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

foreach
foreach(n) Tcl Built-In Commands foreach(n)
__________________________________________________________________________________________________________________________________________________
NAME
foreach - Iterate over all elements in one or more lists
SYNOPSIS
foreach varname list body
foreach varlist1 list1 ?varlist2 list2 ...? body
_________________________________________________________________
DESCRIPTION
The foreach command implements a loop where the loop variable(s) take on values from one or more lists. In the simplest case there is one
loop variable, varname, and one list, list, that is a list of values to assign to varname. The body argument is a Tcl script. For each
element of list (in order from first to last), foreach assigns the contents of the element to varname as if the lindex command had been
used to extract the element, then calls the Tcl interpreter to execute body.
In the general case there can be more than one value list (e.g., list1 and list2), and each value list can be associated with a list of
loop variables (e.g., varlist1 and varlist2). During each iteration of the loop the variables of each varlist are assigned consecutive
values from the corresponding list. Values in each list are used in order from first to last, and each value is used exactly once. The
total number of loop iterations is large enough to use up all the values from all the value lists. If a value list does not contain enough
elements for each of its loop variables in each iteration, empty values are used for the missing elements.
The break and continue statements may be invoked inside body, with the same effect as in the for command. Foreach returns an empty string.
EXAMPLES
This loop prints every value in a list together with the square and cube of the value:
set values {1 3 5 7 2 4 6 8} ;# Odd numbers first, for fun!
puts "Value Square Cube" ;# Neat-looking header
foreach x $values { ;# Now loop and print...
puts " $x [expr {$x**2}] [expr {$x**3}]"
}
The following loop uses i and j as loop variables to iterate over pairs of elements of a single list.
set x {}
foreach {i j} {a b c d e f} {
lappend x $j $i
}
# The value of x is "b a d c f e"
# There are 3 iterations of the loop.
The next loop uses i and j to iterate over two lists in parallel.
set x {}
foreach i {a b c} j {d e f g} {
lappend x $i $j
}
# The value of x is "a d b e c f {} g"
# There are 4 iterations of the loop.
The two forms are combined in the following example.
set x {}
foreach i {a b c} {j k} {d e f g} {
lappend x $i $j $k
}
# The value of x is "a d e b f g c {} {}"
# There are 3 iterations of the loop.
