RAID Software User s Guide Hotspares can be set as global or dedicated A global hot spare automatically comes online to replace the first drive to fail on any array or disk group on the controller A dedicated hot spare is assigned to a specific array or disk group and only comes online to rebuild this specific failed array or disk group A hot spare only comes online if it is the same size or larger than the failing drive see drive coercion below and if a drive has been marked as failed If a drive is removed and marked as failed within a virtual drive the hot spare automatically comes online However there must be disk activity I O to the drive in order for a missing drive to be marked as failed Drive coercion refers to the ability of the controller to recognize the size of the physical drives connected and then force the larger drives to use only the amount of space available on the smallest drive Drive coercion allows an option to map out a reserved space to compensate for slightly smaller drive sizes that may be added later The default is set to 1 GB The coercion algorithm options are None No coercion of size 128 MB The software rounds the drive capacity down to the next 128 MB boundary and then up to the nearest 10 MB until the coerced capacity is larger than the actual drive size It is then reduced by 10 MB 1 GB The software rounds the drive capacity down to the nearest I GB boundary and then down by 1

43. Spare Drives Data availability without downtime is essential for many types of data processing and storage systems Businesses want to avoid the financial costs and customer frustration associated with failed servers RAID helps you maintain data availability and avoid downtime for the servers that provide that data RAID offers several features such as spare drives and rebuilds that you can use to fix any physical disk problems while keeping the servers running and data available The following subsections describe these features You can use spare drives to replace failed or defective drives in an array A replacement drive must be at least as large as the drive it replaces Spare drives include hot swaps hot spares and cold swaps A hot swap is the manual substitution of a replacement unit in a disk subsystem for a defective one where the substitution can be performed while the subsystem is running performing its normal functions In order for the functionality to work the backplane and enclosure must support hot swap Hot spare drives are physical drives that power up along with the RAID drives and operate in a standby state If a physical disk used in a RAID virtual disk fails a hot spare automatically takes its place and the data on the failed drive is rebuilt on the hot spare Hot spares can be used for RAID levels 1 IME 5 6 10 50 and 60 Note lfa rebuild to a hot spare fails for any reason the hot spare drive will be mark

ID 0 is not redundant there is no hot spare value If a hot spare drive is not an option then it is possible to perform a hot or cold swap of the failed drive to provide the new drive for rebuild after the drive failure A swap is the manual substitution of a replacement drive in a disk subsystem If a swap is performed while the system is running it is a hot swap A hot swap can only be performed if the backplane and enclosure support it If the system does not support hot swap drives then the system must be powered down before the drive swap occurs This is a cold swap In all cases hot spare hot swap or cold swap the replacement drive must be at least as large as the drive it replaces In all three cases the failed drive is removed from the array If using a hot spare then the failed drive can remain in the system When a hot spare is available and an automatic rebuild starts the failed drive may be automatically removed from the array before the utilities detect the failure Only the event logs show what happened If the system is shut down during the rebuild all rebuilds should automatically restart on reboot Note If running a sliced configuration RAID 0 RAID 5 and RAID 6 on the same set of physical drives then the rebuild of the spare will not occur until the RAID 0 array is deleted On Intel RAID Controller RS2WC080 and RS2WC040 if Virtual Drive is in degrade mode due to failed physical drive auto rebuild is not suppor

ID Recovery feature also known as Snapshot offers a simplified way to recover data and provides automatic protection for the boot volume You can use MegaRAID Recovery to take a snapshot of a volume and to restore a volume or file Snapshot functionality allows users to capture data changes to the volume If data is deleted accidentally or maliciously you can restore the data from view or roll back to a snapshot at a previous Point in Time PiT You can make up to 8 snapshots of Point in Times for each volume You can either restore files or roll back applications to a previous point in time Recovers lost data from disk in minutes minimizing the downtime experienced by users and eliminating the lengthy process of restoring data from tape Allows isolation of a server s boot volume to a separate virtual drive by enabling the Auto Snapshot feature users are guaranteed that bootable snapshots exist in case corruption of operating system occurs Note MegaRAID Recovery Snapshots are not a substitute for a tested backup strategy When Recovery Snapshot is enabled changes to the selected volume are tracked When a roll back to a snapshot at a previous Point in Time PiT is done you are undoing changes to the volume that caused corruption or a file deletion The first snapshot does not create a full volume backup Recovery Snapshot is equivalent to Microsoft System Restore with additional features and capabilities Detailed Configura
