is that possible to keep statements in any loop??
Hi,

Actually i stored all validdisks in one array and corresponding partitions required for all individual disks in other array..

Example:
Validdisks[$diskcnt]=dsk2 dsk3 dsk5
 ValidPartition[$Partitioncnt]=4 4 3

Now i have to create domain..

Domain creation can be done by below commands:
fs_setup -d /dev/disk/${Validdisks[0]}a -n ${cfsfailover_dmn} -m ${cfsfailover_mnt}"
addvol /dev/disk/${Validdisks[$diskcnt]}h ${cfsfailover_dmn}
addvol /dev/disk/${Validdisks[$diskcnt]}g ${cfsfailover_dmn}
addvol /dev/disk/${Validdisks[$diskcnt]}b ${cfsfailover_dmn}
addvol /dev/disk/${Validdisks[$diskcnt]}a ${cfsfailover_dmn}

But tricky is there in creating domain...
Lets go first with Validdisk[0] element:
============================
By checking the elements in ValidPartition[$Partitioncnt] array,i need to create.. Since first element of ValidPartition[0]=4 means (we have to use a,b,g,h)

Domain creation for one disk wil be as below:
fs_setup -d /dev/disk/${Validdisks[0]}a -n ${cfsfailover_dmn} -m ${cfsfailover_mnt}"
addvol /dev/disk/${Validdisks[$diskcnt]}b ${cfsfailover_dmn}
addvol /dev/disk/${Validdisks[$diskcnt]}g ${cfsfailover_dmn}
addvol /dev/disk/${Validdisks[$diskcnt]}h ${cfsfailover_dmn}
And lets go with second element of validdisk[1]
Now here By checking the elements in ValidPartition[1] here it has 4 so again domain creation for second disk must be as below:

addvol /dev/disk/${Validdisks[$diskcnt]}a ${cfsfailover_dmn}
addvol /dev/disk/${Validdisks[$diskcnt]}b ${cfsfailover_dmn}
addvol /dev/disk/${Validdisks[$diskcnt]}g ${cfsfailover_dmn}
addvol /dev/disk/${Validdisks[$diskcnt]}h ${cfsfailover_dmn}

And lets go with third element of Validdisk[2]
Now here By checking the elements in ValidPartition[2] here it has 3 so use a,b,g only

addvol /dev/disk/${Validdisks[$diskcnt]}a ${cfsfailover_dmn}
addvol /dev/disk/${Validdisks[$diskcnt]}b ${cfsfailover_dmn}
addvol /dev/disk/${Validdisks[$diskcnt]}g ${cfsfailover_dmn}

And note that, "
fs_setup -d /dev/disk/${Validdisks[0]}a -n ${cfsfailover_dmn} -m ${cfsfailover_mnt}"
that should be written only once for first disk.. Later on we have to use addvol statements...Could you please help me by doing this in KSH scripting..Is that possible to keep in for loop?? Please provide your inputs..Thanks,Mansa

partx

PARTX(8)						       System Administration							  PARTX(8)

NAME

       partx - tell the kernel about the presence and numbering of on-disk partitions

SYNOPSIS

       partx [-a|-d|-P|-r|-s|-u] [-t type] [-n M:N] [-] disk
       partx [-a|-d|-P|-r|-s|-u] [-t type] partition [disk]

DESCRIPTION

       Given a device or disk-image, partx tries to parse the partition table and list its contents.  It can also tell the kernel to add or remove
       partitions from its bookkeeping.

       The disk argument is optional when a partition argument is provided.  To force scanning a partition as if it were a whole disk (for example
       to list nested subpartitions), use the argument "-" (hyphen-minus).  For example:

	      partx --show - /dev/sda3

       This will see sda3 as a whole-disk rather than as a partition.

       partx  is  not  an fdisk program - adding and removing partitions does not change the disk, it just tells the kernel about the presence and
       numbering of on-disk partitions.

OPTIONS

       -a, --add
	      Add the specified partitions, or read the disk and add all partitions.

       -b, --bytes
	      Print the SIZE column in bytes rather than in human-readable format.

       -d, --delete
	      Delete the specified partitions or all partitions.

       -g, --noheadings
	      Do not print a header line with --show or --raw.

       -l, --list
	      List the partitions.  Note that all numbers are in 512-byte sectors.  This output format is DEPRECATED in favour of --show.  Do  not
	      use it in newly written scripts.

       -n, --nr M:N
	      Specify  the range of partitions.  For backward compatibility also the format M-N is supported.  The range may contain negative num-
	      bers, for example --nr -1:-1 means the last partition, and --nr -2:-1 means the last two partitions.  Supported range specifications
	      are:

		     M	    Specifies just one partition (e.g. --nr 3).

		     M:     Specifies the lower limit only (e.g. --nr 2:).

		     :N     Specifies the upper limit only (e.g. --nr :4).

		     M:N    Specifies the lower and upper limits (e.g. --nr 2:4).

       -o, --output list
	      Define the output columns to use for --show, --pairs and --raw output.  If no output arrangement is specified, then a default set is
	      used.  Use --help to get list of all supported columns.  This option cannot be combined with the --add, --delete, --update or --list
	      options.

       -P, --pairs
	      List the partitions using the KEY="value" format.

       -r, --raw
	      List the partitions using the raw output format.

       -s, --show
	      List  the partitions.  The output columns can be selected and rearranged with the --output option.  All numbers (except SIZE) are in
	      512-byte sectors.

       -t, --type type
	      Specify the partition table type.

       --list-types
	      List supported partition types and exit.

       -u, --update
	      Update the specified partitions.

       -S, --sector-size size
	      Overwrite default sector size.

       -v, --verbose
	      Verbose mode.

       -V, --version
	      Display version information and exit.

       -h, --help
	      Display help text and exit.

EXAMPLES

       partx --show /dev/sdb3
       partx --show --nr 3 /dev/sdb
       partx --show /dev/sdb3 /dev/sdb
	      All three commands list partition 3 of /dev/sdb.

       partx --show - /dev/sdb3
	      Lists all subpartitions on /dev/sdb3 (the device is used as whole-disk).

       partx -o START -g --nr 5 /dev/sdb
	      Prints the start sector of partition 5 on /dev/sdb without header.

       partx -o SECTORS,SIZE /dev/sda5 /dev/sda
	      Lists the length in sectors and human-readable size of partition 5 on /dev/sda.

       partx --add --nr 3:5 /dev/sdd
	      Adds all available partitions from 3 to 5 (inclusive) on /dev/sdd.

       partx -d --nr :-1 /dev/sdd
	      Removes the last partition on /dev/sdd.
