cd/m-p/4723687#M43005 Alzhy 2010-12-08T17:40:44Z
