Business copy error on hp-ux running from a shell script

[Rick Copley]

Below is a snippet of a script that is for Business Copy clones and snaps, we are running it on an HP-UX system with an XP2400 Array. When we run the script, intermittently we get this error, and bombs on either a paircreate aor a pairsplit command. When we run these commands manually from the command line, it always works.

This is the error:
: [EX_CMDRJE] An order to the control/command device was rejected

This is the script syntax...
$PAIRSPLIT="/usr/bin/pairsplit"
$PAIREVTWAIT="/usr/bin/pairevtwait"

$PAIRSPLIT -IBC01 -g c1 -S
$PAIREVTWAIT -IBC01 -g c1 -ss smpl -t 60
if [ "$?" -ne 0 ]
then
echo "ERROR: Split of $CLONE to Simplex has timed out - command aborted"
exit 1
else
echo "CLONE is now in simplex mode test successful..."
fi

Any help would be appreciated..

Thanks,

Ed

hi,

if you run this script from sh manually it always works ??? i yes, them you need to define some parameters for the shell.

Hi Ed,

As the previous posts state, it seems like a problem with your ENV variables set on the shell prior to execution of the script.

Post your HORCM files, and scripts and I will have a look.

The errors are always cryptic and don't lead you in the right direction. The way to get it right is by doing everything as per the book.

Thanks for your help...

env command shows

SHELL=/sbin/sh

and the script indicates:

oa1406:/scripts >head bcopy.sh
#!/bin/ksh

Can this be causing a problem?

Thanks again..

Ed

[PP BIJU KRISHNAN]

SHELL=/bin/sh is your default shell and

#!/bin/ksh is the shebang

This is not likely to cause any problem to the execution.

This is the horcm files and the script, sorry it is pretty lengthly:

Hi Ed,

Sorry buried in work....

You need to set the variables via the script, coz the script runs in its own env

set HORCC_MRCF=1
set HORCMINST=0

Add these lines to the beginning of the script and I think the error would be eliminated.
