Assigning Spare(s) | ![]() |
For links and interfaces common to all Express Configuration links, please see Express Overview in ACU help. Note: If you have chosen RAID 0 as your RAID choice, you will not be able to assign a spare to your logical drives. An online spare immediately replaces a failed drive as soon as the failure occurs. The controller automatically begins rebuilding the data from the failed drive on the spare to return to a fault tolerant state. The failed drive can be replaced while the system is operating at top performance. The drawback is that the spare drive is not used while inactive and this reduces the amount of usable storage capacity. Depending on your configuration, the Online Spare option may not be available. Having chosen one of the available RAID options for your logical drives you will be asked if you would like to assign a spare(s) with the following options: No Yes |
