You can avoid some of the quoting issues by using a here document. In my limited testing, this causes the remote hosts' MOTD messages to be displayed, which may or may not be a problem for you; depends on the SSH version and stuff like that, too, I guess.

Code:
#!/bin/sh
while read host
do
  ssh $host <<"__HERE"
    for i in `lslpp -l |grep tsm`
    do
      lslpp -Lc $i |grep -v State |tr ':' ',' |awk -F, '{print $2, "," , $3}'
    done
__HERE
done <server_list.txt > ./test.csv
chmod 644 test.csv

Whatever you really want, chmod 777 is almost guaranteed to be wrong; I changed it to 644.

Looks to me like the redirection to test.csv was also in the wrong place (you would be overwriting it for each host) so I changed that as well.

ssh-ldap-helper

SSH-LDAP-HELPER(8)					    BSD System Manager's Manual 					SSH-LDAP-HELPER(8)

NAME

     ssh-ldap-helper -- sshd helper program for ldap support

SYNOPSIS

     ssh-ldap-helper [-devw] [-f file] [-s user]

DESCRIPTION

     ssh-ldap-helper is used by sshd(1) to access keys provided by an LDAP.  ssh-ldap-helper is disabled by default and can only be enabled in the
     sshd configuration file /etc/ssh/sshd_config by setting AuthorizedKeysCommand to ``/usr/libexec/openssh/ssh-ldap-wrapper''.

     ssh-ldap-helper is not intended to be invoked by the user, but from sshd(8) via ssh-ldap-wrapper.

     The options are as follows:

     -d      Set the debug mode; ssh-ldap-helper prints all logs to stderr instead of syslog.

     -e      Implies -w; ssh-ldap-helper halts if it encounters an unknown item in the ldap.conf file.

     -f      ssh-ldap-helper uses this file as the ldap configuration file instead of /etc/ssh/ldap.conf (default).

     -s      ssh-ldap-helper prints out the user's keys to stdout and exits.

     -v      Implies -d; increases verbosity.

     -w      ssh-ldap-helper writes warnings about unknown items in the ldap.conf configuration file.

SEE ALSO

     sshd(8), sshd_config(5), ssh-ldap.conf(5),

HISTORY

     ssh-ldap-helper first appeared in OpenSSH 5.5 + PKA-LDAP .
