If your file structure is always as displayed above, i.e. the serial in in the next line after device name, try
Code:
awk 'BEGIN{print "DEVICE NAME\tSERIAL"} /DEVICE NAME/ {printf "%s\t", $5; getline; print substr($2, length($2)-3)}' file
DEVICE NAME    SERIAL
hdisk9    1021
hdisk10    1022
hdisk11    1025
hdisk12    1026
hdisk13    1027

scsi_ready

SCSI_READY(8)							     SG3_UTILS							     SCSI_READY(8)

NAME

       scsi_ready - do SCSI TEST UNIT READY on devices

SYNOPSIS

       scsi_ready [--brief] [--help] [--verbose] DEVICE [DEVICE]*

DESCRIPTION

       This bash shell script calls the sg_turs utility on each given DEVICE. This will send a SCSI TEST UNIT READY command to each DEVICE. Disks,
       tape drives and DVD/BD players amongst others may respond to this SCSI command.

OPTIONS

       Arguments to long options are mandatory for short options as well.

       -b, --brief
	      for each DEVICE given output a line containing either '	 ready' or '	device not ready'. If DEVICE is  not  found  or  there	is
	      another serious error then an error message will appear instead.

       -h, --help
	      print out the usage message then exit.

       -v, --verbose
	      increase level or verbosity.

EXIT STATUS

       The  exit  status  of this script is 0 when it is successful. Otherwise the exit status is that of the last sg_turs utility called. See the
       sg3_utils(8) man page.
