SAPINST error during extraction under AIX

Dear Experts,

I am trying to install SAP ERP ECC6 EHP7 under operating system IBM AIX 7.1 and oracle 11g through SWPM ( new sapinst)

first I open xmanager Broadcast then assign my desktop ip in DISPLAY variable  for example my desktop IP is 192.68.200.20 then I set DISPALY variable in AIX as   export DISPLAY=192.168.200.20:0.0   then xclock working now

I create a folder under /oracle/install      ( for SAP ERP installation directory)

and run command /cddump/solman71sr1/aftersapcar/swpm/sapinst

it give me following error

# /cddump/solman71sr1/aftersapcar/swpm/sapinst

[=                             ] / extracting... iaextract.c:315: error in writing extracted file: No space left on device

as per sapnote  1927860   I give enviornment variable TEMPDIR to /tmp

export TEMPDIR=/tmp

tmp is 20GB of space free

main mount point created

/oracle

/usr/sap

/sapmnt

Note

another mount partition /usr is used 98%

Please guide me how to resolved this issue

Regards
