I had a Snap Server 2000 with 2x250GB arduous drives in it. The drives have been set to mirror for knowledge redundancy. Fortunately, I did as after about 18 months, one of many drives failed! Had this been setup as a stripe, all the info would have been misplaced. (I do know all about drive failure so the SNAP Server was additionally backed up from one other workstation as one other layer of redundancy.)
The drive that failed was the boot drive, however the SNAP Server switched proper over to the mirror drive and saved on operating. Fixing the SNAP Server 2200 was much more bother than I believed it will be! I assumed I might have the ability to merely swap the unhealthy drive with one other good drive, and it will rebuild all by itself. I used to be improper! I did lastly get it to working however it took some tome and analysis. The steps under have been what I needed to do to get the SNAP Server again up and operating.
The very first thing I needed to do was to find out which drive was unhealthy. I merely took the SNAP Server aside and disconnected every of the drives till the server wouldnt boot. It might have been a lot simpler to enter the web interface to see the disk standing to find out the failed drive. However after I did this, it mentioned that the boot disk, disk 0 had failed. Wanting on the {hardware} gave no indication which was the boot drive and which was the secondary drive! Because it seems, disk 0, or the boot drive is the highest drive. The secondary drive is on the underside.
I eliminated the unhealthy drive and ordered a precise reproduction of the failed drive. It will be important for a mirror to have a precise reproduction of the great drive. I ordered two of the drives straight away in case the great drive fails within the close to future.
I put the brand new drive within the SNAP Server (each drives must be configured as Grasp IDE drives) and I powered it on. The SNAP Server wouldn’t boot! It might enter reset mode (the power and disk lights would blink in tandem) and go no additional. I chilly not even talk with the server. So I referred to as Adaptec tech help (Adaptec bought SNAP.) they usually informed me there was no approach to do what I needed to do and that the server wanted to be returned for repair! How unfaithful! What I found from analysis is that the SNAP Server will boot off the mirrored drive (backside drive) however it will not rebuild a brand new drive from there! The SNAP Server should boot and run the working system from the grasp drive (disk 0 or the highest drive) with a view to rebuild a mirror.
I put the brand new drive within the backside slot and moved the great, authentic backside drive to the highest slot. I powered on the SNAP Server. Solely then did I eradicate the blinking light, reset mode. I accessed the SNAP Server through the web interface and seemed on the Disk Standing web page. It confirmed that I had two drives! My boot drive as logical disk 10000 and the brand new clean disk was logical disk 10010.
As soon as I had the backup mirror drive (the one with all my knowledge) on high (it was now drive 10000), the Snap booted up. Now it was time to rebuild the mirror. Nevertheless, disk standing confirmed a cracked mirror. I couldn’t rebuild the mirror as a result of it saw the brand new drive as a separate drive and was nonetheless on the lookout for the remainder of the mirror. So I needed to break the mirror by making each drives particular person drives, then re-establish the mirror. This began the rebuild with no lack of knowledge 저혈압치료제 블박쇼츠.
The precise steps are under.
1. Put good drive in high slot of SNAP.
2. Put new drive in backside drive of SNAP. Activate SNAP.
3. Reformat the brand new drive by executing the next command from the ipaddress/config/debug web web page. (For instance [http://192.168.1.1/config/debug]) Notice: DD is the variety of the issue arduous disk. co de format 100DD /reinit In my case it was co de format 10010 /reinit (After reboot, this configures 100DD as a SINGLE drive and FORMATS it.)
4. Reboot the Snap server.
5. Now break the mirror with this command co de config particular person 10000 10010
6. Reboot.
7. After the orphaned disk is formatted and the drives are transformed to particular person drives, execute this command from the ipaddress/config/debug web page. (For instance [http://192.168.1.1/config/debug]) co de config mirror 100SS 100DD SS is the supply disk, DD is the vacation spot disk. In my case the command was co de config mirror 10000 10010 (This step mirrors the drive with knowledge to the drive with out knowledge.)
5. Reboot the Snap. If the whole lot works in accordance with plan, the View Disk Standing web page ought to report Rebuilding backup disk when it comes again online.
As soon as I went by way of this whole course of, the mirror was re-established and all the info was rebuilt. The entire 250GB drive took round 5-6 hours to rebuild. However now I’ve a SNAP Server 2200 with a brand new drive. The server is mirrored so I might be relaxation assured that my knowledge is secure.
