Operating Systems SCO Tape Drive (/dev/rct0) donot work sometimes Post 302603455 by hicksd8 on Thursday 1st of March 2012 04:33:21 AM

Yes, I agree but, adding to my previous post, the reboot gets the SCSI adapter to issue a SCSI reset to the tape drive and it appears that this is enough to make it work. Therefore, SCSI communication is most likely the issue hence my comment about re-seating the cables, etc.

NAME
i2o_scsi - an I2O OS specific module that supports SCSA interface. DESCRIPTION
The i2o_scsi OSM module is a SCSI HBA driver that supports the SCSA interface. It supports both SCSI Adapter Class and SCSI Peripheral Class functions. It translates the SCSI packet coming down from the SCSA into an I2O SCSI Peripheral Class message, passes it along to the IOP which in turn passes it to the HDM (hardware specific module). It also uses SCSI Adapter Class functions to manage the SCSI adapter and SCSI bus. For each SCSI Adapter Class I2O device (a SCSI con- troller), it claims the SCSI Peripheral class devices which are attached to that port. The existing SCSI target drivers which use the SCSA interface should only work with i2o_scsi. This includes target drivers like sd, st and so on. FILES
