osd_req_decode_sense_full - Decode sense information after execution.
: - osd_request to examine - Receives a more detailed error report information (optional). - Do not print to dmsg (Even if enabled) - Some commands act on multiple objects. Failed objects will be received here (optional) - Size of . - List of failing attributes (optional) - Size of .
After execution, osd_request results are analyzed using this function. The return code is the final disposition on the error. So it is possible that a CHECK_CONDITION was returned from target but this will return NO_ERROR, for example on recovered errors. All parameters are optional if caller does not need any returned information. Note: This function will also dump the error to dmsg according to settings of the SCSI_OSD_DPRINT_SENSE Kconfig value. Set if you know the command would routinely fail, to not spam the dmsg file. osd_err_priority - osd categorized return codes in ascending severity.
The categories are borrowed from the pnfs_osd_errno enum. See comments for translated Linux codes returned by osd_req_decode_sense.

osd_auto_detect_ver - Detect the OSD version, return Unique Identification
: OSD target lun handle : Capabilities authorizing OSD root read attributes access : Retrieved information uniquely identifying the osd target lun Note: odi->osdname must be kfreed by caller.
Auto detects the OSD version of the OSD target and sets the accordingly. Meanwhile also returns the "system id" and "osd name" root attributes which uniquely identify the OSD target. This member is usually called by the ULD. ULD users should call osduld_device_info(). This rutine allocates osd requests and memory at GFP_KERNEL level and might sleep.
