Partition and Label the Devices 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). Caution 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. Example Press Enter to label a disk Enter r for partition menu Enter e for expert menu # fx -x fx version 6.5, Jul 11, 1999 fx: "device-name" = (dksc) Enter the SCSI controller # fx: ctlr# = (0) 8 Enter the SCSI TID fx: drive# = (1) 0 Enter the LUN # fx: lun# = (0) 15 ...opening dksc(8,0,15) ...drive selftest...OK Scsi drive type == HITACHI OPEN-3 5244 ----- please choose one (?

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. 26 hp surestore disk array xp operating system configuration guide: SGI IRIX
