DUMP: Cannot open dump device `/dev/rdsk/c2t0d0s1': Permission denied
Cause
When using ufsdump(1M) as user sys (UID 3) on a disk drive in a SSA, the ufsdump(1M) command fails with the message.
Action
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
|
Change it so it reads:
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.
