symmetrix inquiry commands not working

Hi all,

On the aix host most of symcli commands are working like sympd , symdg , symcfg but
About inquiry commands like syminq , syminq ¿sym are not working ..what¿s the problem
Do I need to install inq utitilty for that ..it comes with symcli right????
See here if I type syminq it takes me to next command prompt without giving any result..

server1/root: /usr/symcli/bin > syminq
server1/root: /usr/symcli/bin >

server1/root: /usr/symcli/bin > syminq -sym
server1/root: /usr/symcli/bin >



What¿s the problem..

Thank you,
