iSCSI: Notifications on error

["Lakshmi Ramasubramanian" <nramas@windows.microsoft.com>]

Title: Message

If a command fails at the SCSI layer (on the target side), the driver

can freeze the queue, and fail all requests till the queue is unfreezed.

The target needs to tell the initiator about the queue freeze condition

so that an initiator can issue an unfreeze request.

 

Currently there is no way (as much as I could understand) in the spec

to do such a thing. We can use vendor specific Async messages, but that

will cause interop problems.

 

Is it reasonable to request for a mechanism to do the above in the iSCSI

spec?

 

thanks!
