You're sure sd[c-f] is not the same device on multiple paths?
How can I be sure? How do I check?
This SAN exports another set of 4 LUNs to a different server and they
work just fine.
It does look like you're seing the same disk through four different paths.
What OS is the other server running? The people that setup the SAN should
know if it is multi pathed or not.
Thanks.
Looks like it might be a problem with the type of firmware we have on
the SAN which only allows for one active fiber channel controller at a
time. The second controller should be used only when the first one
fails. What we were doing was to export the first set of 4 volumes
through one controller and another set of 4 on the other controller,
hence the problem. We will either have to change the firmware to allow
for 2 active controllers (no failover spare) or buy a switch to make all
the volumes accessible to more than one server through the first fc
controller.
