Ok, now the picture is more clear. It happened only with the virtual ports. With physical port and LUNs that defined with write cache enable rmmod succeeded, and on the messages file I see: [57972.480234] sd 40:0:0:1: [sdb] Synchronizing SCSI cache [57972.530263] sd 40:0:0:1: [sdb] Result: hostbyte=DID_NO_CONNECT driverbyte=DRIVER_OK,SUGGEST_OK While with virtual port I see only: [57972.480234] sd 40:0:0:1: [sdb] Synchronizing SCSI cache and never get the Result. Anyone has an idea? Thanks, Gal.
