Absolutely. Are you looking for exactly one line, or more? Are the columns separated by whitespace? Assuming yes to all the answers above:
Code:
my $target;
if (open(FOO,$_)) { 
 while ($_=<FOO>) { 
   next unless /OXT/;  # find OXT anywhere in line.
   $target=(split)[4];
   last;
 }
 close(FOO); # forgot this last time, though not really necessary.
}
# 4th field in $target

scsi_address

scsi_address(9S)					    Data Structures for Drivers 					  scsi_address(9S)

NAME

       scsi_address - SCSI address structure

SYNOPSIS

       #include <sys/scsi/scsi.h>

INTERFACE LEVEL

       Solaris architecture specific (Solaris DDI)

DESCRIPTION

       A scsi_address structure defines the addressing components for a SCSI target device. The address of the target device is separated into two
       components: target number and logical unit number. The two addressing components are used to uniquely identify any  type  of  SCSI  device;
       however, most devices can be addressed with the target component of the address.

       In  the case where only the target component is used to address the device, the logical unit should be set to  0. If the SCSI target device
       supports logical units, then the HBA must interpret the logical units field of the data structure.

       The pkt_address member of a scsi_pkt(9S) is initialized by scsi_init_pkt(9F).

STRUCTURE MEMBERS

       scsi_hba_tran_t	 *a_hba_tran;  /* Transport vectors for the SCSI bus */
       ushort_t 	 a_target;     /* SCSI target id */
       uchar_t		 a_lun;        /* SCSI logical unit */

       a_hba_tran is a pointer to the controlling HBA's transport vector structure. The SCSA interface uses  this  field  to  pass  any  transport
       requests from the SCSI target device drivers to the HBA driver.

       a_target is the target component of the SCSI address.

       a_lun is the logical unit component of the SCSI address. The logical unit is used to further distinguish a SCSI target device that supports
       multiple logical units from one that does not. The makecom(9F) family of functions use the a_lun field to set the logical unit field in the
       SCSI CDB, for compatibility with SCSI-1.
