I created a script to check for tsm backup status on linux hosts. Script uses a source file to connect to each host and run a dsmc command on each host and write the output back to a output file located on the parent server where the script is running. The script works fine for the first 2 hosts including the parent and then fails with the following error.
Pseudo-terminal will not be allocated because stdin is not a terminal.
Code:
#!/bin/bash
fdate=$(date "+%Y-%m-%d")
export curr_host=`hostname`
if [ ! -s ${HOME}/hosts.txt ]
then
echo "Hosts file is missing or a zero-byte file. Exiting the process" >> log.txt
exit 1
else
echo $HOSTNAME >> tsm_bkp_$fdate.txt
dsmc q fi | awk '{print $2,$5}'|sed '0,/----/d' >> tsm_bkp_$fdate.txt
while read line
do
echo $line >> tsm_bkp_$fdate.txt
ssh -t $line dsmc q fi| awk '{print $2,$5}'|sed '0,/----/d' >> tsm_bkp_$fdate.txt
done < ${HOME}/hosts.txt
fi
I searched for the above error in other *nix forums and tried using 'ssh -tt or -T' in the script per others suggestions. But I still get the same error.
