MSA1000 & Windows 2003 Enterprise

I have two DL380G3 with HBA 2340(2214) and 2003 Enterprise. Any server can create/delete partition and format logical drives on MSA1000, but another server can`t see the work of it`s partner. As a result it sees logical disks partitioned, but not formated at all. attempt to format it return error "format unsuccessful". But I can delete partition and create and format it. So anothe server can`t see it. And so on.

Re: MSA1000 & Windows 2003 Enterprise

That is to be expected behaviour!!

A simple Windows system does not have the ability to concurrently share NTFS volumes with another one. You can consider yourself lucky that you have found it out early on.

You need to buy additional software like Polyserve or Veritas Cluster.

Alexander:

This result is normal, if you have Windows 2003 enterprise, you can try the Cluster services from Microsoft and use the wizard, declare the storage on the MSA100 like shared and only the storage declared like shared can be shared on both servers at the same time.

Re: MSA1000 & Windows 2003 Enterprise

Since when does Windows implement a shared file system?

Re: MSA1000 & Windows 2003 Enterprise

Thanks to all for the fast replay. But a try to describe slightly different situation. Step one: Connecting MSA1000 to DL380. Configure storage volumes and writing data to it. Disconnect server.
Step two: Connecting MSA1000 to another DL380. No data. All the volumes are not formated. Then recreate partitions format volumes write data. Disconnect server.
Step three: Connecting MSA100 to the first server. No data. All the volumes are not formated. Trouble?

Re: MSA1000 & Windows 2003 Enterprise

I'm not a Windows administrator, but I thought that Windows 2003 EE does not automatically mount 'new' volumes (it has never seem before). Enter:

> mountvol /E

and retry.

Re: MSA1000 & Windows 2003 Enterprise

Hi,

Can you post screenshots of what you see in Disk Management?
After step one, you just say "Disconnect server". Does that mean you shutdown the OS properly? And how are you connecting the servers to the MSA1000 - do you have a SAN Switch?

Regards,
Stephen

Re: MSA1000 & Windows 2003 Enterprise

Thanks for all. And special gratefulness to Uwe Zessin. Windows 2003 EE realy automatically mount 'new' volumes only on shared SCSI bus (MSA500), but not on fiber channel via HBA connection (MSA1000). Simply
assigned a letter to 'unformated' drive and all the data became visible. My apolgize for the greener question.

Re: MSA1000 & Windows 2003 Enterprise

hi, i am interested in your solution.
i have been doing the same sort of thing as your original post.
just received the msa1000 and have some vague idea of how it should work, in this fail over mode.
please could you explain your solution in more detail, i think it would help me a great deal.
regards
