11/12/2023 0 Comments Active boot disk serveraid driversThe choices that I can see would be:ġ: Manually re-create as performed previously on Server A.Ģ: Some other method of import or copy.īut I do not see how #2 can be achieved and I am also not sure whether #1 approach is possible. So I am wondering how I create the Logical Disks on Server B. The ServeRAID 6M does support IMPORT from Disk in Cluster MS Windows 200x mode. There is only ONE outstanding question that I have. RE: ServeRAID 6M - Windows 2003 - Disks re-synch ALWAYS on failover. (probably you have no problem, becouse if you have 5 disksĢ) You have to swap ServerA and B between servername and partnername. Warning: no disks can have scsi id 6 or 7: the corresponding locations on DS400 MUST be empty Step D: the previous op has copied all to card, but something is wrong and has to be changed:ġ) The card scsi ID is 7 while the scsi ID of 2nd card (this operation is used when your card fails, while the disks are good: in the disk there are the right array layout, while the new card, that come from Adapec, nothing knows about array layout) it is as you have migrated the storage from Srv1 to another but identical Srv2. Step C: boot Srv2 by CD, and import information from disk. Step B: leave disk to synchronize then shutdown Srv1. Step A: boot server1 by CD, cfg disk array (I think 1 RAID1 and 1 RAID5) check adapter SCSI-ID is 7 elect your 2 volumes in shared mode (cluster button), I don'remember if you can number volumes (however check if raid1 is vol1 and raid5 is vol2) write ServerA as servername and ServerB in partner name. The merge-group-number I believe is a sort of LUN. How you have noticed, the button Cluster in ServeRAID manager, is active only if you boot from ServeRAID CD. I read somewhere that Microsoft Clustering has difficulty with the second channel LUN identification. We are using Channel 2 on the 6M Controller. meaning that we should be able to do this. we are highly technical operating system level developers in satellite and cellular network software development. We flattened it and did a reinstall for technical reasons IBM did the initial installation in Japan. M Disk (Exchange) on Logical Disk 70 GB (RAID-1) Q Disk Quorum is on Logical Disk 18 GB (RAID-1) 2 ServeRAID 6M Controller 2 (2 channels) 2 LSI RAID integrated Controller 1 (2 channels) it is to be a test environment for MS Exchange stuff.

Some years ago, I wrote something about this FAQ491-3942: How to correctly setup MSCS (windows cluster) in ServeRAID environment. Tell us also the BIOS level of the card,Īnd level of Windows device driver, and the type-model of the servers. I don'know what is your situation, you are in production, When OS comes on and the part of Cluster IBM solutions starts, all return ok. See lost the disks, at bios level, when you have not yet loaded OS and then IBM-Windows-ServeRAID-DeviceDriver is not started. Well, when happens a failover (suppose you reboot host2),Ī scsi bus reset is sent, and host1 take control of virtual disks. Using ServeRAID Cards (they are not simple scsi but have also RAID capability), BOTH cards MUST know the same ARRAY LAYOUT. (ie: disk0 and 1 are in RAID1, disk 2,3,4 in RAID5). Is the storage that knows the ARRAY layout and does RAID policy Typically on host there is just a scsi card, not a RAID one: the RAID controller is on the storage. However, the way to obtain Cluster by IBM ServeRAID, is almost different from the others. Which type of storage have you linked to hosts ?
