Using LED indications, your LaCie professional DAS alerts you if a hard drive is failing or has failed. See the user manual for your LaCie product to review the LED indications. LaCie RAID Manager also senses when a hard drive is at risk and updates the Event Log accordingly. Additionally, LaCie RAID Manager has built-in notifications that will you send you email alerts when a disk fails or the enclosure experiences high temperatures (see Manage the Array and Virtual Disk).
With the exception of RAID 6, the loss of a single hard drive in the array will degrade the RAID and prevent it from protecting your data. To help you prepare for the potential of hard drive failure, LaCie RAID Manager gives you two critical options:
LaCie RAID Manager will automatically rebuild a degraded array when auto-rebuild is enabled. The rebuild operation will start immediately if a spare drive is available in the enclosure (see below). If you have not assigned a spare drive, auto-rebuild will begin once the failed hard drive is hot-swapped with a replacement. See your LaCie product’s user manual for instructions on how to hot-swap a hard drive.
LaCie RAID Manager offers two options for assigning a spare hard drive:
Only an unconfigured physical disk can be assigned as a spare drive. A physical disk which is either fully or partially configured cannot be used as a spare drive.
The hard drive’s Property tab confirms that it has been assigned as a dedicated spare drive.
LaCie RAID Manager confirms the change by updating the Status of the physical disk in the Property tab.
