[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] RE: IPS-All: WG Last Call on "iSCSI Naming and Discovery"Hello, One aspect of the Naming and Discovery draft that I find misleading lies in the sentence in Section B.3 "The gateway may manufacture its own iSCSI Names, or use those provided by the real devices." Now B.3 deals with non-iSCSI devices, so does the phrase "those provided by the real devices" refer to non-iSCSI devices providing an iSCSI Name? I read "those provided by the real devices" as the native identifiers (i.e. FC WWN). This may lead to the conclusion that a Gateway can use the "eui." form of the iSCSI name in a fairly straight-forward manner. Unfortunately, we know is not true (at least for the case where multiple gateways can see the same device on a SAN). So - I suggest a caveat is warranted, like "It is the responsibility of the gateway to ensure the uniqueness of any iSCSI name it manufactures. The gateway may need to account for multiple gateways having access to a single real device". Now - of course I would REALLY like to see something done at the naming level that would allow gateway vendors to preserve some part of the identity of the real device in a non-proprietary fashion. But at least alerting readers to the problem would be a good step. Regards, Rob.
