Partition to Disk bridged device

[rnelson]

I created a Partition to Disk bridged device on Windows SBS 2008 using iStorage Server and it seemed to work fine when connected read-only. When I used CHAP authentication for full access I got a lot of disk errors logged on the Windows 7 client using the builtin initiator.

It seems that the initiator still haven't got the full access, you can view it at the Initiators view of iStorage Server Management Console, and see FAQs for help:

If you are using the version before 1.40, please upgrade it to the newest version.
If the problem can't be resolved, please tell me the following information:
Which version of iStorage Server? Version number and architecture (x32, x86 or Itanium).
Do you select any partition table construction or just leave RAW (Nothing selected) mapping?

[rnelson]

The initiator view does show full access. I've tried it with all combinations of "Hold and Update" and "Construct MBR" checked and unchecked.

This is with the latest version 1.60 (x64) on Windows SBS 2008 64 bit.

We found it, it heppens when client machine try to write Parition Table, but it is readonly and can't modified, the RAW (do not select Construct MBR and GPT) method is working without any problem.
We will improve the mechanism at the next version.
