We have 2 servers - ServerA and ServerB. These are connected to an external storage. We are using IBM and its associated software IBM ServeRAID. Both servers have been connected to the external storgae succesfully. When Serbe B was booted up, we could see the physical dirves in the ServeRAID but not within NT2000 computer management. Running ipshahto.exe brought up the devices on the ServerB but then made the devices on Server A DDD (Defunct Disk Drive). Running ipshahto.exe on Server A then brought the drives back on Server A but made Server B - DDD (Defunct Disk Drive).

Has anyone come across this. Please help.

Hi,
not sure if I'm following you here - are you aware that only one server can control the disks at one time? This means that the server that doesn't control the disks at that point will show them as defunct. The hto in the name of the ipshahtoutility actually stands for 'hostile take over'. This means that it siezes control of the disks from whichever machine currently 'owns' them and passes control to whichever machine the util was run on. The cluster documentation on the serveraid CD gives comprehensive instructions for installing the cluster service on IBM kit, including tests you can run to ensure that the installation has been succssful. Hope this helps...

Does that mean, we will not be able to assign any drive letters to Server B shared disk (DDD) whilst Server A is online. Also on Server A we were not able to save a file. Does it also mean it will show up with red exclamation marks.

On booting up Server B, it came up with 2 Logical drives offline and 4 drives DDD. Is this ok?

We are using the instructions that comes on the ServeRAID CD.

Thank you very much
