We installed snapdrive on backup server with OS windows 2008 r2, we mount one snapshot LUN through FC to become a drive (e.g X:), I don't know why it show two LUNs on snapdrive.
The backup server have one FC to SAN Switch, SAN switch -> two filers head. zoning is backup server FC port 2-> first filer head 0a, backup server FC port 2-> second filer head 0b.
Anyone know what problem is?
Quite likely it is showing secondary path via the 2nd head (not owning the LUN) & cluster interconnect down to the actual LUN on the 1st head.
You need multipathing to sort that out I am afraid.
