dude2cool,
Thanks for the reply

"comma" is already there in the variable $mj. Below is the debug output. Problem is grepping the major & minor number from the hdiskpower lists


HTML Code:
+ ls -l /dev/asm_disk1 /dev/asm_disk2 /dev/asm_disk3 /dev/asm_spfile
+ 1> /tmp/input10158174
+ cat /tmp/input10158174
+ read line
+ + echo crw-r--r-- 1 oracle dba 34, 3 Jun 21 20:06 /dev/asm_disk1
+ awk {print $5}
mj=34,
+ + awk {print $6}
+ echo crw-r--r-- 1 oracle dba 34, 3 Jun 21 20:06 /dev/asm_disk1
mi=3
+ + awk {print $10}
+ echo crw-r--r-- 1 oracle dba 34, 3 Jun 21 20:06 /dev/asm_disk1
asm_disk=/dev/asm_disk1
+ ls -l /dev/hdiskpower0 /dev/hdiskpower1 /dev/hdiskpower10 /dev/hdiskpower11 /dev/hdiskpower2 /dev/hdiskpower3 /dev/hdiskpower4 /dev/hdiskpower5 /dev/hdiskpower6 /dev/hdiskpower7 /dev/hdiskpower8 /dev/hdiskpower9
+ grep 34, 3
+ awk {print $10}
+ 1> /tmp/powerdiskinfo.rpt
Below is the error i am getting while grepping the major & minor number

HTML Code:
 
$ ls -l /dev/hdiskpower* |  grep 34, 11
grep: can't open 11
need to grep like below.

HTML Code:
ls -l /dev/hdiskpower* |  grep '34, 11'
 
brw-rw----    1 root     system       34, 11 May 16 2011  /dev/hdiskpower11

fdformat

FDFORMAT(8)						     Linux Programmer's Manual						       FDFORMAT(8)

NAME

       fdformat - Low-level formats a floppy disk

SYNOPSIS

       fdformat [ -n ] device

DESCRIPTION

       fdformat  does  a  low  level  format on a floppy disk.	device is usually one of the following (for floppy devices, the major = 2, and the
       minor is shown for informational purposes only):

	      /dev/fd0d360  (minor = 4)
	      /dev/fd0h1200 (minor = 8)
	      /dev/fd0D360  (minor = 12)
	      /dev/fd0H360  (minor = 12)
	      /dev/fd0D720  (minor = 16)
	      /dev/fd0H720  (minor = 16)
	      /dev/fd0h360  (minor = 20)
	      /dev/fd0h720  (minor = 24)
	      /dev/fd0H1440 (minor = 28)

	      /dev/fd1d360  (minor = 5)
	      /dev/fd1h1200 (minor = 9)
	      /dev/fd1D360  (minor = 13)
	      /dev/fd1H360  (minor = 13)
	      /dev/fd1D720  (minor = 17)
	      /dev/fd1H720  (minor = 17)
	      /dev/fd1h360  (minor = 21)
	      /dev/fd1h720  (minor = 25)
	      /dev/fd1H1440 (minor = 29)

       The generic floppy devices, /dev/fd0 and /dev/fd1, will fail to work with fdformat when a non-standard format is being used, or if the for-
       mat has not been autodetected earlier.  In this case, use setfdprm(8) to load the disk parameters.

OPTIONS

       -n     No verify.  This option will disable the verification that is performed after the format.

SEE ALSO

       fd(4), setfdprm(8), mkfs(8), emkfs(8)
