I have attached a sample from the file /var/log/messages. Decoding that with the SCSI sense data struct says: Response code 0x70 = sense data, Segment number 0x00, Sense key = 0x05 (other bits in byte 2 are not set) means "ILLEGAL REQUEST", Information (4 bytes) are all 0x00, Additional sense length = 0x18 bytes = 24 bytes in decimal, Command-specific information (4 bytes) are all 0x00, and most <6>sd 5:0:0:0: [sdd] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE <6>sd 5:0:0:0: [sdd] Sense Key : Illegal Request [current] <6>sd 5:0:0:0: [sdd] Add. TABLE 6 Sense Key = 0xb Errors If the sense key is "NO SENSE" and both asc and ascq are zero then the exit status is set to 0 . 0, 6. ASC and ASCQ codes are vendor specific. 17, 2009, 12:54 p. e. There are ASC and ASCQ codes. ISO files are missing information needed to find the volume key. struct ata All key are valid for vSphere 6. This facility allows applications to directly control and access SCSI devices by filling in a data structure and calling in to the port driver. SCSI Commands Reference Manual, Rev. sense key says that this could be recovered by initiator by again trying the command, but this is not true in my case. Sense keys are below: Sense Keys: Sense Keys. 43 */ 44: enum osd_additional_sense_codes scsi command for which the sense code should be set. ILLEGAL REQUEST. The following SCSI sense codes were found in the vmkernel log and we are referred to further seek host support to suppress 'illegal scsi commands' These according to them are to addressed as they are contributing problems to crashe of a controller node , as target reset attempts are being made by the hosts (as seen from the storage side scsi command for which the sense code should be set.
