Right :
- It can be done on STK L700 (depends of firmware), it is also the default on
SL8500.
- soft zoning with WWPN is also OK with Brocade
--> no need to "rezone" with a drive change, no need for technician to recall
to reuse the old WWPN of the failed drive to the new one : very very useful.

It is the default config on SL500 libraries (ok - depends on the firmware,
really old FW didn't do it)...
The WWPN's are a function of the drive bay location rather than the
drive's native WWPN... Changing drives works fine for us with solaris
9 or 10, lpfc or leadville... Our san people zone on the WWPN's not
hard zoning. Seen drive changes work on both mcdata and cisco sans.
If you switch dwwn off, then all your drive's would have different WWPN's and
if the zoning hasn't been updated to match that's why youd be getting errors.

Hi,
Does anyone have a STK library with DWWN turn on? If yes or no I would like to
know why? We are having I/O issues on our tape drives and I'm trying to find
if there is something we missed.
We did some testing with a new backup server with dwwn off and everything
looked good. When we moved the server into production we had dwwn turned on
and now we are getting I/O error on the drives connected into our SAN
during backups. At first I thought the problem was with the st.conf, but
now I'm not too sure.
We have been told that another site has their tape drives going to a SAN
enivornment with no issues, but they do not have dwwn turn on.
We have a L700e tape library with IBM LTO2 tape drives with code 67U1.
Going into a SAN with Brocade switch 24000.
Thanks,
Paul
