[OmniOS-discuss] Missing device but format shows it exists?

[steve at linuxsuite.org]

 Howdy!

          This seems wierd....  I am adding cache and log mirrors and
everything
works fine but then their is a missing device, but format shows the partition
is there. devfsadmn does not add the device file.   d0s0 - d0s6 and d0s8-d015
are there but d0s7  is missing?

 thoughts?
