Areca Raid Commands

1. Command to check the status of raid.

CLI> rsf info
# Name Disks TotalCap FreeCap DiskChannels State
===============================================================================
1 Raid Set # 00 4 4000.0GB 0.0GB 12×4 Degraded
===============================================================================

Here we could see that the server has 4 drives with a total capacity of 4TB and the raid is degraded.

2. Command to check the status of disks.

CLI> disk info
# Ch# ModelName Capacity Usage
===============================================================================
1 1 WDC WD1002FBYS-02A6B0 1000.2GB Raid Set # 00
2 2 WDC WD1002FBYS-02A6B0 1000.2GB Raid Set # 00
3 3 WDC WD1002FBYS-02A6B0 1000.2GB Failed
4 4 WDC WD1002FBYS-02A6B0 1000.2GB Raid Set # 00
===============================================================================

The above information shows that the drive connected to channel/port 3 is degraded.

3. Command to check the disk information

CLI> disk info drv=3
Drive Information
===============================================================
IDE Channel : 3
Model Name : WDC WD1002FBYS-02A6B0
Serial Number : WD-WMATV5700033
Firmware Rev. : 03.00C06
Disk Capacity : 1000.2GB
Device State : NORMAL
Timeout Count : 0
Media Error Count : 55
Device Temperature : 26 C
SMART Read Error Rate : 200(51)
SMART Spinup Time : 253(21)
SMART Reallocation Count : 200(140)
SMART Seek Error Rate : 200(0)
SMART Spinup Retries : 100(0)
SMART Calibration Retries : 100(0)
===============================================================

This command will show us the serial number of the hard disk so that we can confirm before replacing the degraded drive.

4. Checking the event log

CLI> event info
Date-Time Device Event Type Elapsed Time Errors
===============================================================================
2015-01-01 08:02:48 IDE Channel #03 Device Failed
2015-01-01 08:02:48 Raid Set # 00 RaidSet Degraded
2015-01-01 08:02:48 ARC-1110-VOL#00 Volume Degraded
2014-12-18 03:46:09 ARC-1110-VOL#00 Complete Rebuild 041:54:30
2014-12-16 09:51:39 ARC-1110-VOL#00 Start Rebuilding

===============================================================================

Shows when the raid is degraded, whether any rebuild is in progress, etc

5. Starting manual rebuild

If the raid does not start rebuild automatically after drive replacement, it will be showing as Free.

CLI> disk info
# Ch# ModelName Capacity Usage
===============================================================================
1 1 WDC WD1002FBYS-02A6B0 1000.2GB Raid Set # 00
2 2 WDC WD1002FBYS-02A6B0 1000.2GB Raid Set # 00
3 3 WDC WD1002FBYS-02A6B0 1000.2GB Free
4 4 WDC WD1002FBYS-02A6B0 1000.2GB Raid Set # 00
===============================================================================

In this case we need to manually add the drive to array and start rebuild.

CLI> rsf createhs drv=3

6. Password errors

If any command is showing password required error like below,

CLI> rsf createhs drv=3
GuiErrMsg<0x08>: Password Required

we can simply set a one time password and can execute the command.

CLI> set password=0000
GuiErrMsg<0x00>: Success.

CLI> rsf createhs drv=3
GuiErrMsg<0x00>: Success.

7. Changing disk priority to speedup the raid rebuild

CLI> sys changept p=3
GuiErrMsg<0x00>: Success.

use the above command to change priority of disk in port 3 to speed up raid rebuild.
