Persistent reservations

- -

Support for PERSISTENT RESERVE IN and PERSISTENT RESERVE OUT is required to - work in many cluster environments, e.g. Windows 2003 Cluster.

- -

For implementation you should use scst_reserve_local() and - scst_release_local() as a base. You should store all reservation keys - for in files in /var/scst, one file per device - (it would allow to eliminate additional locking), like - /var/scst/boot_disk for device "boot_disk" and load them in memory, when - device would be registered.

- -

In the first version it can be done for virtual - devices only and reject PERSISTENT RESERVE IN and OUT commands for - pass-through devices with "COMMAND NOT SUPPORTED" sense data.
