Configuring storage using Disk Utility
After connecting the PFC 500 storage system to the Profile XP Media Platform, you
must use the Disk Utility to bind the storage system’s disk modules into logical units
(LUNs) and create a video file system that is recognizable by the Profile XP Media
Platform.
This section includes the following:
• About configuring storage (page 69)
• Configuring storage without hot spare drives (page 71)
• Configuring storage to include hot spare drives (page 75)
• Changing the volume name (page 80)
• Expanding storage (page 83)
• Determining which disk modules make up a LUN (page 85)
About configuring storage
This section describes terms and concepts related to configuring your the PFC500
storage system. Topics include:
• Binding disk modules
• Unbinding disk modules
• Creating a video file system
• Expanding Storage
• File system volume name
• Using Hot Spare disks
Binding disk modules
Binding the disk modules hardware formats them into a logical units called LUNs.
The disks that make up a LUN are accessed as a contiguous disk space. Disk modules
must be bound before they can be part of the video storage file system.
You can use the Profile XP Disk Utility to bind disks modules as Data LUNs (RAID-3
containing 4 data disks and 1 parity disk) or as hot spare LUNs, depending on the
storage needs of your system.
A PFC chassis can contain up to 10 drives. For simplicity, the Disk Utility
automatically groups consecutive disk modules into unbound LUNs, that is, disks 0-4
and 5-9 are grouped as unbound LUNs. To help in finding the physical location of a
LUN in large systems, refer to “Determining which disk modules make up a LUN”
on page 85.
After binding, disk modules become slot specific and cannot be moved to other disk
module slots.
