Two hours later, wondering why the activity light is constantly flashing, I open the Windows Megaraid manager, and see.
See detailed information in “ MegaRAID SAS Software User Guide, Rev P” chapter “4.2 Starting the WebBIOS Configuration Utility” and “4.9 Viewing and Expanding a Virtual Drive” page 131, 158 for further details.Īlways create a backup prior to Hardware / Software changes. The MegaRAID mananger reports everything is OK and the array is 'Optimal'. You cannot mix SAS with SATA drives in the same VD / RAID Volume. As long as they support HotSwap and have the same bus like SAS or SATA. Also adding physical disks while running to a VD is working well. You will have to create a backup, delete the array, create a new RAID and restore your backup to the new virtual drive. Re: Online Expand RAID 5 Array with MegaRAID Storage Manager Its no problem to expand online while OS is running. If you have more than 1 virtual drive, then you cannot enlarge your array. Please keep in mind, there should only be “1 virtual drive” on the array.
How to expand an existing LSI raid array using MegaCli. NOTE: Capacity expansion is only possible on RAID 0, 1, 5 and 6. Expand your knowledge of hardware, software and supercomputing. A drive group with a boot span and a data span also cannot be modified. Delete the array and create a new array with all the drives, Now restore your backup to the array. If you want to expand RAID 00, 10, 50 or 60, you will have to first create a backup of your system. You can expand some RAID arrays by adding drives to the existing array as follows:Įxpanding RAID 0 (Using 2x drives), you require a minimum of 1x drive.Įxpanding RAID 1 (Using 2x drives), you require at minimum of 2x drives.Įxpanding RAID 00 (Using 4x drives), RAID cannot be expanded.Įxpanding RAID 10 (Using 4x drives), RAID cannot be expanded.Įxpanding RAID 5 (Using 3x Drives), you require a minimum of 1x drive.Įxpanding RAID 6 (Using 3x Drives), you require a minimum of 1x drive.Įxpanding RAID 50 (Using 6x Drives), RAID cannot be expanded.Įxpanding RAID 60 (Using 8x Drives), RAID cannot be expanded.
