Hello,

I'm trying to setup oracle on linux red hat enterprise server 5 (running in vmware)

I have 4 10GB hard drives setup for this,

this is the script required to setup linux for asm that I'm having the error with

the error I get is bash: losetup: command not found

the only section of the script that generates an error is the "losetup" part

I'm executing as the root user
Run the following script as the root user. 
This sets up the loop devices to provide the multiple hard drives for ASM.
This is the script:
-------------------------------------------------------------------------------------------------
 
[ -d /u01/asmdisks ] || {
mkdir /u01/asmdisks
chown oracle:oinstall /u01/asmdisks
chmod 777  /u01/asmdisks
}
 
if [ ! -f /u01/asmdisks/data1.dsk ]
    then
        dd if=/dev/zero of=/u01/asmdisks/data1.dsk bs=1M count=3000
        dd if=/dev/zero of=/u01/asmdisks/data2.dsk bs=1M count=3000
        dd if=/dev/zero of=/u01/asmdisks/data3.dsk bs=1M count=3000
        dd if=/dev/zero of=/u01/asmdisks/data4.dsk bs=1M count=3000
        dd if=/dev/zero of=/u01/asmdisks/fra1.dsk bs=1M count=3000
        dd if=/dev/zero of=/u01/asmdisks/fra2.dsk bs=1M count=3000

        dd if=/dev/zero of=/u01/asmdisks/fra4.dsk bs=1M count=3000
        chown oracle:oinstall /u01/asmdisks/*.dsk
        chmod 666 /u01/asmdisks/*.dsk

You may not have the package installed

losetup should be in /sbin

Verify that, and if not, I think the RPM is util-linux

On my Oracle RH 5.3 it is util-linux-2.13-0.50.el5

in my /sbin directory I have (among many other) this line:

-rwxr-xr-x 1 root root   14476 Aug 21  2007 losetup

It could be due to how you logged in as root. Try "su - root" and see if /sbin is in your PATH.
