After new device recognition has been verified, you need to partition the new SCSI
disk devices using the fx utility. When the disk array is connected through a fabric
switch, you must specify the device file when starting the fx utility. After setting the
partitions for a device, verify the partitions using the prtvtoc command.
The IRIX system controls disk devices using partitions. One LUN can be divided into a
maximum of sixteen partitions (primary partition 0 through 15). The maximum
capacity per partition is not limited. Partitions 8 (vh) and 9 are reserved and are used
for storing disk management information. Partition 10 is also reserved. Therefore, the
number of available partitions per device is thirteen (0 to 7 and 11 to 15).
Do not partition or label the Data Exchange (DE) devices. This will prevent the DE
software from accessing the device. These devices must be installed and accessed as
raw devices.
To partition and label the devices:
1. Use the fx utility to create and label the partitions for each new OPEN-K/3/8/9/E
logical unit.

Warning: you will need to re-install all software and restore user data from
backups after changing the partition layout. Changing partitions will cause
all data on the drive to be lost. Be sure you have the drive backed up if it
contains any user data.
