Unable to connect to target.

Han · Tue May 29, 2007 2:20 pm

2 VM's running on VMware Workstation 6
1 VM Windows XP SP2 MS iSCSI initiator 2.04
1 VM Longhorn beta 3 StarWind 3.2.3.20070524 with one 16 GB DiskBridge target.
Both VM's firewall switched of. XP client is able to see the target but when I want to initialize the disk this error appears in the System Log: Unspecified error (80004005).

Hello Han,

would you please send us StarWind logs from C:\Program Files\Rocket Division Software\StarWind\logs\ directory? We'll try to understand what's wrong.

Please, send logs at bohdan@rocketdivision.com

Hello Han,

There are such errors in your log files:
IMAGE: *** ImageFile_ReadWriteSectors: WriteFileEx(0x00ED0000, 512, 0x0) failed (19).
Error code 19 means "The media is write protected".
Please, check if your vmware virtual disk is write protected. Also you can use ImageFile instead of DiskBridge to check if same error occurs.

If it's Windows 2008 Server blocking access to the raw disk we'll have to use back door to obain write-valid device handle. Some feedback from the OP is required

Ok I had the time to try Windows Server 2003 (plain SP1) instead of 2008 beta 3. Configured StarWind the same way and it works perfect. So it looks like a 2008 issue.
Who or what is the OP?

There's really something with 2008 Server firewall... Our QA guys are having hard times to make it work (other things, non-iSCSI) as well.

Ok so what can I do to help. I was able to connect so one would think the firewall wasn't the issue... just wasn't able to partition the exported disk.
I know port 3260 is the iSCSI port. But when I issue a netstat -an when the StarWind service runs it seems to listen on 3261 too. What's the purpose of this port?
Also I'm a bit confused about security. Authentication can be required twice: once for the connection between management console and the service and the other for the connection between iSCSI initiator and StarWind (target). Correct?
The console connects to the service through port 3260. Correct?
So does the console configures the service through SCSI commands or is there an other protocol used through port 3260 for communication between console and service?

Unable to partition is Windows 2008 server disk access write issue, firewall is another thing. Not iSCSI ralated

Ok so the issue I've seen is a disk access issue.
How about the other questions. I've read the help and did some experiments but I still do not completely understand. Or should I start a new thread?

Yes. We already have dedicated component for obtaining write-enabled disk device handle. We hoped we'll not have to use it but looks like we should

Yes. Security is applied twice. And yes, it's better to start new thread

Sorry, I've just missed second part of the posting
