So the block disks show up fine.

Is it a legit SCSI behaviour? The kernel intoragates the disks and that is what it gets. It reports to you these errors. There is no need to send a Request Sense command as the Test Unit Ready has already provided you the SCSI error, along with the ASC/ASCQ values, as you can see: > sd 6:0:0:1: Device not ready: <6>: Current: sense key: Not Ready > Additional sense: Logical unit not ready, cause not reportable The next step for enterprise storages, such as the HP StorageWorks is to issue a START SCSI command - which is what you should see if you are using multipath. The path checker would start the LUN. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "open-iscsi" group.
