DUMP: Cannot open dump device `/dev/rdsk/c2t0d0s1': Permission denied


When using ufsdump(1M) as user sys (UID 3) on a disk drive in an SSA, the ufsdump(1M) command fails with this message.


Six-hundred (600) permissions were created on the SSD "instance path" for a disk drive in an SSA. For a non-root user to read them, there should have been 0640. For example, if you see this:

# ls -lL /dev/rdsk/c2t0d0s1
crw-------   1 root     sys      192,241 Jul 10  1996 /dev/rdsk/c2t0d0s1
Change it to this:

crw-r-----   1 root     sys      192,241 Jul 10  1996 /dev/rdsk/c2t0d0s1
You might also want to add the following line:

ssd:* 0640 root sys   
to the /etc/minor_perm file, so subsequently added arrays do not have the same problem.
