[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] iSCSI - Recovery LevelsThere seems to be consensus around the fact the recovery leves are good and no clear consensus about hpow many should there be (2 or 3). As there is no chance to settle this until 08 gets out I suggest intrdocucing a generic key=value pair (RecoveryLevel) and remove the existing keys (CommmandFailoverSupport and CommandReplaySupport). RecoveryLevel will be defined as follows: 01 RecoveryLevel Use: LO Who can send: Initiator and Target RecoveryLevel=<0 to x> Default is 0. Initiator and target negotiate the recovery level supported. The minimum of the two values is selected. Recovery levels represent a combination of recovery capabilities. Each recovery level includes all the capabilities of the lower recovery levels and adds to them some new ones. In the recovery mechanisms descriptions some specific recovery capabilities are used. Those are mapped to levels as follows: 0 - SessionRecovery 1 - CommandFailoverSupport and CommandReplaySupport [TBD] Comments? Julo
