I would like to ask: How to back up the softraid information of win2003. Our company has a disk array. The soft raid5 used in win2003 has a lot of data. Now, because the performance of the server is too bad, you need to replace the server, but this is not necessary to re-establish. Raid, can you import the raid information directly into the new system (also win2003), thank you whether it is hard RAID or soft RAID, it is only to improve the performance or security of the disk, it is impossible to export its information again Restore to the new RAID, as you said RAID5, is a minimum of three hard drives, parity check to ensure that when only one hard drive is damaged, replace the hard drive without loss of the original data. The hardware of your server has been changed. You can only rebuild RAID5 on the new machine, the new system, and restore the data on the old machine to the new one. Personally think, for reference only to discuss this problem in two scenarios: Scene 1: The machine is equipped with 5 hard drives, disk1, disk2, disk3, disk4, disk5. Disk1 and disk2 do RAID1, and install the operating system on it. Disk3, disk4, and disk5 do RAID5, and store data files on it. It is now necessary to port RAID5 to other machines to ensure that data files are available. Install the disk array to other machines. You can't see this array in my computer. Go to Disk Management. You can see that the system thinks this array is not stored outside. You can read the relevant data by specifying a new drive letter. Scenario 2: The machine is equipped with 3 hard disks, disk1, disk2, and disk3. Use these three hard disks for RAID5 and install the operating system and related application software. Now it is necessary to port RAID5 to other machines to ensure that data files are available. Install the disk array to other machines. You can't see this array in my computer. Go to Disk Management. You can see that the system thinks this array is not stored outside. You can read the relevant data by specifying a new drive letter. However, it is necessary to look at the type and usage of the stored data file. If it is EXCHANGE DB, it cannot be used normally. If it is a doc file, it can be used normally. So the key to the problem is to look at the original machine installation mode and the working mode of the machine after switching, as well as the type and usage mode of the data. If it is an important server, you should still store the operating system, database, and log files on a physically separate hard disk. Of course, the cost will be high. Eggplant Hello, my machine is similar to the scene you designed. The operating system is not on the raid disk. If you directly move the raid disk (disk cabinet) to the new machine, you mean "the system thinks this array" It is not stored outside, then there is no fault tolerance function in this raid array. Can the system monitor the disk status of this array? ? Thank you. Because the amount of data is too large, I dare not rush to migrate, please elaborate on what I remember when Winnt, it seems that the raid information is stored in the registry, redo the system as long as the corresponding key value in the registry is imported, after win2000 It seems that there is no such key value success, thank you for your enthusiastic participation in this array disk directly connected to the new server, raid information and dynamic disk information are not lost, it seems that from win2k, soft raid information Write to the disk, and has nothing to do with the system, (as long as you do not switch to linux or other operating system (^_^)
