DVD Burning I/O Error

[Patrick Ware_1]

Hello, when I executed this command:

root@server:/opt/ignite/lbinia> growisofs -Z /dev/rdsk/c1t2d0=/PA.iso


I get the following output and error:

Executing 'builtin_dd if=/PA.iso of=/dev/rscsi/c1t2l0 obs=32k seek=0'
:-[ MODE SELECT failed with SK=4h/ASC=47h/ACQ=00h]: I/O error


Anyone have any idea what is happeneing?

Here is the drive info:
