The permissions on the ssd 'instance path' for disk in an SSA are created with 600 permissions. They should be 0640 for a non-root user to be able to read them. For example,
# ls -lL /dev/rdsk/c2t0d0s1 crw------- 1 root sys 192,241 Jul 10 1996 /dev/rdsk/c2t0d0s1 |
crw-r----- 1 root sys 192,241 Jul 10 1996 /dev/rdsk/c2t0d0s1 |
ssd:* 0640 root sys |
