![]() When Remote Copy, Peer Persistence or Peer Motion is configured and one storage controller is configured as Active/Optimized (AO) and the other as Standby (in these configurations 3PAR secondary paths don’t support Active/Non-Optimized (ANO) state ), the standby paths will not be read-write and the SCSI PR registration cannot be done on those paths and so the above error message will be generated.ĭue to these limitations with the standby paths not accepting i/o and impacting SCSI PR registrations, this configuration is unsupported. If the array is configured as part of a Remote Copy, Peer Persistence or Peer Motion setup, it will act in ALUA mode. However the array might be only A/A in particular configurations- for example as a single controller or two controller configuration where both storage controllers are configured as A/A. ![]() SCSI error occurred on Path c9t21420002AC0203A5d214s2(243/650): opcode=0x5f reported illegal request (status=0x2, key=0x5, asc=0x26, ascq=0x0) invalid field in parameter list CauseģPar arrays are A/A by default and will be claimed by our asl as A/A. SCSI PR register cmd failed with “ opcode=0x5f reported illegal request (status=0x2, key=0x5, asc=0x26, ascq=0x0) invalid field in parameter list ” reported on InfoScale systems with 3PAR storage.
