hi!
for now we have all our drives split over 2 fabrics.
all even drives over fabric1
all uneven dirves over fabric2
that was fine as long as we had no library at a second location
now we depend on a WAN connection, administered by a local provider. (2 dark-fibre)
some days ago we where told fibre1 would have a "downtime"
sadly the provider swapped the to cables ^^.
so we took 50% of our drive manually offline. the other 50% _went_ offline.
questions:
- i guess this KEY you have to enter is NOT free? Or do i really just drive to the 2nd location and check if its already in the L-frame as the documentation suggests?
- is anyone using datapathfailover?
- is anyone using datapathfailover on HP/UX?
thanks!
