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:
to the /etc/minor_perm
file, so subsequently added arrays do not have the same problem.
