Partitioning And Labeling The Devices - HP XP48 Configuration Manual

Partitioning and labeling the devices

Caution
Example
Installation
After new device recognition has been verified, 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-x
logical unit.
