Guys,
Another question on this:
We're running sybase databases on these servers - they use RAW
partitions. If we mirror those, what happens when the disk fails and has
to switch over to the mirror? Does it request (for eg) /dev/vg01/sybdb1
and just go to the first available PE that the LE points to?
Thanks
Ronelle
