Microsoft ISCI initiator / Drive not accessible, the device is not ready

Last Modified: 2008-01-09
I am having a problem with the microsoft isci initiator on windows 2003 server. I had a vitual storage switch lose a backend scsi controller connnection to a scsi sata array. The result was that I lost all targets that were attached to the the defined LUN/controller port on the array.

I have managed to find a work around in order to be able to once again expose all luns and associated targets, and hence have all iscsi targets available. However, what I am finding, is that the server that was previoulsy attached to the lost targets, is unable to read the boot record, and ascertain the drive details. As far as it is concerned, it is a completely new volume ready to be formated (RAW). Whowever this is noty the case. I am able to attach to all drives that are behaving in this manner on a completely different server, and browse the volumes normally.

I have gone as far as unexposing the targets on the iscsi switch, and renaming the targets, attaching them to the server....but the same issue results. These new target are still unreadable.

I have re-installed the iscsi initiator... but the same results
So, if anyone can provide some words of wisdom, I would appreciate it.

I have had similar problems and had to use a partition recovery application to recover the partition.  One that I've used is Active Partition Recovery which can be found at http://www.partition-recovery.com.


Appreciate the response...

I did find this answer, but have yet to inact upon it... the bigger issue is why did the hardware fail? we are taking this up with the vendor(s).
For Windows 2000 Server and Windows Server 2003: a. Right-click My
Computer, and then click Manage.
b. In the left pane, click Device Manager.
c. On the View menu, click Show hidden devices.
d. In the right pane, expand Non-Plug and Play Drivers, and then
double-click Clusdisk.
e. On the Driver tab, in the Type box, click Disabled, and then click

Reboot and you should then see your drives.


The above mentioned solution did not work for me, hence I have an option to either involve microsoft, or just blow the box away. In any case this project is currently been placed on the shelf.
If you check out Active Partition Recovery, you can DL a trial version which will show you the partition...you just have to purchase it to recover it.  This would, at least help you towards resolving the issue w/out any additional cost.  It might even be able to fix your problem at a minimal cost.  (I think the software is something like $30 or $40.)


Thanks for additional info... I'll definately try that.

It is just strange that no matter what I do to these partitions, re-target... nothing changes from the hosts perspective.... I can't even re-format the partition.

Any other box that I attach these drives to, has complete access to the partitions.
