2 Replacement of a RAID harddisk[edit | edit source]
2.1 Introduction[edit | edit source]
The RAID system is setup as a “RAID 1” with one spare disk. This means that it has three disks. The first one holds all data. The second one is a excact copy of the first one and the third, spare one, will take over function of the other ones if one of them fails. With this settings two of the disk can fail and you system is still functional. However if one fails it should be replaced as soon as possible.
2.1.1 Normal condition[edit | edit source]
In front of the RAID you see something similar to this:
2.1.2 Disk failure condition[edit | edit source]
In case of a disk failure the system will beep and the LED of the affected drive will turn red. Your system will then look like this:
This means that the disk in slot two of the raid failed. There is no danger for loss of data as still another disk ran as a mirror. Only some redundacy is lost. To get it back you should insert a new disk as soon as possible (in this case the former spare disk in slot three).
How the system behaves when a disk fails depends which disk actually is affected. If a spare disk breaks this disk will show red but no further action will be triggered.
Normally however either the original or the mirrored disk will fail. In this case the affected disk will show red, the spare disk will be activated and a “rebuild” process will be started in which the data of the original disk will be mirrored to the new one. This can take about 2 hours.
Note: To quit the Alarm, press the little “MUTE” button on the frontpanel of the raid for a few seconds. The red attn alarm led will disappear after performing the following steps.
2.2 Steps to be done to replace a harddisk[edit | edit source]
- Preparation:
- Press “Power Down Button” of LINUX server and wait till all processes are stopped and the server is turned off.
- Turn off the RAID system.
- Replace harddisk:
- Make sure that the mechanical lock of the HDD tray is open.
- Press the Release button of the relevant HDD-slot an pull it to a level position.
- Grab the front bezel and pull out the HDD assembly frame.
- For installing the new one do it the other way around.
Check functionality of RAID System
- Turn the RAID on and wait till the selftest is finished.
- Turn Linux server on.
- At one of the operator stations in the IPC room:
- - Login as a user which has access to windows desktop. E.g. “ce”
- - open the Internet Explorer
- - In the address bar enter the IP-Address of the Raid-System like 10.XX.YY.179 (replace XX an YY with the Commission-Number, for example the Commission number of your line is 1498, then type in 10.14.98.179
- When the message with the RAID GUI Tools appears, press run
- In the next screen, select “Configuration” in the username box and confirm with OK
- Define new global spare:
- Physical Drives -> Maintain Spare
- -> select the slot which is not red marked
- -> press the „Next“-Button to define the slot as new global spare
- Now you get following:
You should see 3 disks. 2 displayed with green LED and one whith an yellow “+” sign. The disk with the “+” sign is the spare one. The exact location is not important. Important is that you have two disks showing green LED and one showing a yellow “+”.
Move the mouse-pointer above the top “LED“ to see following:
Check that you have “Status: Good”.
Move mouse-pointer above the “+” sign to see following:
As this is the “spare disk” you should see: “Status: Global Spare”.
Move the mouse-pointer above the bottom “LED” to see following:
Check that you have “Status: Good”.
If you don’t see it like that please contact Brückner.
