Create mirror windows 2000

Before you can start mirroring on the partners, you should create a current log backup on the original database and restore it to the future mirror database. For more information, see one of the following:. You can reconfigure the session to run in high-safety mode with automatic failover or in asynchronous, high-performance mode, as follows:.

If you want a high-safety mode session to support automatic failover, add a witness server instance. The database owner can turn off the witness for a database at any time. Turning off the witness is equivalent to having no witness, and automatic failover cannot occur. Alternatively, if you do not want automatic failover and you prefer to emphasize performance over availability, turn off transaction safety. Prepare a Mirror Database for Mirroring SQL Server Summarizes the steps for creating a mirror database or preparing a mirror database before resuming a suspended session.

Also provides links to how-to topics. Specify a Server Network Address Database Mirroring Describes the syntax of a server network address, how the address identifies the database mirroring endpoint of the server instance, and how to find the fully-qualified domain name of a system.

Example: Setting Up Database Mirroring Using Certificates Transact-SQL Contains an example of all the stages required to create a database mirroring session with a witness, using certificate-based authentication.

Upgrading Mirrored Instances. Skip to main content. This browser is no longer supported. Download Microsoft Edge More info. At that point the it only allows me to create a 7MB mirror volume. It's like it's looking at the C drive, seeing that it has a volume that already has a mirror associated with it the broken mirror from when the original drive failed and then it says "Well, you can't use that volume on C. I'll just give you an arbitrary 7MB that happens be left at the end of the C drive to mirror onto the D drive.

The C drive only had one volume on it that took up the whole disk. It was being mirrored onto the D drive. The C drive crashed and a Dell tech came out and moved the D drive into the primary master disk position C dirve and then intalled a new drive as the D drive. He then "broke the mirror" and packed up his gear and split.

Dell does not support software raid. So, that is what I'm left with. A C drive that was the old D drive, and a new D drive that won't allow me to create a mirror volume of more than 7MB. Does that make sense? Take the D: Drive back to an "unallocated space" state and use the following instructions to create the mirror I followed the instructions to the letter a few times.

One thing: I ran the diagnostic software that the hard drive manufacturer puts out and it said that Disk0 is failing. So, I got a brand new drive sent to me from Dell. That's my day, today I'm going to try and clone the C drive to the D drive, move the D drive into Disk0 position, hope that it boots correctly, install the brand new drive into D position, and see if I can mirror it then. Wish me luck!!!

Thanks for all you efforts to help me. Chaz Howell. Reply to author. Report message as abuse. Show original message.

We had two 80GB drives that were running as dynamic drives, software mirrored through the Microsoft Disk Manager, and were working just fine. Disk0 C: drive with MBR crashed. A dell service guy came out and moved Disk1 D: to become Disk0 C: and installed an identical hard drive to become Disk1 D:.

Here is a quote from one of our guys who dealt with this issue before I came onboard: As far I can understand the tech that Dell send was a little retarded the Disk 0 MBR failed and when he put in the new disk the system would not boot because it was looking to MBR on the new disk. Without any additional knowledge I did break the mirror and swapped the drives so the system could boot. Now, the system boots and runs just fine.

Both disks are recognized in the Disk Management tool. But, and here's the catch, no matter what I do, I cannot get a software mirror to run again. Specifically, when I create a new volume on Disk1 D: , the new drive, the "mirrored" option is grayed out. Basically, I'm stuck. I just cant' get the replacement drive to create a mirrored volume to get mirroring RAID1 running again. Once caveat: Althought the disks are identical DM reports them in their repsective properties windows as being Maxtor 6YM0 disks they don't seem to be the exact same size.

Disk0 C: says its capacity is Anything you could do to help, or anyone you know who you could forward this email to would be greatly appreciated. I came on as a tech guru to help this company out, and now I kind of look like a poser. Since, I can't fix this silly disk issue.

Help a brother save face and earn good karma! Disk1 must be at least as large as Disk0 if you have only one partition on Disk0. So you need to change the partition size on Disk0 to accomplish your goal. Jenny wu. Hi ChazHowell, Thanks for posting here. Dear D, Thanks for you reply. Yes, both disks have definitely been converted to Dynamic. This conversation is currently closed to new comments.

You should be able to. You can use any form of HDD does not matter. If you right click on "My computer" and go to "Manage". In there there is the Disk Manager. From Disk Manager you can setup those features. I haven't tried it yet with server but I've had mirrored duplexed drives with NT Server for a couple of years without any problems.

Should work with as well. You can mirror ANY kind of disk. Remember that disk should be both ide or both scsi, preferable the same or near the same size. Partitions sizes should be identical.
