GUI item | Description |
Model | Displays the model of the hardware RAID controller. |
Driver | Displays the version of the RAID controller’s driver software. |
Firmware | Displays the version of the RAID controller’s firmware. |
Set RAID level | Select the RAID level, then click Change. For more information about RAID levels, see “About RAID levels”. |
Change (button) | Select the RAID style, then click this button to apply the RAID level. |
Re-scan (button) | Click to rebuild the RAID unit with disks that are currently a member of it, or detect newly added hard disks, and start a diagnostic check. |
List of RAID units in the array | |
Unit | Indicates the identifier of the RAID unit, such as u0. |
Type | Indicates the RAID level currently in use. For more information, see “About RAID levels”. To change the RAID level, use Set RAID level. |
Status | Indicates the status of the RAID unit. • OK: The RAID unit is operating normally. • Warning: The RAID controller is currently performing a background task (rebuilding, migrating, or initializing the RAID unit). Caution: Do not remove hard disks while this status is displayed. Removing active hard disks can cause hardware damage. • Error: The RAID unit is degraded or inoperable. Causes vary, such as when too many hard disks in the unit fail and the RAID unit no longer has the minimum number of disks required to operate in your selected RAID level. To correct such a situation, replace the failed hard disks. • No Units: No RAID units are available. Note: If both Error and Warning conditions exist, the status appears as Error. |
Size | Indicates the total disk space, in gigabytes (GB), available for the RAID unit. Available space varies by your RAID level selection. Due to some space being consumed to store data required by RAID, available storage space will not equal the sum of the capacities of hard disks in the unit. |
Ignore ECC | Click turn on to ignore the Error Correcting Code (ECC). This option is off by default. Ignoring the ECC can speed up building the RAID, but the RAID will not be as fault-tolerant. This option is not available on FortiMail-2000B/3000C models. |
List of hard disks in the array | |
ID/Port | Indicates the identifier of each hard disk visible to the RAID controller. |
Part of Unit | Indicates the RAID unit to which the hard disk belongs, if any. To be usable by the FortiMail unit, you must add the hard disk to a RAID unit. |
Status | Indicates the hardware viability of the hard disk. • OK: The hard disk is operating normally. • UNKNOWN: The viability of the hard disk is not known. Causes vary, such as the hard disk not being a member of a RAID unit. In such a case, the RAID controller does not monitor its current status. |
Size | Indicates the capacity of the hard disk, in gigabytes (GB). |
Delete (button) | Click to unmount a hard disk before swapping it. After replacing the disk, add it to a RAID unit, then click Re-scan. |
Back up data on the disk before beginning this procedure. Changing the device’s RAID level temporarily suspends all mail processing and erases all data on the hard disk. For more information on creating a backup, see “Backup and restore”. |
