Restrict the use of a partition - Help please!

[BiancaP.]

I have a two HP DL380 servers and one HP MSA500 storage with 10 disks of 146GB.

I need to restrict the use of a partition to get more security.
Like:
When I mount a partition in one server, I don't wanna that this partition could be mount again in the another server.
Because it was happen and i lost the partition.

Any help, please?????

You should be able to use SSP in ACU pointed at the MSA500 controller.

You'll need to know the WWN of your fibre HBAs.

As you've found, you cannot have two hosts accessing the same LUN at the same time, UNLESS your using clustering software...
