CHAPTER 6MediaShield RAID Frequently Asked QuestionsDedicated Disk Questions• Can I assign a dedicated disk to a striped array/JBOD or use a free disk with stripedarray/JBOD?No, free disks and dedicated disks can be only used with a mirrored array, stripedmirrorarray, or a RAID 5 array.• Once a dedicated disk has been assigned to a RAID 1, RAID 0+1, or RAID 5 array, canI remove it?Yes, a dedicated disk can be removed from a RAID 1, RAID 0+1, or a RAID 5 array.Array Migrating Questions• Is it possible to migrate a single bootable drive to a two‐disk stripe array?That is, if I have a single drive in the system that is not RAID enabled, then decide to add asecond drive to the system, will I then be able to migrate the single bootable drive to a two‐diskstripe array?If ʺRAID Enableʺ in the BIOS RAID Config screen is not enabled when the OS isinstalled, it is not possible to convert the SATA boot drive into a multi‐disk bootableRAID array.Therefore, if you want to retain the capability to migrate a single SATA boot drive intoa multi‐disk RAID array at a future time, you must perform the OS install onto a singledisk stripe array. You can do this by following the instructions in “Creating a BootableArray” on page 21 and selecting ʺRAID Modeʺ striping and then adding just yoursingle boot disk. Then install the OS using the F6 install mechanism as described inStep 3: Install the RAID Drivers–Windows XP.Later, when you want to migrate the single disk into a multi‐disk RAID array, followthe instructions in “Migrate an Array” on page 38.• Can I delete an array while it is being migrated?Yes, but doing so will erase all the data stored on the soon to be migrated array.• Can I migrate a bootable RAID array?Yes, you can migrate to and from any supported RAID configuration.50 MediaShield User’s Guide – Version 6.0
CHAPTER 6MediaShield RAID Frequently Asked QuestionsMediaShield Application Questions• What functions can be performed using the MediaShield application?The following tasks can be performed:• View information about RAID 0, RAID 1,RAID 0+1, RAID 5 and JBOD (as well asany supported configuration if you have more than one RAID array active)• View Free Disks• Assign a dedicated disk to RAID 1, RAID 0+1, and RAID 5• Remove a dedicated disk from a RAID 1, RAID 0+1, or RAID 5 array• Rebuild a RAID 1, RAID 0+1, or RAID 5 array• View the status of the rebuilding process• Create a RAID Array• Delete a RAID Array• Migrate a RAID Array• Synchronize an ArrayNote: Not all nForce platforms provide support for all the RAID levels listed. See Table1.1, “Supported nForce Platforms and RAID Arrays” on page 2 for a matrix ofsupported RAID levels.• What is S.M.A.R.T. ?S.M.A.R.T. stands for Self‐Monitoring, Analysis, and Reporting Technology. It is a diskdrive feature that allows software to monitor degradations in disk drive specifications.Using this technology, NVIDIA MediaShield lets you monitor the health of disk drivesin a RAID array and alerts you when certain degradations indicate an impendinghardware failure, giving you time to back up data and replace the drive.NVIDIA Corporation 51
