Fornow, let me call these 'fast' and 'slow' languages, on the groundsthat it is a slightly less loaded set of terms than other possibleones.

It's recently struck me that one of the effects of this language gapon the 'slow' languages is that it basically cuts off your ability

Here's something important to know about Solaris's MPxIO multipathing : MPxIO identifies disks only by theirserial numbers and identifiers . So if two Solaris devices have thesame serial number, MPxIO concludes that they are two paths to the samephysical disk; it has no actual knowledge of underlying path issues,such as iSCSI target identifiers.

This matters a great deal on iSCSI, because at least some iSCSIinitiators have serial numbers that are set in software. If youaccidentally duplicate some serial numbers between different disks,Solaris
