As others pointed out there is a module param for the max lun for iscsi_tcp, but that should actually be limited by a libiscsi/scsi-ml limit. libiscsi uses a function named int_to_scsilun in drivers/scsi/scsi_scan.c and as you can see that only implments 2 levels. libiscsi/iscsi_tcp also does not do the device scanning (the iscsi layer only finds the targets) so we are limited by scsi_scan.c. To get the limits for that do "modinfo scsi_mod". There is also a limit on the number of targets. Because we allocate a scsi_host per session, and the scsi layer uses a unsigned short for the host number the number of targets is 2^16. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "open-iscsi" group.
