Lock LUN

[mt_1299]

We have an active two-node ServiceGuard cluster running on 11.31 configured by a consultant.

An ioscan -fnNkC disk shows the disk used as the Lock LUN as having three partitions.

What are each of the Lock LUN partitions used for?

Thanks.

Serviceguard documentation says that creating three partitions is a requirement:

http://docs.hp.com/en/B3936-90144/ch05s01.html#cacghbcd

The first partition must apparently be dedicated for EFI (perhaps a requirement of the Itanium firmware, for I see no other possible reason???), the second (and smallest) contains the lock, and the third can be used however you wish.
