If you are using LSM and multiple shared SCSI buses with storage shelves,
you need to:
• Mirror the clusterwide root (/), /usr, and /var file systems across two
shared SCSI buses.
• Place the boot disk for each member system on a separate shared SCSI
bus.
• Provide another shared SCSI bus for the quorum disk.
