MPATH_PERSISTENT_RESERVE_OUT(3) 			     Library Functions Manual				   MPATH_PERSISTENT_RESERVE_OUT(3)

NAME

       mpath_persistent_reserve_out

SYNOPSIS

       #include <mpath_persist.h>

       int mpath_persistent_reserve_out (int fd, int rq_servact, struct prin_resp *resp, int noisy, int verbose)

DESCRIPTION

       The function in the mpath_persistent_reserve_out() sends PR OUT command to the DM device and gets the response.
       Parameters:
       fd The file descriptor of a multipath device. Input argument.
       rq_servact PROUT command service action. Input argument
       rq_scope Persistent reservation scope. The value should be always LU_SCOPE (0h).
       rq_type Persistent reservation type. The valid values of persistent reservation types are
	     5h (Write exclusive - registrants only)
	     6h (Exclusive access - registrants only)
	     7h (Write exclusive - All registrants)
	     8h (Exclusive access - All registrants).
       paramp  PROUT  command parameter data. The paramp is a struct which describes PROUT parameter list. Caller should manage the memory alloca-
       tion of this structure.
       noisy Turn on debugging trace: Input argument. 0->Disable, 1->Enable.
       verbose Set verbosity level. Input argument. value: 0 to 3. 0->Crits and Errors, 1->Warnings, 2->Info, 3->Debug

RETURNS

       MPATH_PR_SUCCESS if PR command successful else returns any one of the status mentioned below
       MPATH_PR_SYNTAX_ERROR if syntax error or invalid parameter
       MPATH_PR_SENSE_NOT_READY if command fails with [sk,asc,ascq: 0x2,*,*]
       MPATH_PR_SENSE_MEDIUM_ERROR if command fails with [sk,asc,ascq: 0x3,*,*]
       MPATH_PR_SENSE_HARDWARE_ERROR if command fails with [sk,asc,ascq: 0x4,*,*]
       MPATH_PR_SENSE_INVALID_OP if command fails with [sk,asc,ascq: 0x5,0x20,0x0]
       MPATH_PR_ILLEGAL_REQ if command fails with [sk,asc,ascq: 0x5,*,*]
       MPATH_PR_SENSE_UNIT_ATTENTION if command fails with [sk,asc,ascq: 0x6,*,*]
       MPATH_PR_SENSE_ABORTED_COMMAND if command fails with [sk,asc,ascq: 0xb,*,*]
       MPATH_PR_NO_SENSE if command fails with [sk,asc,ascq: 0x0,*,*]
       MPATH_PR_SENSE_MALFORMED if command fails with SCSI command malformed
       MPATH_PR_RESERV_CONFLICT if command fails with reservation conflict
       MPATH_PR_FILE_ERROR if command fails while accessing file (device node) problems(e.g. not found)
       MPATH_PR_DMMP_ERROR if Device Mapper related error.(e.g Error in getting dm info)
       MPATH_PR_OTHER if other error/warning has occurred(e.g transport or driver error)

NAME

       scsi_validate_sense - find descriptor in SCSI sense data

SYNOPSIS

       #include <sys/scsi/scsi.h>

       int scsi_validate_sense(uint8_t *sense_buffer, int sense_buf_len,
	    int *flags);

INTERFACE LEVEL

       Solaris DDI specific (Solaris DDI).

PARAMETERS

       sense_buffer	Pointer to a buffer containing SCSI sense data. The sense data is expected in wire format starting at the response code.

       sense_buf_len	Length of sense buffer in bytes.

       flags		Returns additional properties of the sense data.

DESCRIPTION

       The  scsi_validate_sense() function returns the format of the sense data contained in the provided sense buffer. If the response code field
       in the sense data is not recognized or if there is not enough sense data to include sense key, asc,  and  ascq  then  scsi_validate_sense()
       returns	SENSE_UNUSABLE.  If  the buffer contains usable sense data in fixed format, the function returns SENSE_FIXED_FORMAT. If the buffer
       contains usable sense data in descriptor format, the function returns SENSE_DESCR_FORMAT.

       The following flags may be set as appropriate depending on the sense data:

       SNS_BUF_OVERFLOW    The sense data buffer provided for the request is too small to hold all the sense data.

       SNS_BUF_DEFERRED    The sense data contained in the buffer relates to an error that has occurred during the processing  of  a  successfully
			   completed command, such as a cached write that could not be commited to the media.

RETURN VALUES

       SENSE_UNUSABLE	     The response code from the sense data is unrecognized or not enough sense data present to provide the sense key, asc,
			     and ascq.

       SENSE_FIXED_FORMAT    The sense data in the buffer is in "fixed format".

       SENSE_DESCR_FORMAT    The sense data in the buffer is in "descriptor format".

CONTEXT

       The scsi_validate_sense() function can be called from user or interrupt context.
