I imagine any two OS instances each issuing SCSI commands separately to the same target device could lead to unexpected states on the target device. I can't see how the target being part of an SVM metaset would make a difference in one OS instance not knowing that the device had been 'changed' by another OS instance. Steffen > > TIA, > Rushi
